ENHANCING SECURITY WITH LOW COMMUNICATION AND PROCESSING OVERHEAD FOR MULTI-HOP WIRELESS NETWORKS?

A multi-hop wireless network is a network in which a packet traversed in multiple successive wireless links to reach its destination. It is similar to mobile adhoc networks, but nodes in multi-hop wireless network are fixed. Multi-hop wireless networks can be deployed at less lost and it enlarges the coverage area with limited transmit power, enhance the spectral efficiency and network throughput. But the multi-hop wireless networks are vulnerable to different types of attacks. The selfish nodes in the multi-hop wireless networks do not relay other packets and by utilizing the cooperative nodes to transfer their packets to other nodes. So that the cooperative nodes are overloaded due to the high traffic. In this paper a trust based method is proposed to provide reliable route. Another method is Hybrid cryptographic has been proposed for improving security and reducing the complexity. Finally the SVM classification algorithm is proposed to efficiently classify the fair and cheating reports.
