一种基于无线传感器网络的跨层功率控制策略

A strategy of cross-layer power control based on wireless sensor network

为了解决无线传感器网络中节点能源的有限性问题，提出～种跨层的功率控制策略，对基于网络层和基于MAC层的单层功率控制协议进行改进融合。经过仿真实验证明，此方法极大的提高了无线传感器网络的整体性能，有效延长了网络寿命。

In order to solve the problem of limited nodes energy in wireless sensor network., a method of cross-layer power control is proposed. It improves and integrates one-layer power control protocols based on network layer and MAC layer. Finally, it is proved by simulation experiment that this method improves overall performances of wireless sensor network largely and prolongs the network lifetime efficiently
