Zebra MAC协议的改进研究

Study on improvement of Zebra MAC protocol

ZMAC协议是一种混合型MAC协议,吸取了分配型和竞争型的优点,是一种非常好的MAC协议。MAC协议首要解决的就是能量消耗问题,而ZMAC考虑到的能量消耗问题不够。文章在ZMAC协议的基础上引入了睡眠机制来降低能量消耗,改进了ZMAC协议在低冲突级别的发送方式,在自己的局部时隙可直接发送。

ZMAC protocol is a hybrid MAC protocol, which absorbs the advantages of allocation and competition. It is a very good MAC protocol. The first problem to be solved in MAC protocol is energy consumption, which is not enough in ZMAC. On the basis of ZMAC protocol, this paper introduces sleep mechanism to reduce energy consumption, and improve the transmission mode of ZMAC protocol at low conflict level, which can be sent directly in its own local slot.
