摘要：In the past few decades, the number of vehicles on road has been rapidly increasing. Due to this high density of vehicles, road accidents and the potential threats on road are also increasing. To reduce these factors, VANET technology which uses moving car as nodes in a network to create a mobile network is adapted to enhance the vehicular technology by disseminating messages to each other. Since vehicles have high mobility, warning messages have to be quickly disseminated in order to reach maximum number of vehicles on road. The notification to the nearby vehicle is simply done by broadcasting the messages, which is retransmitted over and again by the vehicles simultaneously to other nearby vehicles. Selection of a set of forwarding nodes is a challenging task. In this work, a Cell Structured Broadcast Modeling Algorithm (CSBMA) is proposed to design a virtual hexagon network to remove the broadcast storm problem in real urban scenarios. The proposed work is a sender-initiated broadcast approach in which a sender estimates its neighbor location with a non-geometric broadcast approach and selects a set of forwarding candidate nodes located at the boundary of sender�s nodes based on communication area overlap values. A simple random backoff mechanism is also proposed to reduce the packet collisions.
