Abstract: Vehicular Sensor Network (VSN) is an emerging architecture used to sense the physical word. In VSNs the vehicular sensors are placed in moving vehicles like cars, buses etc. Because of the highly dynamic environment, frequent disconnection and patterned mobility, it is necessary and important to provide routing protocols which adapt to these environments. Since, vehicles moves fast the battery power and the processing capability will not be a constraint. This paper provides with the characteristics of the VSN environment, which should be considered while designing the routing algorithm. The Routing in Vehicular networks are broadly classified into five categories Topology based, Position based, Cluster based, Geocast and Broadcast. Based on these categories, the recent routing protocols are classified and compared with others.
