A Method Based on ARQ for Handling Congestion in Wireless Networks |
|
() |
Abstract: |
This paper develops a congestion control method for wireless networks based on multi-reject ARQ algorithm. According to RED(Random Early Detection) algorithm, this method controls the congestion through the ARQ sending window, the length of segmentation queue and the link-layer retransmission rate. The simulation proves this method can improve the link throughput. |
