Improvement of AODV Routing Protocol in Mobile Ad Hoc Netwoks

Mobile Ad Hoc network is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of preestablished network infrastructure.Because of the necessary of such as military affairs and disaster rescuing,mobile Ad hoc routing protocol becomes one of hotspots of research.But the improved algorithems of AODV are complex and difficult to implement and can't provide the guarantee of quality.A QoS routing protocol which algorithm is easy is proposed based on AODV,which provides node-disjoint mutipath routing.Its QoS parameter is bandwidth.The performance via simulations shows that it is better than AODV in packet delivery ratio,average delay and routing cost.
