Perfor mance of a QoS-based multiple-route ad hoc on-demand distance vector protocol for mobile ad hoc networks

This paper proposes a quality of service based multiple-route ad hoc on-demand distance vector (QoS-MRAODV) routing protocol for achieving and maintaining QoS in mobile ad hoc networks (MANETs). The QoS-MRAODV protocol supports one active QoS-based primary route and several backup routes to provide hot standby redundancy against frequent route failures that are prevalent in MANETs. Results from extensive performance simulation of the QoS-MRAODV protocol demonstrate that it is indeed a viable protocol for achieving and maintaining QoS support in MANETs, providing the additional benefits of fast route discovery time and low routing overhead without a significant increase in end-to-end packet delay.
