Abstract

Vehicular ad hoc network (VANET) is a special form of Mobile Ad hoc Network (MANET), which plays a key role in the Intelligent Transportation System (ITS). Though many outstanding geographic routing protocols are designed for VANETs, most of the existing proposals only consider a single factor, which makes the link easy to break. In this research, we propose a Routing Protocol Based on Multi-factor Decision (RMFD), which utilizes several features. The scheme is divided into two parts, namely vehicular decision management and intersection decision management. In the vehicular component, a route is established between two adjacent static nodes by calculating a fuzzy performance score using Triangular Fuzzy Number (TFN). In the Intersection management, static nodes located at the intersection are selects to decide which road segment the data will be forwarded
