Abstract :
Quality of Service (QoS) support has been well studied as a hotspot in mobile ad hoc network. However, since interference range is much larger than transmission range, estimating available bandwidth at each node remains a challenge. To address this problem, a novel Event-driven Bandwidth Estimation Method (EBEM) is proposed in this paper. By incorporating a comprehensive intra-flow interference predicting approach and an event-driven inter-flow collision detecting strategy, EBEM could estimate nodal available bandwidth substantially, preventing the network from being overloaded. Results from simulation verify that EBEM not only surpasses typical AODV protocol in both end-to-end delay and packet delivery rate, but it also outperforms latest QAR method in both total throughput and packet delivery rate. As such, EBEM can be applied to various QoS routing protocols to estimate nodal available bandwidth.
