Efficient Channel Allocation Techniques for Wireless Mesh Network

In order to improve network performances in WMN, a reliable and efficient channel allocation is needed. This paper focus on solving the channel allocation problem with a Rate-Based Channel Assignment (RB-CA) protocol to alleviate performance anomaly by using multiple channels in WMNs. RB-CA exploits a new metric, called Prioritized Transmission Time (PTT) and Load Traffic Count (LTC) , in order to form High-rate Multi-channel Paths (HMPs). Extensive NS-2 simulations and experiments in a real test-bed can be used to evaluate the performance of RB-CA. The simulation and experimental results can show that RB-CA achieves improved performance in terms of aggregate throughput, end-to-end delay, and energy.
