This paper presents an Enhanced Slotted 1-Persistence protocol that efficiently deals with broadcast a message in dense vehicular networks. The goal of this study is to develop a protocol which improves the delivery ratio of warning messages with low end-to-end delay in high density networks while using the network bandwidth efficiently. In order to deal with data dissemination under various network...
Speeding cars and motorcycles constantly varying their speed, changing lanes or committing other apparent traffic violations as well as police cars and ambulances responding to incidents, are examples of vehicles that demonstrate hazardous traffic patterns. We propose a detection and a broadcasting protocol that run on top of vehicular ad-hoc networks and effectively alert drivers about such hazardous...
In this paper, we propose a tree-based adaptive broadcasting (TAB) algorithm for data dissemination to improve data access efficiency in vehicle communications. The proposed TAB algorithm first constructs a broadcast tree to determine the broadcast frequency of each data, and splits the broadcast tree into some broadcast wood to generate the broadcast program. In addition, this paper develops an analytical...
