Design of QoS Routing Framework Based on OLSR Protocol

Mobile Ad-hoc Networks (MANET) is the self organizing collection of mobile nodes. The communication in MANET is done via a wireless media. In order to support the growing need for multimedia and real time applications, QoS support has become essential. However it is a challenge to route QoS in wireless environment due to node´s dynamic nature and mobility. This paper aims towards efficient QoS routing using OLSR (Optimized Link State Routing) by enhancing the MPR (Multi Point Relay) selection criteria. Considering the QoS parameters of effective bandwidth and end-to-end delay, a new algorithm has been proposed to map the QoS parameters into a single numeric weight in order to select the MPR node. The simulation results establish the efficiency of the proposed methodology.
