摘　　要：通过对MAC层能量消耗因素的分析,介绍了能量优化的原则,从而得出通过设计MAC协议来提高无线个人区域网能量效率的方法．通过对IEEE802．15．4 MAC协议能量有效性的仿真研究可以看出,尽管IEEE802．15．4标准的设计目标为低功耗,但这种标准在ad hoc网络中的能量效率仍然不够理想．因此,设计适用于无线个人区域网并且能量效率高的MAC协议仍然是十分有价值和具有挑战性的工作．Through analysis of the factors of energy consumption, the principle of energy optimization is demonstrated. By designing MAC protocol, the energy efficiency of wireless personal area network is raised. From the simulation research of energy efficiency to IEEE802. 15.4 MAC protocol, it is seen that the erergy efficiency for this standard is still not ideal in multi-hop ad hoe network although the design object of this standard is of low power consumption. Therefore, it is still a valuable and challenging work to design MAC protocol with high energy efficiency for wireless personal area network.
