Multipath Routing Protocol for MANET Using Hybrid Optimization Approach to Support QoS

MANETs are infrastructure-less networks consisting of mobile nodes that form temporary networks. Ensuring Quality of Service (QoS) in MANETs is challenging due to mobility and limited resources. This research proposes a multipath routing protocol prioritizing QoS support to address dynamic network conditions and limited bandwidth. The protocol aims to enhance QoS provisioning in MANETs for efficient and reliable real-time data delivery. In this paper, an Optimization-Based Energy-Efficient Demand Multipath Routing Protocol (OEDMRP) is proposed for Mobile Ad hoc Networks (MANETs). The protocol combines optimal cluster formation and routing protocol optimization using hybrid optimization techniques. By forming clusters of unequal sizes and dynamically adjusting routing parameters, the protocol aims to optimize energy consumption and ensure reliable communication in MANETs. The result was evaluated in terms of end-to-end delay, packet delivery ratio, throughput, and energy consumption. The result was also compared with existing state-of-art and outperforms better.
