A survey of routing and channel assignment in multi-channel multi-radio WMNs.

Wireless mesh networks provide cost-effective coverage and high network performance by utilising advanced radio frequency technology such as multiple channel multiple radio (MCMR). In spite of the advantages in MCMR wireless mesh networks, some wireless mesh networks still suffer from performance issues such as throughput degradation and unacceptable latency when network size increases. Existing studies focused on solving the performance issues from a single aspect such as routing or channel assignment. A major limitation of these studies is its failure to consider the interaction between routing and channel assignment which is a key factor influencing network performance.
