X-MAC:A New MAC Protocol For Wireless Sensor Network
Ping Yi · Communications technology · 2013
With the explosive development of wireless sensor network,MAC(medium access control) protocol in the wireless sensor network system structure becomes an even more important protocol in ensuring the efficient communication.Wireless sensor network is significantly different in characteristics and technical requirements from the traditional wireless network.For many MAC-layer protocols,throughput is heavily limited by physical channel utilization and protocol overhead.Based on one-to-multiple topology and link quality,a MAC-layer protocol for wireless sensor network is proposed and designed.Finally simulation with NS-2(Network Simulator 2) is done,and the network performance comparison of the newly-proposed MAC-layer protocol with the existing MAC-layer protocol also made.
