Control the Interval Estimation to Enhance the Performance of Optimized Link State Routing

This paper investigates the creation of self-organizing Mobile Ad hoc Networks (MANETs) employing Optimized Link State Routing Protocol (OLSR) with Multipoint Relay (MPR). The routing protocol in MANET controls the management of node mobility by using metrics to evaluate the quality of link states. The primary concept of OLSR is to choose the MPR that identifies the route from the source to the destination node. The MPR relays Hello and Topology Control (TC) messages between nodes used to discover and distribute link state information. The Hello and TC messages interval plays a critical role in the link state in the network. Accordingly, link failure for a few seconds may lead to a significant performance deterioration. This work enhances the performance of OLSR by estimating the efficient Hello and TC message interval for faster route recovery. Many experiments are simulated and analyzed by a set of parameters such as MPR count, TC traffic sent, throughput, delay, and data dropped. All our results revealed that the proposed Control of the Interval Estimation-Optimized Link State Routing (CIE-OLSR) has better performance than the traditional OLSR.
