A bandwidth management approach for quality of service support in mobile ad hoc networks

Bandwidth management is a key feature for providing quality of service (QoS) in contemporary mobile ad hoc networks (MANETs). In this paper, we present a novel approach to bandwidth reservation which is designed for highly mobile environments. In this scheme, a node takes into account the bandwidth requirements of its 2-hop neighbors. The design of this scheme does not depend on any routing protocol. We evaluate the proposed approach by incorporating it in the well known AODV protocol. The comparison between the original AODV and its extended version, with our approach, shows that the latter achieves a significantly lower latency and higher reliability.
