摘　　要：研究了在自组织网络环境下CSMA/CA协议的能量消耗性能,并与传统的CSMA协议能耗性能进行比较。阐述了自组织网络中的隐藏终端和暴露终端问题,并分析CSMA/CA协议相对传统CSMA协议对该问题进行的改进。仿真结果表明,相对非坚持CSMA协议,CSMA/CA协议能够获得的能量效率更高,并且对网络负载的敏感性更低,在网络负载较高时也具有较高的能量效率。This paper studied the energy consumption of CSMA/CA under self-organized circumstances, and compared with that of traditional CSMA protocols. It described the problem of hidden and exposed terminals, and the improvement of CSMA/ CA protocol compared to traditional CSMA protocols. Simulation results show that compared with non-persistent CSMA protocol, the CSMA/CA protocol with lower sensitivity to network load, can get higher energy efficiency, and have higher energy efficiency even when the network load is higher.
