Mobile Ad hoc Networks consist of mobile nodes with limited battery power. The critical issue for routing in mobile ad hoc network is how to select a stable path with longer lifetime since mobility and power drain of a node causes frequent path failure. This path failure causes frequent route discovery which affects the performance of the routing protocol. The path failure also increases computational overhead of the nodes. Hence, in this paper, the authors propose three algorithms to estimate the stability of the route by considering the energy drain of the nodes and the rate of mobility.
