Abstract

Abstract : Among of the main searching field, the coverage and the connectivity of wireless sensors networks (WSNs) on the roads. The purpose of this field is tried to find a deployment model of WSNs ensuring full coverage of the roads and allowing full connectivity between sensors while using a minimum number of sensors. This deployment model allows sharing of the data collated by the WSN with the vehicular ad hoc network. The collaboration between the two networks is called hybrid sensors and vehicular networks. This hybrid network has been created to improve the road safety. The first key of success of this network is the creation of a deployment model of sensors on roads. Authors' article aims to create this deployment model. To make authors' deployment model closer as much as possible to the real environment, the authors have proposed a set of models and algorithms allowing assignment the sensors on the roads. These sensors have not similar sensing ranges, and their deployment has been made on roads having different geometric models. The results obtained prove the reliability of authors' deployment model.
