Abstract
Vehicular ad hoc networks have many access points for communication, transmission, and collecting information of nodes and environment for organization traffic loads. In this paper, we study emergency messaging connectivity in vehicular ad hoc networks (VANETs). Intelligence transportation system applications include two types applications. Comfort applications providing information to the driver about weather, maps and directions, locations, and safety applications are crucial for safety of the driver. This includes such as emergency warning, lane-changing assistance, intersection coordination, which are provided by inter-vehicle communication. Higher No of road accidents demands an intelligent transportation system. Implanting smart sensors, communication capabilities, memory storage, and information processing units in vehicles help us to design an intelligent transportation systems. We are studying the effect of delay of emergency message dissemination. Broadcasting is the familiar way of emergency message dissemination in VANETs. To reduce the broadcasting storm problem and improve scalability of VANET networks, we use a double-head cluster-based broadcasting mechanism. In this research paper, we study the broadcasting delay emergency message of VANET network. The minimum cluster size that achieves acceptable message delivery latency is provided. The simulation results matched those of the analytical model, which showed the analytical model developed in this paper is effective and efficient.
