Wireless Mesh networks have made it possible to have seamless connectivity in between the community users. WMN is a low cost network supporting multihop communication through a backbone like structure. But, to provide services like neighborhood and community network, broadband home network, building enterprise network QoS provisioning is very much essential. In this paper, the authors presented a comparative study of the three efficient QoS provisioning methodologies while presenting the requirement and challenges for QoS provisioning for Wireless Mesh Networks. Moreover, this paper also includes the key advantages of deploying Wireless Mesh Networks.
