Security in wireless sensor network enhanced AODV routing

An ad-hoc network comprises mobile nodes that cooperate with each other using wireless connections to route both data and control packets within the network. They are characterized by the used of wireless links, dynamically changing topology, multihop connectivity and decentralized routing mechanism...
