| 摘 要： | 针对无线传感器网络中的大多数协议要以牺牲时延为代价来节省能量的问题,提出了一种结合路由层和MAC层协议的新协议RMAC,并从理论上证明了该协议既能降低时延,又能节省能量.用NS2仿真器的仿真结果表明,该协议几乎能节省近一倍的时延,而且不论链路负荷如何,所耗能量都既少又稳定.

| Abstract: | A new protocol RMAC was presented,which integrated the routing and MAC layers protocol and both reduced the latency and saved energy in WSN while most proposed protocols have tradeoff between latency and energy.After theoretically proving the advantage of RMAC,it is shown that RMAC reduces almost half of the latency while costing much less energy compared with the traditional 2-layer protocol with NS-2. |
