One of the main design constraints in mobile ad hoc networks (MANETs) is that they are power constrained. Sometimes host may run out of the power or move away without any knowledge of cooperative nodes, which results in change in topology and cause the performance issues in routing protocol. Some routing protocols on node lifetime and link lifetime address this issue. In this paper we presents a lifetime prediction routing protocol related to node and link lifetime for MANETs that maximizes the network lifetime by utilizing the dynamic nature, such as the energy drain rate and the relative mobility estimation rate of nodes. Utilizing these two performance parameter the algorithm selects the least dynamic route with the longest lifetime for maintaining the uninterrupted data flow. Finally, we present a pseudo code analysis of the proposed route lifetime prediction algorithm.
