Abstract

Vehicular delay tolerant networks have proven to be a low-cost solution with an attempt to provide connectivity in the presence of vehicular mobility. In this paper, we propose a bivious relaying scheme to minimize the communication outage experienced by a vehicle within an uncovered area between two distant neighboring Road Side Units (RSUs). Our proposed scheme selects two relays for a target vehicle, one when it leaves the coverage area and the other when it is on the way to enter the next distant RSU. We analyze the effect of our proposed bivious relaying scheme with the existing single relay selection scheme using the interior point algorithm. Monte-Carlo technique is also used with 100,000 iterations to show the behavior of this stochastic process. The analytical results show that the bivious relaying scheme provides a better minimized communication outage time compared to the single relaying scheme.
