RETRACTED ARTICLE: EE-FMDRP: energy efficient-fast message distribution routing protocol for vehicular ad-hoc networks

Abstract

Vehicular ad-hoc network (VANET) is a promising communication framework that provides connectivity between vehicles via vehicle-to-RSU (road side unit), inter-RSU and inter-vehicle communications and is features by high dynamic topological formation of nodes in the network. In VANET, the message distribution delay and reliable communication are the significant factors in case of emergency based communications. The main contribution of this paper relies on reducing message distribution delay with minimal communication overhead. Moreover, energy efficient-fast message distribution routing protocol (EE-FMDRP) has been proposed with the collaborative features of both time and direction oriented routing models. It has been proposed for broadcasting messages in case of emergencies from the source end to the defined target in fast, reliable and efficient manner. For that, bi-directional evaluation model for moving vehicles and message delivery time derivation model has been framed. This helps in performing fast message broadcasting in emergency cases with maximal throughput and reduced delay. Also, the EE-FMDRP offers consistent and efficient route between source vehicle and the destination with optimal intermediates and reduced complexities. Further, the protocol takes less message distribution time by selecting optimal intermediates, thereby providing energy efficiency and minimized network overhead. For evaluation, NS-2 simulation tool is used and the results prove that the proposed model achieves improved results than the compared existing protocols.
