Abstract: To reduce the packet collisions among nodes using different transmission power, a transmission power level exchange(TPLE) mechanism is proposed for wireless ad hoc networks to find an appropriate common transmit power level across the network. Simulation results show that this mechanism can improve network throughput and result in lower energy consumption in static network.
