A Weighted Control Dynamic Clustering Approach in Vehicular Adhoc Network

Abstract: VANETs have been appeared as a new area of data dissemination process in which vehicles provide aid to the end users. Vehicles in vehicular ad hoc network have highly unstable (dynamic) topology which produces hindrances in timely delivery of sensitive messages. The best panacea to stabilize the highly unstable networks is clustering process. Unfortunately stable clustering does not minimize the overhead of cluster reorganization to great extent. Thus to tackle the overhead problem of cluster reorganization process, dynamic clustering is an effective way. In this paper, dynamic clustering is proposed and cluster head is defined on weighted control factor and further the cluster reorganization process is minimized by calculating NACH (next available cluster head) factor.

Keywords: vehicular ad hoc network (VANETs), cluster head (CH), NACH.
