一种新颖的无线传感器网络的MAC协议

A Novel MAC Protocol for Wireless Sensor Networks

通过对MAC协议运行原理、具有的优缺点、目前所存在的问题以及网络中信道接入机制和能效问题进行分析的基础上,给出一种侦听/睡眠和CDMA相结合的混合MAC协议,此协议采用周期性侦听/睡眠机制和CDMA技术来保证数据的流畅传输,从而实现能量的有效利用。最后,利用仿真软件NS2证明新方法的优越性和高效性。

This article presents a mixed MAC protocols combining listen/sleep mechanism and CDMA through analyzing MAC protocols operating principle, strengths and weaknesses, the existing problems, network channel access mechanism and efficiency. The protocols use periodic listen/sleep mechanism CDMA technique to ensure data smooth transmission, so as to realize the effective utilization of energy. Finally, NS2 is used to prove the superiority and high efficiency of the new method.
