Ad Hoc On-Demand QoS Routing Based on Bandwidth Prediction(AQBP)

This article mainly describes the Ad hoc on-demand QoS routing based on Bandwidth Prediction (AQBP). Differing from the existing QoS routing protocols, AQBP takes node future bandwidth into consideration when selects route. The future bandwidth requirement of each node is predicted by its history. The performances of throughput, transmission ratio and delay among AODV, AQOR and AQBP have been simulated. Moreover, the results represent that AQBP reduces the possibility of route change during the transmission, thus performs a higher throughput than its counterpart AQOR especially when network is busy.
