Abstract: Wireless mesh networks (WMNs) have emerged as a flexible and low-cost network infrastructure, where heterogeneous mesh routers managed by different users collaborate to extend the network coverage. IEEE 802.11s standard was defined as a wireless mesh network which extends IEEE 802.11 MAC standard. The protocols introduced by IEEE 802.11s draft are divided into Proactive, Reactive or Hybrid categories. This paper aims to improve the routing process of HWMP: Hybrid Wireless Mesh Protocol defined by IEEE 802.11s standard by interworking 802.11s network with LTE network. Also, it aims to make the protocol more reliable by providing the QoS to the network. The pre-defined path selection metric is also enhanced to get more accurate information about the path quality. The proposed contribution aims to provide better performance to the 802.11s-LTE network and enhances the network with delay-aware routing. A simulation study will be conducted under NS-3 to observe the impact of the proposed protocol in offloading mechanism. Finally, the performance of overall contribution is compared to HWMP.
