Wireless Mesh Networks WMNs have emerged as a key technology for next generation wireless networking WMNs are undergoing rapid progress and inspiring numerous applications because of their advantages over other wireless networks Due to heterogeneous and fluctuating wireless link conditions preserving the required performance of such WMNs is still a challenging problem For example some links of a WMN may experience significant channel interference from other coexisting wireless networks Links in a certain area might not be able to use some frequency channels because of spectrum etiquette or regulation newlineA wireless mesh network can be seen as a special type of wireless ad hoc network A wireless mesh network often has a more planned configuration and may be deployed to provide dynamic and cost effective connectivity over a certain geographic area Multi hop wireless mesh networks experience frequent link failures caused by channel interference dynamic obstacles and or applications on bandwidth demands These failures cause severe performance degradation in WMNs or require expensive manual network management for their real time recovery newline%%%appendix p101-102, reference p103-109.
