Abstract

Evaluating a routing protocol in MANETS is a difficult task due to mobility of nodes and decentralized administration. In Adhoc On demand Distance Vector routing (AODV) protocol the routes are found only on need and the connection setup delay is less. An authenticated secure data communication protocol E-AODV (Energy based AODV) is proposed in this work which ensures the security of Confidentiality, Integrity and Availability triangle. Confidentiality is provided by calculating Intermediate Trust Value (ITV) for all nodes between source and destination and only the nodes which possess highest ITV is used for data transmission. Integrity is attained by an encryption algorithm called digital signature algorithm which is used at the time of data transmission from source to destination node. Availability have been provided by calculating the residual energy of each node so that nodes which possess highest energy are used for data transmission. Simulation results using NS2 also prove that the performance level of throughput, Energy consumption and packet delivery ratio in E-AODV increases with that of AODV routing protocol. The results obtained are trained using Back propagation algorithm and the effectiveness of the proposed system is checked by ANN approach.
