Improved QoS scheme based on SWAN model in wireless Ad hoc network
Nana Li · Journal of Jilin University · 2010
To enhance the QoS performance of the stateless wireless Ad hoc network(SWAN) model,its admission control scheme and routing protocol were improved. The saturated throughput of the 802.11 DCF protocal and the intra-flow interference model were analyzed and the estimation methods for the node available bandwidth and the real-time bandwidth consumption were proposed to improve the accuracy of the admission control scheme. Meanwhile,the traffic load imformation of the network was applied in the route discovery to select the more resourceful route for data transmission. The simulation results showed that the proposed schemes significantly improves the delay performance of the real-time traffic and the total throughput of the best effort traffic.
