Improving Stability and Efficiency in MANETs: A Multi-Criteria Approach for Optimal Multipoint Relay Selection

Abstract

Mobile ad hoc networks (MANETs) were self-sufficient networks made up of several nodes on the move that could connect electronically without the aid of any kind of pre-existing equipment. Because such networks function in extremely unpredictable situations, their capacity to ensure. Mobile area networks, or MANETs, constitute distributed networks with nodes that roam. Energy is a crucial resource because MANET nodes are battery-operated.  In OLSR, MPRs are separate nodes to which various nodes decide to send information and manage traffic. As a result, MPR nodes may consume a significant amount of power. Providing Quality of Service (QoS) is a significant research challenge since those networks are susceptible to volatility brought on by wireless communication nor movement. Therefore, when creating routing techniques for MANETs, it is essential to use circuits and mediation facilities that provide assurance, safety, and longer network lives. In order to address the issues of node mobility, energy limitations, and security flaws, this study suggests an advanced algorithm for choosing complicated messengers (MPRs) in MANETs. The suggested method improves networking strength, availability, and endurance by using a multicriteria-weighted methodology that evaluates the dependability, energy consumption, and range of portable nodes. The enhanced technique is tested in NS5 simulations using its Random Waypoint as well as ManhattanGrid motion models. According to the results, the improved algorithm performs better than the conventional OLSR, especially when it comes to throughput, messages distribution, and latency decreases for changeable network situations.
