Cooperation is an emerging paradigm for improving the spatial differentiations in Vehicular Ad-Hoc Networks (VANET). Cooperative communication systems can improve the performance and spatial diversity equivalent to the multiantenna systems like Multiple-Input Multiple-Output (MIMO) systems. Additionally, these systems are more realistic for the implementation with conventional limited resources and distributed hardware. Hence, many network solutions are motivated through the cooperative communications for boosting VANET efficiency regarding specific network constraints like energy efficiency, network capacity, and outage probability. As several effective studies are discussed about VANETs integrated with cooperative communications, it suffers from some basic problems, which does not explicitly utilize. The main goal of this article is to design & develop an optimization method for selecting the minimum number of multi-hops between source and destination for the cooperative VANET network. The first phase has first time slot, where a signal is transmitted by source to the cooperative nodes (its relays) and to their equivalent destination. The main problem considered here is to optimally select the number of hops or relays that to be adaptable for communication, with the intention of solving the multi-objective function concerning with the target throughput and outage probability. The adoption of new Dimension-based Cat Swarm Optimization (D-CSO) is the main contribution here to optimally select the multi-hops among source and destination. Through the performance evaluation, it is observed that the designed model has achieved network-wide fairness performance and good convergence rate.

“…With well-designed algorithm for path selection and relay selection, our approach can more effectively exploit the resources of cooperative vehicles to achieve high cooperative gain when the number of vehicles is large. At traffic density 120, compared with the CACA [31], AORS [39], and Coop V2V [41] approaches, our approach improves the aggregate throughput of the network by 240%, 225% and 150% respectively.…”

Routing is the key issue for Vehicular Networks since each node in the network has mobility. Dynamic nature of vehicular networks increases with the mobility and the consequence is reflected over control traffic overhead. As a result, the routing technique and the type of node mobility information are completely dependent on building dependable end-to-end communication links. To address these challenges, a Reliable Cluster based Multi Hop Cooperative Routing (RCCR) strategy was proposed by using velocity, distance and link quality parameters. This algorithm obtains the tradeoff between Quality of Service (QoS) and mobility constraints over link parameters. It improves routing scalability by electing cluster-heads and selecting Multi-Point Relays (MPRs) while considering mobility constraints and QoS needs. The proposed technique determines the link quality for every pair of nodes based on values of signal strength and distance parameters. The relay vehicles are chosen based on the highest possible QoS value, which is calculated to assure route stability, reliability, and durability. The heuristic limitations of the multi-point relay selection strategy are handled by considering the link quality, distance from source vehicle, and cluster-head coverage area to enhance the Packet Delivery Ratio (PDR) of multi-hop network with tolerable End-to-End transmission delay. Further, we optimize and obtained optimal number of cooperative vehicles in every hop with the objective to minimize the end-to-end energy consumption. Finally, simulation results demonstrate the effectiveness of proposed algorithm compared to other state of art algorithms.
