Anonymit Based Secure Cross Layer Routing Protocol for Mobile Adhoc Networks

In mobile adhoc network (MANET) mobile nodes exchange the messages through wireless medium with traditional layered architecture and without any infrastructure support. Now Cross layer designs approaches are the alternative to the layered architecture and support cross layer interaction between the layers. In this paper we discuss about the security of CLPC (cross layer design approach for power control) routing protocol. CLPC can improve the transmission power and also find the effective route between source and destination. In CLPC, RSS from physical layer (Received signal strength) is used to determine the reliable path between source and destination but it is vulnerable to the DOS attacks. To mitigate the attacks on CLPC, we propose a secure Cross layer power control routing protocol SCLPC. It keeps the nodes, routes and packets anonymous to defend the attacks. Designed protocol SCLPC was simulated in ns2 providing the better results for the network matrices as throughput, PDR (packet delivery ratio) and delay.
