Research of QoS routing protocol based on delay for wireless Mesh networks

As a key technology for next-generation wireless networking, wireless mesh networks (WMNs) should support the quality of service (QoS) because of providing various services. In order to satisfy the delay requirements of services in the WMN, this paper puts forward a QoS routing protocol which fit for the WMN—QoS-AODV. Under the premise of the delay being in the range of QoS demands, it combines the features of AODV algorithm and defines the new route metric with the hop count and load rate for providing different QoS guarantees of real-time multimedia services and non-real-time text service. The analysis and the simulation result indicated that QAODV performs better than AODV and AODV-D on thee aspects of reducing the delay and enhancing the real-time performance with small increase of control overhead. So the protocol achieved the goal of enhancing QoS of wireless Mesh network.
