Energy-efficient MAC protocol of three layers virtual cluster
Xiaomin Zhang · Computer Engineering and Applications Journal · 2009
Because the sensor node can not power themselves or can not power enough,the energy-efficient should be consid- ered first when a MAC protocol is presented,but for the traditional wireless networks the network-efficient is first.This means the MAC protocol for traditional wireless networks is not adapt to the wireless sensor networks.So new MAC protocols for wireless sensor networks must be researched.This article compares many MAC protocols that have been presented,and researches the E-BRI-MAC particularly,to make some improvements,present TLVC-MAC is presented,in which,an idea of three layers virtual cluster based on data deliveries is proposed in order to save energy and improve the energy-efficient.
