摘要 提出一种基于动态占空比的流量自适应MAC协议,在基于S-MAC和TDMA流量自适应MAC协议的基础上,引入动态占空比机制,将原S-MAC协议的侦听/睡眠周期划分为多个短侦听/睡眠周期以实现多次数据传输。仿真结果表明,该协议在多竞争节点情况下能减少系统时延,维持较高的吞吐率,实现协议的平滑切换。 This paper gives an traffic-adaptive MAC protocol based on dynamic duty cycle.Based on S-MAC and TDMA traffic-adaptive MAC protocol,it introduces the dynamic duty cycle mechanism,the original listening/sleep cycle of S-MAC protocol is divided into several short listening/sleep cycles to transmit data repeatedly.Simulation results show that the protocol can effectively lower system delay,maintain higher throughput and achieve smooth switch of protocols when the number of contenders changes.
