An Approach to Identify Dishonest Nodes Using MAC Protocol inMultihop Cellular Networks
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 6
Abstract
Abstract: In mobility based networks, the mobile nodes usually relay on other node packets rather than theirown rightful packet for enhancing network performance. It happens due to the availability of some selfish ormalicious nodes which do not cooperate in transmission of received packets to honest nodes, which totallyreduces the network performance. A fairness issue arises when a selfish/malicious node access the advantage ofthe honest nodes without providing their contributions to honest nodes which significantly degrades theperformance of network and May results in failure of entire communication. In this paper, we are analyzingnetwork performance by using Message Authentication Code (MAC) Based protocol which can identifymisbehaving / malicious nodes.MAC uses only fast symmetric cryptographic operations, making it suitable formulticast networks, where latency is an important factor. For its construction, we used an efficient keyassignment based on Blom’s scheme, and a Merkle tree to provide authenticity during our identification routine.Further, this scheme support addition of new nodes in to the existing network only after proper authentication isdone.
