To overcome the problems faced in our existing system we go for the proposed work for encouraging the network processing. In our proposed system we are going to select a fuzzy c-means algorithm for clustering process. Fuzzy c-means (FCM) is a data clustering technique in which a dataset is grouped into n clusters with every data point in the dataset belonging to every cluster to a certain degree. Fuzzy c-means (FCM) is a method of clustering which allows one piece of data to belong to two or more clusters. Star Student ProjectThe fuzzy takes the values of numbers between 0 and 1. According to the rule of fuzzy we are clustering the nodes. After the creation of cluster we have to choose the path from source to the destination. For choosing the path we have to use the Minimum Spanning Tree (MST) algorithm. A minimum spanning tree (MST) of an edge-weighted graph is a spanning tree whose weight (the sum of the weights of its edges) is no larger than the weight of any other spanning tree. This minimum spanning tree find out the minimum of weight for the nodes and then it calculate the best path between the source and the destination for transmission. This kind of proposed system can provide the efficient way of transmission between the source and destination.
Star Student Project
This is our first module. In our concept we form the 50 nodes. Each of which are mobile nodes and also each of which contains the mesh client. The node formation is the first step of our process. In which nodes are added in to the network. The nodes are in mobile nature. .The nodes are free to move. The node movements are updated by each node. This forms the topology. The topology is nothing but how the nodes interconnect with each other. Here we first select router and mesh client in order to make packet transmission. Then nearest neighbor nodes are chosen for packet forwarding. In our network each of which nodes contain the mesh client. But the mesh client does not have the knowledge of their locations. So first of all we need to finding out the location. We find out the location with the help of the GPS value receives by each node.Before finding the inter and intra router form the cluster using the k-means routing algorithm. From that group we find out the inter and intra router. In this module we find the redundant router and act as this router as free for future use. If we find anyone inter router in one group. This is our final stage. After selection of the router and the mesh client location made packet transmission. Packet transmission means the mesh client will inform the all node information into the router.

Ns3 projects in Hawaii Note that in the license life cycle is interlinked with the usage session so that it is affected by all events that affect the usage session. Let us now consider a concurrent users license, Null means the license does not exist at the host. Once a license is provided to the host it becomesns3 projects in Hawaii Available. Once a guest user’s request is accepted so that the provisioning of resources may begin the license is In Use. When the user suspends a usage session, the corresponding license becomes Available When the suspended session is resumed, the license is In Use. Finally, the license may be withdrawn. The above life cycles are described in terms of state diagrams.
ns3 projects in Hawaii In general, different license types support different state diagrams. For example, shows, a Single Usage license remains In Use when the session is uspended and becomes Null when the associated usage session ends. A suspended session may be resumed, making the session Active. ns3 projects in HawaiiIn Licit, the state of a license is maintained by the licensee even as the usage-sessions are instantiated in a distributed manner at the various hosts. Doing so enables us to support the use case where a host denies access to a user because of the host’s local policies. In this case, the user can try elsewhere. cheduling Strategies Often an organization must optimize its license usage according to its local needs.
ns3 projects in Hawaii Usage licenses often provide a lot of flexibility in this regard. For example, a typical license would specify the maximum number of concurrent users. It would not specify which users, if any, are to be accorded priority over others. Suppose NCSU has obtained a license for concurrent users.ns3 projects in Hawaii NCSU could arbitrarily reserve of the licensed seats for faculty and only allow up to student users of a licensee: In any case, it is the licensee’s prerogative to Alternatively, suppose all 100 seats are taken.

ns3 projects in Missouri
ns3 projects in Missouri Therefore, the licensee requests the value of this attribute for Alice from its own attribute service, which returns “computer science.” next, because the vocabulary states that this attribute isns3 projects in Missouri resolved by the host, the licensee requests the value of number of processors from the host instead of its own attribute service. ns3 projects in Missouri Based on the above information, the licensee finds that it can provide access to Alice. It is to be noted that the challenge of determining a value for an attribute rests with the attribute service.
ns3 projects in Missouri A site may introduce any apparently idiosyncratic attributes that make sense for its local needs. All it needs to do is ensure that the attribute service can resolve such attributes for the entity involved. For example, a site may introduce an ad hoc attribute “social-influence” with values “high” and “low” and use this attribute within a policy to decide which users are to be accorded special treatment in accessing ns3 projects in Missouri certain resources. The attribute service on its part may calculate a value for social influence by querying a social network website. This ad hoc example is meant to illustrate that Licit can work in a wide range of settings. License and Usage Session Life Cycles
ns3 projects in Missouri We model each license as an object with a life cycle. Not surprisingly, different types of licenses exhibit different life cycles and constrain possible enactments in different ways. Additionally, we model a usage session as an object with a life cycle of its own. , the usage session’sns3 projects in Missouri life cycle startsns3 projects in Missouri when a guest user’s request is accepted so that the provisioning of resources may begin. The usage session at this point becomes Active. A usage session may be suspended, thereby making it Dormant, and a suspended session resumed, thereby making it Active once again. The user can end the session from either Dormant or Active state.

We can now express a ns3 projects in Territoriesbase vocabulary that includes the attributes that feature in the license types of. Table classifies these attributes based on the entity to which each applies. Read the first row of Table as follows: The attribute role describes the subject and is resolved by the licensee;ns3 projects in Territories example values for role are “faculty” and “student. Read the subsequent rows following the same pattern.
ns3 projects in Territories IEEE TRANSACTIONS ON SERVICES COMPUTING -MARCH TABLE Examples of Commonly Occurring Usage Licenses An information model for license attributes.ns3 projects in Territories TABLE Classification of Attributes That Feature in Common Licenses Some attributes may be particular to the licensee and must be resolved by it. Some licenses may be based on information that can only be provided by the user, for example, a user’s acceptance of the terms regarding the purpose of use. We include these with the licensee.
ns3 projects in Territories Licit is not limited to the above attributes, and a site may introduce additional attributes as needed. Whether a site uses the above or its site-specific attributes, it needs to specify the agent each attribute is resolved by so that a licensee would contact that agent to request values for ns3 projects in Territories those attributes. Let us consider how an attribute vocabulary may be used. Suppose Alice, a computer science student at NCCU requests a usage session with Matlab at NCSU The host finds that a node is available so it forwards the request to the licensee. The licensee finds that its license for Matlab involves checking the subject’s attribute department and the number of processors of the node on which Matlab will be deployed

ns3 projects in Denmark
ns3 projects in Denmark A license vocabulary comprises attributes, each of exactly one data type. The attributes involved in a license describe the subject resource, action, environment, and sometimes the license identifier. An example of an attribute that describes the constraints on a license identified by a license identifieris cumulative usage. ns3 projects in DenmarkThe environment attribute may indicate one or more of the following: start or end time, and the identifier for the node on which resource is to be deployed. An example of an environment type attribute, an attribute that ns3 projects in Denmarkescribes the node, is number of processors.
ns3 projects in Denmark We introduce another entity type, context, to include attributes that characterize an association of more than one of the subject, resource, action, or environment. ns3 projects in DenmarkAn example is the attribute permitted usage, which describes permission of a subject to perform an action on a resource in an environment. In a significant break from current approaches to license in our model, an attribute is resolved by an agent instead of a service location.
ns3 projects in Denmark This is unavoidable in a federated setting, since the location at which to resolve any attribute associated with the host, such as the number of processors, is known only at runtime. This is because the host and thereby the node at which the requested resource is deployed is also known only at runtime.ns3 projects in Denmark The agent-based solution enables such latebinding of attributes to values because the licensee can simply ask the appropriate agent, in this case the host, to resolve attributes such as number of processors. To this end, the licensee would provide values of some attributes to determine the value of a requested attribute.

FORMALIZING USAGE LICENSES We describe the structure and elements of a usage ns3 projects in Wyoming license that formalizes a license that a licensee site would have obtained for the benefit of its user communityns3 projects in Wyoming .
ns3 projects in Wyoming We propose a simple information model using which a site can specify a vocabulary needed for evaluating its usage licenses, determining whether a particular user request is valid according to a specific license. We begin with a classificationns3 projects in Wyoming of the license types gathered ns3 projects in Wyoming from interviews with academic IT experts and which arise commonly in modern practice. From this classification, we determine a base vocabulary that can be used to state licenses. captures the commonly occurring usage license types.

KEDIYAL AND ADMINISTERING USAGE LICENSES IN FEDERATED An Information Model for License Attributes presents an information model for the attributes that may feature in licenses. The policy representation of a license specifies the predicates that operate on these attributes.ns3 projects in Wyoming Each site would use this information model to specify its custom vocabulary of attributes. The main benefit of developing an information mod el is to overcome the challenge of heterogeneity, specifically, to enable a site in a federation to interpret the terms in a vocabulary that has been specified by another site.

ns3 projects in Mississippi
ns3 projects in Mississippi Further, to enforce certain usage constraints based on history and state or potentially in anticipation of demand, each party would need to monitor events and behave proactivelyand thus each of the parties must be able to entertain interrupts from others. We adopt a policy-based approach as the underlying framework for the specification of agents and their interactions. Policies yield greater perspicuity and modularity than procedural representations and have been used in a variety of settings, most commonly access control We ns3 projects in Mississippi do not propose a new policy language or engine. The Licit approach is implemented over existing technologies.
ns3 projects in Mississippi We show how to represent licenses, license dministration strategies, and resource allocation considerations as policies. Licit agents can exchange policies with each other. For each agent, we organize the various in a simple hierarchical structure that yields the ns3 projects in Mississippi desired computations in a natural manner. Contributions We develop a policy-based approach for administeringfederated computing environments, such as hose enabled through the expansion of cloud computing technologies ns3 projects in Mississippi.
ns3 projects in Mississippi The novelty of the Licit approach lies in its treatment of policies in a federated setting. Licit is framed in the context of usage licenses for software applications, and can be seen as demonstrating service computing techniques to support further services. However, the basic ideas of both licensing and of Licit apply to resources in generalincluding databases, data streams, sensors, and so onthatns3 projects in Mississippi could potentially be subject to a usage license. The rest of this paper is organized as follows: Section formalizes the problem domain by laying out various license types, scheduling strategies, the information model, and the states in the life cycles of a license and of a usage session.ns3 projects in Mississippi Section provides a technical view of the system in detail, including its architecture, the representation of a license as a policy, concepts of a scheduling policy, and the organization of policies at a site.

ns3 projects in Georgia
ns3 projects in Georgia Approach in Brief We propose Licit, an approach that addresses ns3 projects in Georgia the foregoing challenges via license, scheduling, and site policies, respectively. A license policy states the terms between the licenser and licensee, for example, a license to use concurrent instances of Matlab. ns3 projects in Georgia A scheduling policy states how the licensee chooses to opportunistically exploit the license, for example, by preempting members of one role in favor of another.
ns3 projects in Georgia Specifically, the licensee might prefer teachers over students so that the oldest instance in use by a student is terminated if necessary to fulfill a request made by a teacher. A site policy protects the interest of a particular provider by capturing its preferences when it makes its resources available in a federation.ns3 projects in Georgia For example, NCSU may share its resources with NCCU but limit access by NCCU students during the NCSU exam weekso as to give a higher priority to NCSU students during that time. Licit applies policy-based agentscomputationally representing each siteto collaboratively administer usage licenses.
ns3 projects in Georgia Licit involves agents who play two important roles in an ongoing engagement: licensee, who currently owns the license on the desired resource and with whom the current user is affiliated, and host, who provides the computational infrastructure over which the user would interact with the resource. ns3 projects in Georgia Agents implemented ns3 projects in Georgia over services are a natural for the present problem for the following reasons. Each site in a federation is autonomous and heterogeneous in that it may administer its licenses according to its local ns3 projects in Georgiastrategies and based on its local information model. Potentially, the sites may adopt distinct strategies and information model.

ns3 projects in Oregon
ns3 projects in Oregon IEEE TRANSACTIONS ON SERVICES COMPUTING, , JANUARY-MARCH. The authors are with the Department of Computer Science, North Carolina State ns3 projects in OregonUniversity, Raleigh,. Manuscript received university or a company obtains a site license but departments within the university or company ns3 projects in Oregonshare the cost and benefits of the license, and administer their own computing resources ns3 projects in Oregon.
Such cases are routine practice today. However, statically allocating licenses among the departments would clearly not be effective, and would obviate most benefits of ns3 projects in Oregon obtaining a site license. The common problem is that wherever parties federate, we need a way to account for usage licenses appropriately. ns3 projects in OregonDoing so is nontrivial because of the following challenges. First, in practice, usage licenses might involve considerations such as the number of concurrent users allowed. Thus, the parties must communicate the relevant information or convey appropriate decisions to one another.
ns3 projects in Oregon Second, each site may apply potentially subtle strategies to administering its licenses, even when its users are engaging through one of its collaborators. For example, a concurrent users license merely states the upper bound on the number of concurrent user seats; how to prioritize requests orns3 projects in Oregon allocate such seats is entirely up to the licensee. A practically viable approach should support such flexibility. Third, each host must be able to retain control over its resources and consequently be able to express site policies regarding how it collaborates with others. For example, NCSU may decide to share resources with NCCU all day but only after-hours with another institution in the federation.

ns3 projects in Tennessee We are pursuing a research program of developing approaches for the policybased administration of resources in federated environments. Specifically, we address the challenge of accounting for and administering software usage licenses in federated environments. To develop the above ideas further,ns3 projects in Tennessee consider a simple, but real, example of a federated computing environment. Some North Carolina institutionsincluding NC State niversity and NC Central University federate some of their computing resources through the Virtual Computing Lab , an open source cloud infrastructure.
ns3 projects in Tennessee Their motivation is that they need to provide their respective users virtual access to hosted applications such as Matlab, and federating resources enablesns3 projects in Tennessee handling peak loads better. The challenge here is that each institution’s site license covers usage by only its own faculty and students. Yet the applicable license must be accounted for correctly even when requests from one institution users are instantiated at VCL installations across the federation.
ns3 projects in Tennessee One might imagine that scenarios such as the above could be avoided if each institution simply obtained computing hardware from the other and handled its licenses independently of the other. However, to accomplish this, the site that is currently hosting a user from another ns3 projects in Tennessee site must be able to confirm that such a guest user is legitimate and that any requirements on the usage session are met, and be able to preempt the guest when necessary. That is, we need a way by which federated parties may collaborate effectively while preserving their autonomy.
