Vehicular Network Dynamic Grouping Scheme

Abstract

Vehicular network (VN) has been a significant field of study in the field of wirelessly connected mobile objects. The high speed and significant dynamic in vehicular behavior on the road urge the need for rapid information flow for managing important events. On a highway road, for example, group of vehicles may stay connected for significant amount of journey time. Some vehicles may depart, and new ones may join. The variance in speed makes the physical location within the group dynamically changing. Herein, the flow of data under various dynamic changes that can be realized through a manageable network design promotes the need for a road related vehicular grouping approach. This as part of vehicular connectivity is a promising approach for managing the road dynamics awareness and network of vehicles connectivity efficiently. Dynamically, the road could accommodate numerous vehicular networks. Each of these networks has a given lifetime from the initial formulation to the final dimension. Throughout this life cycle, a large-enough vehicular group form a network. Vehicles leaving the group may rupture the data network and cause isolation of part of the network that raises the need for healing. Reaction to these dynamics may cause latency in data flow and requires efficient operation with minimal latency. Such network demands high degree of flexibility with effective real time computational capabilities and autonomous self-structure mechanism. The research focuses on the development of grouping process and related variance throughout the group life cycle as influenced by the road dynamics. Example development of the key processes of self-organized, self-healing, and members joining and leaving is discussed.
