| 摘 要： | 针对占空比MAC协议存在端到端传输延迟问题，提出一种新的占空比MAC协议——PRMAC。PRMAC通过跨层路由信息帧的提前传送可以调度数据包在一个周期内多跳传输，从而降低网络延迟，提高能量有效性。NS-2仿真结果表明，PRMAC在没有牺牲能量有效性的情况下，改进了传统占空比协议的端到端传输延迟，并能提高网络吞吐量。

| Abstract: | The duty-cycle protocols exists significant end-to-end delivery latency.In order to solve this problem, a new duty-cycle MAC protocol named PRMAC is proposed.PRMAC can delivery a packet multiple hops in a period based on cross-layer routing information advanced transmission, thus reduce network latency and improve energy efficiency.Simulation result in NS-2 shows that PRMAC can improve end-to-end delivery delay and throughput in traditional duty-cycle protocol without reducing energy efficiency. |
