摘要
针对不同的传感器网络应用,研究人员从不同方面提出多个无线传感器网络介质访问控制(MAC)协议,其中包括S-MAC,PMAC,DEANA,EMACs,Z-MAC以及AIMRP等协议。通过分析各类MAC典型协议特点,归纳其设计原则和分类方法,比较各协议间的性能差异,结果证明无线传感器网络MAC协议呈现多样性的特点,设计MAC协议需要兼顾能量效能和网络性能2个方面。给出MAC协议的设计策略。
Many new Medium Access Control(MAC) protocols have been designed according to different applications, including the S-MAC, PMAC, DEANA, EMACs, Z-MAC and AIMRP protocols. This paper analyzes characteristics and performance of various typical MAC protocols. Design principles and classification methods for MAC protocols are summarized and compared in detail. Results show that a good MAC protocol is that it has the ability to make tradeoffs between energy-efficiency and other performances of WSNs in term of application conditions. According to the same principles, the future devisable tactics of MAC protocols in WSNs are pointed out.
