Vehicular Ad Hoc/Sensor Networks in Smart Cities

Abstract

Smart city comprises numerous technologies and depends on sensors to be aware of its environment. Vehicular sensing where vehicles on the road continuously gather, process, and share location-relevant sensor data (e.g., road condition, traffic flow) is emerging as a new network paradigm for sensor information sharing in urban environments. In this chapter, we introduce the vehicular network and the challenges in it. We will briefly discuss the existing routing protocols for vehicular networks, and analyze them by a macro–micro model. In addition, we will also cover the vehicular sensor applications in smart cities.
