EL-MAC Protocol for Wireless Sensor Network
Jifeng Sun, Zhichao Gu · 2008
EL-MAC, a contention-based MAC protocol, is proposed in this paper. EL-MAC is efficient and low-latency for the WSN. By cross-layer operating, nodes build the data forwarding chain (DFC) by contending means and staggered wake up in proper time so that packets could be duly forwarded as more hops as possible in a cycle and the latency decline greatly. The simulation results show that EL-MAC has lower latency and higher throughput with less energy consumption on the same environment condition than S-MAC.
