This paper focuses on the two routing protocols proposed by IEEE 802.11s for Wireless Mesh Networks. Towards this goal, this paper contributes in several areas of Routing and Quality-of-Service provisioning in IEEE 802.11-based wireless mesh networks. It compares the variety of routing protocols that could be used for Wireless Mesh Networks and later we specially focus on the recommended routing protocols HWMP and RA-OLSR by IEEE 802.11. We simulated using ns3 simulator under various parameters and observed how the two protocols reacted with changes in these parameters. From these observations, we have been able to study and compare few QoS of the routing protocols of Wireless Mesh Networks.
