摘要 在流量自适应媒体访问控制(MAC)协议中,容易产生吞吐量抖动的问题。为此,提出一种动态占空比机制的改进方案。在基于S-MAC和TDMA流量自适应MAC协议基础上,通过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。NS2仿真结果表明,该方案能减少系统时延和能量消耗,同时维持较高的吞吐量,实现协议的平滑切换。 Aiming at the disadvantage of traffic-adaptive Media Access Control(MAC) Protocol,this paper gives an improved scheme of dynamic duty cycle mechanism.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.NS2 simulation results show that the improved protocol can effectively lower system delay and power consumption,maintain higher throughput and achieve smooth switch of protocols.
