A QoS-aware multipath routing protocol for WiFi-based long distance mesh networks

摘要: Routing plays a crucial role in provisioning Quality of Service (QoS) over WiFi-based Long Distance (WiLD) mesh networks. Traditional routing protocols normally maintain single optimal path between each pair source and destination nodes. In gateway-based networks, the paths gateway other nodes often overlap hence degrades overall network performance significantly. Multipath are widely used Wireless Mess Networks (WMN) for providing QoS to various applications. Smooth real time traffic with varying requirements is challenging task. this paper, we propose QoS-aware hybrid multipath protocol which can discover multiple maximally disjoint any node. The node selects n-best Before starting given flow, selection scheme chooses appropriate or set amongst available discovered paths. To evenly distribute among chosen, an admission control mechanism has been proposed. case significant change quality paths, maintenance process induces trigger route update process. proposed enhances simulation results show that achieves improvement different parameters. With increase number from destination, substantial throughput delay observed.
