In Mobile Ad-hoc NETwork (MANET), a host may exhaust its power or move away without giving any notice to its cooperative nodes. It causes changes in network topology, and thus, it significantly degrades the performance of a routing protocol. Several routing protocol studies are based on node lifetime and link lifetime. This paper is to evaluate the node lifetime and the link lifetime utilizing the dynamic nature, such as the energy drain rate and the relative mobility estimation rate of nodes. These two performance metrics are integrated by route lifetime-prediction algorithm. This algorithm is carried out as follows select the least dynamic route with the longest lifetime for persistent data forwarding and node lifetime and link lifetime prediction methods.
