Influence of radio communications on multiple intersection control by a wireless sensor network

Abstract

In this paper, we describe and enhance TAPIOCA (distribuTed and AdaPtive IntersectiOns Control Algorithm), a distributed algorithm that relies on a wireless sensor network to manage urban road traffic efficiently. We detail TAPIOCA with a special emphasis on communications and we study its reaction to losses and delays induced by the use of wireless communication. We then propose a prediction mechanism that alleviates these issues and show, using co-simulation between SUMO and OMNeT++, that such interpolation mechanisms are effectively able to replace missing or outdated data.
