Abstract
Abstract Vehicular Ad Hoc NETworks (VANETs) is a form of Mobile Ad hoc NETworks (MANETs) which provides a distinguished approach for Intelligent Transport System (ITS). The most challenging task in VANETs is the routing of data. This is due to the high mobility of the vehicles which induces a rapid change in the network topology. Research in the area of VANETs routing protocols have shown that position-based routing is well adapted for highly dynamic environments such as inter-vehicle communication on highway environments. However, position-based routing finds difficulties to deal with two-dimensional scenarios with obstacles (building, tree, etc), which blocked radio transmissions, and voids as it is the case for city environments. Thus, in this paper we propose a position-based routing approach for Vehicular Ad hoc NETworks which attempts to deal with obstacles and voids found in a city environment.
