Which Vehicle To Select?

In wireless networking, an Opportunistic Bundle Release Mechanism (OBRM) is a data bundle forwarding mechanism characterized by its ability to operate over Intermittently Connected Networks (ICNs) where end-to-end paths are not continuously available. Known for their intrinsic connectivity intermittence, vehicular networks constitute an ideal recreation ground for OBRMs. This letter, proposes the Optimal Vehicle Selection OBRM (OVS-OBRM) with the objective of minimizing the average bundle delivery delay.

I. Introduction

Vehicular networking consists of transforming vehicles into intelligent mobile entities that wirelessly communicate with each other as well as with stationary roadside units (SRUs). Due to the random nature of vehicular mobility and the relatively high vehicle speeds, a vehicular network's topology becomes highly dynamic and prone to recurrent link intermittence. Hence, timely information delivery becomes a gruelling task, the realization of which intersects with several underlying challenges. This letter revolves aroundOpportunistic Bundle Forwarding Mechanisms(OBRMs) in the context of inter-SRU delay minimal information delivery. These have, thus far, received little attention and are further investigated herein. An OBRM is a bundle (i.e. message) forwarding mechanism where nodes are exploited as store-carry-forward devices whose forwarding decisions are exclusively based on the synchronic turns of events.
