Abstract :
Energy efficiency is the kernel issue in the designing of wireless sensor network (WSN) MAC protocols. S-MAC is a WSN MAC protocol based on the listen and sleep mechanism to reduce energy consumption. Synchronous frame in S-MAC protocol belongs to control information, so it´s better to reduce it as much as possible. In addition, S-MAC protocol adopts virtual cluster synchronization mechanism which leads to the generation of border nodes, and the border nodes will exhaust energy more easily and earlier. This paper analyzed S-MAC, and proposed LO-MAC protocol. The LO-MAC protocol improved S-MAC by decreasing the control energy consumption and thus prolong network lifetime compared with S-MAC protocol, furthermore, it resolved the problem of border nodes. The simulation of S-MAC protocol and LO-MAC protocol energy efficient on NS2 improved that LO-MAC protocol was more energy efficient than S-MAC.
