The QoS performance improvement in AVAODV routing protocol

The proposed routing protocol BQAODV considers link stability, available bandwidth estimation, direction conformity and delay constraint based on AVAODV routing protocol. It selects a highest link stability route which meets available bandwidth, direction conformity and delay constraint during the search for a new route. The simulation results show that BQAODV's data packet loss rate and average end-to-end packet delay performance are better compared with AVAODV, and there is almost no difference between BQAODV's and AVAODV's average routing overhead especially under certain dynamic environment in MANET.
