A Priority Based Dynamic DSR Protocol for Avoiding Congestion Based Issues for Attaining Qos in MANETS

The enhancement of Quality of Service (QoS) is the emerging domain in mobile and ad-hoc networks with various routing protocols. However, most routing protocols fail to support the network requirements as the resources are limited and lead to congestion in the networks because of multiple routes. Hence, the infrastructure-less architectures of mobile communications require a new set of strategies for improving the QoS factors. This paper proposes a priority-based mechanism in the DSR routing protocol for enhancing the QoS for the MANETs. In the experimentation, ten different communications are considered, and several performance parameters of the network, such as throughput, end-to-end delay, and packet delivery, are measured. They are compared against the traditional DSR protocol. From the simulation of experiments and comparison, we observed that the proposed model has significantly reduced the network’s delay and increased throughput in the network.
