Abstract
Due to bandwidth constraint and highly dynamic topology in ad hoc network systems, one of the major challenges is the deployment of end-to-end quality-of service support mechanisms. Time-sensitive communications like video applications may be seriously disrupted if these QoS support mechanisms don’t exist. In this paper we propose a QoS routing protocol based on AODV (AQA-AODV), which creates routes according to application QoS requirements. We have introduced link and path available bandwidth estimation mechanisms and an adaptive scheme that can provide feedback to the source node about the current network state, to allow the application to appropriately adjust the transmission rate. The simulation results reveal the performance improvements in terms of packet loss and delay while the end-to-end throughput is not affected compared with the throughput achieved by other protocols like AODV.
