Mobile Ad hoc Networking (MANET) is the most impressive technology in today's Wireless communications. Cost reduction and proper utilization of battery power becomes the primary concerns for various type of routing. Cost effective lifetime prediction based routing protocol for wireless network gives an optimum path based on both cost and the lifetime of the mobile network. This paper represents an improvement algorithm for the routing protocol of Mobile Ad Hoc Network. Due to the limited battery power of mobile devices, recent research in mobile ad hoc routing is motivated towards selection of a path that maximizes the network lifetime. Another approach for the routing protocol in mobile device to select the minimum path length. This algorithm selects a path that considers both the path cost and the battery power of the mobile network. For the stability of the whole network of the MANET, the most concern thing is that, a low power node/device has to transfer information very earlier for the better improvement of the network. Otherwise the network may damage. The graphical and simulation results of the paper give a clear idea that how can we improve our network stability for the mobile ad hoc network.
