An Efficient Neighbor Node Detection Using AODV in MANET

MANET is a self configuring and centralized multi hop wireless network. Adhoc achieve efficient routing but due to high mobility network can change the structure dynamically so route may be disconnected and route selection, route combinations are not an easy issue to solve. Especially detecting vulnerable node to both internal and external attacks are challenging and major issue in the Adhoc network. This problem affects routing efficiency and performance of the network. In this paper, suggest for ADOV routing protocol based on signal to noise ratio, intensity, flow capacity and set the relative position of the node in MANET. By adding this extra parameter we can easily detect both internal and external attacks. Proposed approach provides optimal secure routing to give the appropriate solution against neighbor attacks in MANET. The performance of proposed system is simulated by NS2.
