Multipath Relay (MPR) Node Selection for Collision Avoidance and Efficient Routing in Mobile Ad Hoc Network

Abstract

Mobile Ad Hoc Network (MANET) are characterized by dynamic topologies, limited bandwidth, and the absence of centralized control, making reliable data transmission a significant challenge. The performance of the network is frequently deteriorated by collisions are concurrent transmissions and ineffective relay node selection. This research suggests a new method for choosing multipath relay nodes that minimises packet collisions and improves MANET overall routing efficiency.OS approach ensures optimal route diversity and low interference by dynamically assessing possible relay nodes using a composite measure that takes into account node mobility, residual energy, and link stability. The technique was compared to existing Multi Path Relay (MPR) selection algorithms through simulations using NS3.The experimental findings show that, under different network densities and mobility models, there is a significant decrease in end-to-end delay, an improvement in packet delivery ratio, and a greater throughput. These enhancements validate that the strategy is successful in preserving reliable and effective communication channels. The results possess significant implication for mission-critical and delay-sensitive MANET applications, including military communications and disaster recovery.
