Abstract

A realtime-flow-based QoS routing protocol is proposed in wireless ad hoc networks. The key idea of it is to estimate its neighbor available bandwidth through exchanging the information about consumed bandwidth of realtime flows and its local available bandwidth with the other nodes which are located in the node's wireless carrier sensing area, execute route discovery and admission control for a new realtime flow based on a node s neighbor available bandwidth, and reserve resource based on the required bandwidth of the realtime flow. Constructing a route for each realtime flow favors avoiding the contention among the realtime flows which have the same source and destination address, which makes network load achieve load balance. Simulation shows that the proposed realtime-flow-based QoS routing protocol can provide better QoS guarantee for realtime applications.
