CHANNEL ASSIGNMENT IN WMNS: ISSUES AND SOLUTIONS

Wireless Mesh Networks (WMNs) are recently gaining much attention due to the scope for increasing aggregate network throughput by utilization of non-overlapping channels. In this context, Channel Assignment (CA) is a key issue in offering optimal performance multi-radio multi-channel WMNs. A good CA scheme can maximize number of simultaneous transmissions, which in turn maximizes aggregate network throughput. In this paper we address key issues in designing CA Algorithms for multi-channel multi-hop networks. We classify various state-of-the-art Channel Assignment Schemes and present a comparative analysis. Some future research directions for CA are also suggested.
