Abstract
In today’s world, Mobile Ad hoc Network (MANET) is spread across different areas of applications due to its distinct characteristics. With the popularity of multimedia applications over MANET, it is vital to provide Quality of Service (QoS) during data transmission. In MANET, due to frequent topological changes and limited resources, routing of data packets between multimedia devices is a very challenging task. Inefficient routing may lead to higher delay, more packet loss and less throughput. Therefore, for providing quality of service (QoS) for multimedia applications over MANETs, this paper proposes a QoS enabled routing protocol (QoSRP) which is obtained using AODV with some changes during route discovery operation. Modifications have been done in route request phase, route reply phase and during exchange of hello messages. Simulation pattern shows significant improvement in performance. On varying simulation time, the packet delivery ratio (PDR) of QoSRP is found to be 10.58% more over AODV and 8.5% over Mo-AODV. Similarly, throughput is 9.8% higher with respect to AODV and 7.29% over Mo-AODV. Likewise, the scheme shows 50% improvement in delay perforamce over AODV and 35.71% over Mo-AODV. The simulation is also performed by varying number of nodes and results show that the PDR of QoSRP is 10.29% more as compared to AODV and 8.87% over Mo-AODV. Similarly, the scheme acheives 10.88% more throughput with respect to AODV and 9.62% against Mo-AODV. Likewise, the scheme shows 50% improvement in delay perforamce over AODV and 33.33% with respect to Mo-AODV.
