Cooperation among nodes in an ad hoc network is essential for multi-hop communications; the source nodes are using an intermediate node as relays to communicate with far off destinations, it may not be in the best interest of nodes to always accept relay requests. On the other hand, the network throughput will drop dramatically if all nodes decide not to expend energy in relaying so non-cooperative (selfish) nodes reduce cooperation by refusing to forward packets for others. There were three strategies used to solve this problem; the Tit For Tat (TFT), Live and Let Live, and Selective Drop (SD) scenario. In this work, the cooperation had discussed in new strategy resulted from the combination of the Generous Tit For Tat (GTFT) strategy with Selective Drop strategy and we measured the throughput of this strategy and it was enhanced when compared with throughput of the GTFT. The selfishness of some nodes due to the power consumption problem solved by suggestion to selecting routes that contain few hops with low drop percentage instead of many hops with high drop percentage.
