Overview and Challenges of Multi-Interface and Multi-Channel Multi-Hop Wireless Networks
Carine Toham, François Jan · IGI Global eBooks · 2010
The throughput improvement problem in wireless networks is considered. The main causes of that issue is the shared wireless medium and node spatial problems which either prevent some nodes from transmitting or jam their transmissions. We consider the use of both nodes equipped with multiple network cards and multiple channels as means to improve the throughput in wireless networks. That approach implies to handle some challenges namely channel distribution between the node interfaces and routing in such channel-diverse networks. This chapter analyzes some solutions proposed to deal with these challenges so that the throughput is improved. Some possible orientations are also discussed based on the advantages and drawbacks observed in existing works.
