摘要
在分析现有蓝牙Adhoc网轮询方案的基础上,分别提出一种基于传统轮询方案中的DRR(Deficit Round Robin)算法的改进方案——WDRR(Weighted Deficit Round Robin)算法和一种基于自适应轮询方案中的LWRR(Limitedand Weighted Round Robin)策略的改进方案,并对WDRR算法进行了仿真。结果表明WDRR降低了网络的平均时延,在一定程度上改善了蓝牙Adhoc网的通信质量。
Current researches on polling schemes of Bluetooth Ad hoc network were briefly discussed. Other two improved schemes (one based on DRR, the other based on LWRR) were also proposed. The simulation results show that the WDRR algorithm outperforms DRR on the average time delay of the network and the quality of the Bluetooth Ad hoc network improves to some extent.
