MANET: Improved Secured Routing For AODV

Abstract — various routing protocols and techniques are being included in wireless network and making it an area for further research. Congestion avoidance and security are the major areas in Wireless routing which are having research focus. Major research in area of security is focused on key based mechanisms or third party trust management systems. Improved Routing Security is being proposed in this work which will provide the routing protocol security using validating a node for identification which is being distributed to each node through protocol. AODV (Adhoc on Demand Vector) routing is a proactive routing protocol which uses the neighbors ’ database to find the best route. The work is this paper is focusing on security over routing security and simulations are being proposed to show the improved packet delivery ration, throughput, end to end delay and reduced packet drop rate for Ad hoc On Demand Distance Vector (AODV) routing protocol. Attacks are being avoided proactively by including changes in the basic implementation of AODV routing protocol. Further in this work proposal to provide access control technique and unique key based authentication for AODV is being given. In existing work system performance may affect severely due to application of security mechanisms therefore research scope in this area is always available. Since the industry of communication is growing by leap and bounds therefore the need of continuous research in this area is very much needed
