摘要
采用多个无线中继节点接力组成线型链路的关键是中继节点的配置问题.文章分析了等距离、等RSSI和等丢包率3种经典的中继节点配置算法,提出了综合考虑距离、RSSI和丢包率的RSSI-PLR算法.通过仿真比较证明,RSSI-PLR算法能在节点数量受限时,保证两个端节点之间的距离和丢包率达到最优要求.
The key issue with utilizing multiple wireless relay nodes to make up a linear link is the allo cation of the nodes. This paper analyzes three classic allocation algorithms for relay nodes： equidistance al gorithm, equivalent RSSI algorithm, and equivalent packet loss ratio algorithm. Then the RSSI-PLR algo rithm that takes accounts of the distance, RSSI and packet loss ratio is proposed. Simulation and eompari son show that RSSI-PLR algorithm could guarantee the distance between two nodes and the packet loss ra rio are optimal when the nodes number is limited.
