Abstract

Nowadays, data dissemination using Road Side Units (RSUs) in Vehicular Ad Hoc Networks (VANETs) has received important consideration to assist the inter-vehicle communication for overcoming the vehicle to vehicle frequent disconnection problem. During rush hour, an RSU may be overloaded by many requests submitted by the vehicles. Due to strict realtime and short wireless transmission range coverage constraints, a heavily overloaded RSU may experience high deadline miss rate in effect of serving too many requests beyond its capacity. In this work, we investigate the vehicle submitted requests are generally two types: delay sensitive and delay tolerant. We propose a multiple-RSU model, which offers the opportunity to the RSUs suffering from handling high volume workload to transfer some of its delay tolerant requests to other RSUs, which have light workload and located in the direction in which the vehicle is heading. By a series of simulation experiments, we also support our multiple-RSU based co-operative load transferring model, which extensively outperforms the single independent RSU based VANETs model against a number of performance metrics. © 2011 IEEE.
