Queue control based delay analysis and optimization for wireless mesh networks

Wireless mesh network is a key technology for next generation wireless networking. Delay is regarded as a critical component in networks quality of service (QoS) especially the real-time applications become increasingly popular in recent years. In this paper, the queue control system of multi-interface multi-channel (MIMC) wireless mesh networks (WMNs) is modeled firstly, then we analyse the average queueing delay and the average queueing length, and optimize the average queueing delay by more network interfaces as well as transmitting rate of sending interfaces. Finally analytical explanation and simulation using ns-2 simulator show that use ing MIMC strategy in high traffic loading node is a good approach to optimize network performance, the average queueing delay in nodes with dual-channel dual-interface that do not interfere with each other can be reduced by about 30% compared to the single-channel single-interface.
