Mobile Ad hoc Networks (MANETs) have seen vast application and continuous development. A good number of protocols have evolved to perform efficient routing in MANETs in order to improve the communication. Two protocols Cooperative Opportunistic Routing Scheme in Mobile Ad Hoc Networks(CORMAN) and Proactive Source Routing (PSR) have been implemented for MANETs and their routing performance have been improved.
In this paper, we analyze the lifetime of the MANET by fixing the initial energy of nodes to see how much energy is being consumed by these protocols. Simulations are performed in the network simulator NS-2.
