| 摘 要： | 差错控制是无线传感网中的重要问题,基于能量效率和误帧率两个性能指标,对链路层采用ARQ、物理层采用FEC的联合差错控制机制（ARQ＋FEC）进行了数学分析和性能仿真。仿真结果表明：信道误比特率大于拐点时,ARQ＋FEC是可行的差错控制方案。仿真还显示了有效负载长度及纠错能力对于ARQ＋FEC性能的影响。

| Abstract: | Error control is an important issue in wireless sensor networks.This paper presents comprehensive mathematical analysis and simulation of a multi-layer joint error control mechanism in wireless sensor networks,in terms of energy efficiency and error frame ratio.This multi-layer joint error control mechanism combines ARQ in the data link layer with FEC in the physical layer(short as ARQ+FEC).Simulation results show that ARQ+FEC is a feasible error control mechanism when channel error probability exceeds the ... |
