A novel TCP congestion control mechanism with QoS-guaranteed cross-layer optimization for wireless networks
Qian Wang, Dongfeng Yuan · 2009
Comparing to wired network, there are many different characteristics in wireless environments such as higher error rate, lower bandwidth, frequent mobility and so on, which result in difficulty to guarantee qualities of service (QoS). To improve TCP performances in wireless networks, we propose a novel TCP congestion control mechanism with QoS-guaranteed cross-layer optimization that can be easily implemented with fewer overheads. The simulation results demonstrate that our scheme can effectively improve reliability with small variances of throughput and delay and greatly guarantee end to end QoS requirements.
