Forward Decision Model For Routing In Urban Environment Of VANETS Using Improved Firefly Optimization Algorithm

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 to
