Interference-aware multi-path routing and bandwidth allocation for mobile wireless networks
Xu-Zhen, Huang-Chuan He, Hu-Xian Zhi · 2008
Wireless interference can make a significant impact on the performance of a wireless network. The paper studies TDMA-based timeslot allocation to schedule links efficiently under RTS/CTS interference model of wireless networks, and presents an efficient distributed timeslot assignment algorithm. In addition, the paper presents an effective heuristic algorithm for calculating end-to-end bandwidth on a path, which is used together with AODV to setup multi-path QoS routes. Simulation results show that compared with the shortest path routing, our interference-aware QoS routing algorithm increases network throughout, request success ratio and packet delivery ratio, and reduce end-to-end average packet delay.
