The attractiveness of Wireless Mesh Networks (WMNs), in general, can be attributed to their ability to dynamically self-organize and self-configure, coupled with the ability to maintain mesh connectivity, resulting in low cost installation set-up, simpler maintenance tasks, and service coverage with high reliability and fault-tolerance. As a result, WMNs have found many useful applications in a broad range of domains. In this paper, we discuss the need for adaptive and dynamic routing protocols in WMNs and discussed several existing approaches for adaptive routing protocols. We also identify the different parameters in traditional wireless routing protocols (and their variants) and provide a qualitative review of their impact on network performance when adapted to changes in network characteristics. We include our initial finding in simulation scenario to investigate the relationship of important parameter with respect to mobility. A comparison of existing adaptive WMNs protocols are also presented in this paper.
