An Efficient Location Based Anonymous Secure Routing Protocol for Mobile Ad hoc Network

Security is a major problem in the shared wireless medium of mobile ad hoc networks since it gives a way to the adversaries to launch various devastating attacks on the target network. To reduce this passive eavesdropping we propose an efficient approach for providing security for data and network. Initially, anonymity protection is provided to source, route and destination. Due to this the attacker finds it difficult to discover the source and destination. The path of packet flow is hidden from the attacker. This anonymity is provided at a low cost with improved efficiency. Also, high packet delivery ratio is achieved with the use of proactive geographical routing protocol (GRP), which is also known as position-based routing protocol. Our simulation results prove that packet delivery ratio is enhanced to a larger extent, thereby maintaining a trade-off between efficiency and security.
