Connection-Degree Based Search and Replication in Mobile Unstructured Peer-to-Peer Networks

In MANET, it is important to efficiently manage object and traffic to improve network throughput and response time. This paper proposes a connection-degree based data search and replication scheme in mobile unstructured peer-to-peer networks. In the method, information about the path of object providers is stored at the cache of super peer at which lots of queries arrive, so that, to reduce the load of super peer, replications can be created at its neighboring nodes. It proposes an algorithm picking up a super peer among mobile nodes and making it possible to search for and utilize adaptive and up-to-date information in MANET. The method is expected to be effective since it enables access to object in spite of broken links among mobile nodes with an enhancement in network response time of searching and a decrease in communication costs. We´ll verify via a simulation how this system works efficiently.
