MANETS are randomly distributed self-configurable networks used in an ad-hoc fashion. Due to its increasing network data, load balancing becomes an unmanageable aspect in these networks. Various load balancing techniques though have been proposed; Random, Scheduling and Evolutionary load balancing models differentiates and allocates the load into different levels, providing a maximum network manageable...
There were two strategies for the data forwarding in the content-centric networking (CCN): forwarding strategy and routing strategy. Forwarding strategy only considered a separated node rather than the whole network performance, and Interest flooding led to the network overhead and redundancy as well. As for routing strategy in CCN, each node was required to run the protocol. It was a waste of routing...
Wireless Sensor Network is one of the most advance technology in the field of Information Technology because of the various applications implemented in. Coverage issue is a fundamental research in the Wireless Sensor Networks. Many Researchers have implemented techniques in order to reduce the coverage area of the sensor node to conserve the nodes energy. In this paper, a model to use intelligent...
The paper first proposes a new idea of local nodes first for resource locating in overlay networks. And then, based on this idea, small world phenomenon as well as Kademlia protocol, a resource locating model with local nodes first, which is called as RLM-LNF, is designed for discovering resources in overlay network. The RLM-LNF model includes two layers structure that are super node layer and general...
In Gnutella-like P2P networks, blind flooding causes a large number of redundant messages, and this makes such networks not scalable. Previous researchers noticed three types of nodes in P2P networks: super nodes which share a large number of resources and tend to have long online time, stable nodes sharing a number of resources and having long online time, and dynamic nodes that share few resources...
In this paper the new method for determining the number of super node in heterogeneous wireless sensor network based on evolutionary algorithms are presented. The network consisting of several resource-rich supernodes, used for data relaying, and a large number of energy-constrained wireless sensor nodes. The main contribution of this paper is to reach an optimum trade off between number of super...
In this paper we have explored the issue of how to integrate semantics searching into a mobile P2P system. Our semantic searching approach is based on LSH where the semantically close documents are clustered to the same peers with high probability. For a query, we chose several points randomly from the neighborhood of the query as the semantic searching key. Our approach only adds index information...
Wireless sensor networks need an efficient and reliable reprogramming service to facilitate management and maintenance tasks. In this paper, we propose a reprogramming mechanism, which is based on the hierarchy in the network. We divide the nodes in the network into two types of nodes (i.e. super nodes and normal nodes). We first send codes to nodes in the upper layer of the node hierarchy (i.e.,...
