Abstract

Abstract: The different MAC protocols play an important role in lifetime for WSNs.In order to obtain a certain MAC protocol in a specific environment，the analysis to a variety of MAC protocol is necessary.The differences of TDMA schedule-based MAC are discussed，starting with frame structure.An improved scheme is proposed to deal with problems of a low data throughput and a tight implementation in existing TDMA MAC protocols.And three TDMA MAC protocols based on LEACH are simulated，the simulating result corresponds with data analysis.

摘要： 无线传感器网络MAC协议对网络的生命期有着重要影响，为找到适合一定环境所使用的MAC协议，必须对不同的MAC协议进行必要的分析。从数据帧着手，分析了不同的基于TDMA的调度式MAC协议的差异。针对原有TDMA MAC协议数据传输量不高、实现难度大等问题，提出相应的改进方法，并对三个基于LEACH的TDMA MAC协议进行了仿真实现，仿真结果与数据分析的结果一致。
