An enhanced routing protocol for 802.11s-LTE communications

Nowadays, the LTE and WiFi networks are set to dominate the outdoor and indoor spaces. To enlarge the coverage of WiFi hotspots, a WMN: Wireless Mesh Network called IEEE 802.11s was defined. In this paper, we aim to enhance the interworking performance between LTE and 802.11s network by handling the QoS in IEEE 802.11s network. In this context, we improve the routing process of HWMP: Hybrid Wireless Mesh Protocol defined by the IEEE 802.11s standard by taking into account different QoS classes. A multipath routing process is considered to provide the fair allocation of traffic among different paths. The routing metric defined by the IEEE 802.11s standard was also modified to get more accurate information about the path quality. The proposed contribution is suggested as an enhancement to the HWMP protocol. It aims to provide better performance to the 802.11s-LTE communications. A simulation study under NS3 will be conducted in this paper in order to compare the performance of our contribution to HWMP.
