In this paper, we study the performance of the Greedy Perimeter Stateless Routing (GPSR) [1] and the Greedy Routing for Maximum Lifetime (GRMax) [2], which is our proposal, in wireless sensor networks with random topology and grid topology. We decide to compare the performance of GPSR and GRMax in different topology of networks using the same simulation environment. Evaluation and comparison of GPSR and GRMax is done through the OPNET Modeler version 15. Results show that GRMax performs better than GPSR with respect to the number of delivered packets and number of dead nodes. With the introduction of VIP nodes GRMax avoid early network partition in networks with randomly distributed nodes and in networks with grid distribution nodes. Moreover, with the criteria used to choose the next hop node in GRMax, battery power resources are used efficiently. GRMax performs better than GPSR because with GRMax's metric, it selects a path from source to the destination which is close to the straight line.
