Even though channel assignment has been studied for years, most IEEE 802.11-based multi-hop wireless networks such as WSN, WMN, MANET are limited by channel interference. Properly assigning orthogonal channels to wireless links can improve the throughput of multi-hop network. To solve the dynamic channel assignment problem, a routing-based channel assignment algorithm R-CA is proposed. R-CA can allocate...
In order to increase the network capacity and improve the network performance of wireless mesh networks (WMNs), a possible solution is to make the nodes equipped with multiple radios which tuned on multiple non-overlapping channels. Efficient channel assignment is necessary for throughput optimization of mesh nodes. This paper proposed a novel channel assignment algorithm which is very suitable for...
Wireless mesh networks (WMNs) support a variety of modulation and coding schemes (MCSs) and hence enable adaptive modulation and coding. On the one hand, adaptive modulation and coding significantly increases the overall system capacity, as it allows to maximize the throughput on each link in dependence of the channel conditions. On the other hand, there is a trade-off between link data rate and spatial...
