The wireless ad hoc network is the self-configuring network; where mobile nodes can leave or join the network when they want. There are various types of routing protocol in ad hoc network; by using these protocols communication can be possible. The author uses the AODV protocol for the transferring data. But there is a problem in AODV routing protocol i.e. link failure problem which is responsible for degrade the performance of the network. So, they proposed a new method is knowledge based learning algorithm. In their proposed technique, they follow new path which has highest signal strength. Second assumption is based upon the hop count similar as AODV protocol.
