Utilization of nested clustering in VANET to reduce data loss in mobile cloud computing

Abstract

Over the recent few years, most of network service providers have tried to expand their services all around by newly emerged technologies in network, especially mobile cloud computing. Most emerging cars and vehicles with powerful computers and storages, can be equipped with such new technologies such as vehicular ad hoc network radio, a new wireless technology. These capabilities lead network service providers to use these potentials to expand their network services such as Internet on the roads. It seems there are enough materials and peripherals to design a convenient network but every new architecture will have its limitations and problems, such as data loss, in performance. In this paper at first, we propose a design to find a proper cluster head in a group of vehicles. Then, based on some mathematical and physical methods and criteria, we demonstrate that nested clustering can reduce data loss in real streets and at equipped traffic-light crossroads, noticeably. Finally, we perform the simulation experiments to demonstrate the efficiency of our proposed approach in comparison with other approaches.

Beetle colony optimization algorithm‐based node clustering scheme for efficient data dissemination in vehicular ad hoc networks

“…Furthermore, the beetle keeps moving for a length of "d t " along a direction wherein the fitness is improved. With an increase in the number of iterations, "d" and "δ" decrease slowly as mentioned in Equations ( 11) and (12).…”

“…Hence, ideal and suitable nodes need to be selected as CHs for guaranteeing a stable cluster that aids in attaining network stability. 12 Diverse procedures incorporate various solutions that reliably depend on the size of the clusters which eventually helps in determining the vehicular nodes' range. Likewise, nodes of the cluster modify their selected CH with time as vehicles travel on the road.…”

“…Thus, cluster stability needs to be attained when there is no frequent change in the selection of cluster head (CH) or re‐clustering process in the network. Hence, ideal and suitable nodes need to be selected as CHs for guaranteeing a stable cluster that aids in attaining network stability 12 . Diverse procedures incorporate various solutions that reliably depend on the size of the clusters which eventually helps in determining the vehicular nodes' range.…”
