QoS aware routing protocol to improve route maintenance in Mobile Ad-Hoc Networks

Mobile Ad-hoc network (MANET) is an autonomous system of mobile nodes/devices connected by wireless links. These mobile nodes are free to move anywhere in the network without any centralized control. Multimedia applications are gaining great popularity in MANETs as these networked and portable devices are becoming more powerful and more multimedia enhanced. These type of applications define a new set of requirements in which they operate put together called as Quality of Service (QoS). Hence, it is desired to discover an optimal path including QoS parameters like delay, etc to enable better performance of multimedia applications. This paper focuses on improving route maintenance for QoS in MANETs. The ad-hoc on-demand distance vector (AODV) routing protocol is modified to provide QoS in terms of end-to-end delay and also aims to minimize the modifications to the protocol.
