On supporting reliable QoS in multi-hop multi-rate mobile ad hoc networks
Due to complicated situations such as node/link interference and traffic load, quality of service support in multi-hop multi-rate ad hoc networks remains a challenging issue. Furthermore, when mobility is present, because of frequent route change, it is even more difficult to maintain high level performance for existing real-time flows that may not tolerate serious performance degradation. In this paper, we focus on the issue of providing sufficient QoS in networks with moderate to high node mobility. We first introduce route available bandwidth (RAB), a major index for prediction of flow performance along a specific path. RAB considers various important factors such as intra-flow interference, effective link bandwidth, and channel busy time. Then, we devise a DSR based admission control scheme where the source node accepts/rejects a flow according to the RAB of the collected route when it receives a route reply packet. To handle mobility, we incorporate an additional metric o...
