Abstract
A revolutionary concept for enhancing the geographical differentiations in vehicular ad hoc networks (VANET) is cooperation. Similar to multi-antenna systems such as Multiple-Input Multiple-Output (MIMO) systems, cooperative communication systems may enhance performance and geographical diversity. These systems are also easier to develop with dispersed hardware and traditionally constrained resources. In order to boost VANET efficiency with regard to certain network restrictions like energy efficiency (EE), network capacity (NC), and outage probability (OP), more network solutions are inspired by cooperative communication despite the fact that various successful research on VANET coupled with cooperative communications is mentioned, they have certain basic issues that they do not clearly address. This article primary goal is to develop and suggest an optimization technique for choosing the fewest possible multi-hops among source and destination for a cooperative VANET. The signal is transferred from the source to the cooperating nodes (their relays) and to their comparable destination during the first time slot of the first phase. In order to solve a multi-objective function including goal throughput and OP, how to choose the ideal amount of relays or hops to allow for flexible communication is the main problem being tackled here. The selection of the best source and destination multi-hop is significantly aided by the use of the novel Dimension-based Cat Swarm Optimization (D-CSO). The suggested model was shown to have a reasonable convergence rate and a fair performance over the whole network via the performance assessment.
