为了提高WLAN中组播组吞吐量,节约网络带宽,保证组播接收端整体公平性效用,提出一种组播优化分组算法。将数据获取能力和信号质量相近的终端分到一组,研究不同分组数目下公平性效用值,并分析组播组吞吐量和网络带宽占用情况。实验结果表明在最佳分组范围内,整体公平性效用值增长率变大,吞吐量和带宽占用情况比RMM ( Receivers Merging Method)算法优,性能在组播转单播和直接组播传输之间达到很好的折中。

In order to improve the multicast group throughput of WLAN,reduce the network bandwidth and ensure the multicast receiver fairness,the multicast optimization grouping algorithm is put forward in this paper. Then take the ability of data acquisition and signal ter-minal into a group of similar mass,to research and analyze the fairness utility value,the multicast group throughput and network band-width usage under different number of grouping. The experimental results show that within the optimal grouping scope,the growth rate of overall fairness value is increased,the throughput is improved and the bandwidth is smaller than RMM,and the performance achieves a good compromise between multicast to unicast and multicast transmission.
