The Mobile nodes are playing most important role in Mobile Ad-Hoc Networks. The node can act as a device called router for most of the time. The nodes are mainly used for data transmission, route discovery and maintain a route. The data packets are lost, if any node moved out of the transmission range during data transmission or if a node has collision and contention. The signal strength information, routing table information, IP address, source address, destination address are stored in routing table in mobile node. Stability of the node is very important because if stability reduces, the packet will be dropped. Even though much work was done for stability by several researchers, the propagation of signal strength is not addressed properly for mobile node.
