摘要： 为了减少不同发射功率节点间的分组冲突,提出了一种无线自组织网的发送功率等级交互机制,从而在网络局部推选出适合的公共发射功率等级.网络仿真结果表明在静止网络中采用该机制后可改进网络吞吐量,并减少部分能量消耗.

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.
