Towards Developing Enhanced Cluster-Based QoS-Aware Routing in MANET

Creating dynamic communication infrastructures between mobile devices and satisfying the desires for time-sensitive multimedia applications have introduced new challenges in the design of protocols for mobile ad hoc networks. In this paper, to stream time-sensitive applications using mobile ad hoc network (MANET), we have selected the Optimal Link State Routing (OLSR) protocol. However, the protocol has high overhead because each node selects a set of multipoint relay (MPR) nodes. Therefore, we have proposed quality of service (QoS) supporting the MPR selection approach and a new lower maintenance clustering approach for minimizing the overhead of the network. As a result, the proposed approach showed a better result in the average end-to-end delay, packet delivery ratio, routing load, and throughput
