QoS Multi-tree Based Routing Protocol for Inter-mesh Infrastructure Communications

Part 5: Network ProtocolsInternational audienceQuality of service (QoS) in wireless mesh networks (WMN) is an active area of research, which is driven by the increasing demand for real-time and multimedia applications, such as VoIP (Voice over IP) and VoD (Video on Demand). In this paper, we propose a QoS multi-tree based routing protocol for wireless mesh environments, named Inter-Mesh Infrastructure Proactive Routing (IMPR). It is a proactive multi-tree routing protocol enabling QoS guarantee for communications from/towards the Internet network through the Mesh Gateway (MG) of the mesh infrastructure. We describe and analyze the simulation results of different scenarios conducted on the network simulator ns-3 to demonstrate the effectiveness of our IMPR routing protocol in forwarding real-time applications with QoS guarantee
