Ambulatory networks as a result of high mobility of nodes and routing are one of the most important challenges that will result in reduced network performance. So far, the routing methods based on the geographical location of those nodes act faced with more fortunate. Reducing the overhead associated with data location of nodes in the network, including the challenges of location services which is considered in the proposal to reduce the control overhead that we tried to take advantage of opportunistic routing protocol integrating the idea of geographical GPSR {Greedy Perimeter Stateless Routing} make this possible. We used NS2 for simulating and then improve on GPSR and new algorithms were compared. The results show that the proposed method is less control overhead and get rate is more than GPSR.
