Nan Jian-guo · Jisuanji gongcheng · 2009
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.
