Energy-balancing communication protocol based on cross-layer optimization for wireless sensor networks
基于跨层优化的能量均衡WSN通信协议*

Considering the hot spot problem in WSH,this paper proposed a new communication protocol CTMAC(cross-layer tree medium access control).Its combined the method of cross-layer with the energy-balancing mechanism,established a tree structured energy aware routing algorithm through sharing the node energy information between layers,and introduced the FRTS(future request to send)mechanism to SMAC.It could effectively prolong node's sleeping time.NS2 simulation experiments show that CTMAC has a good energy-effici...
