Vehicular ad hoc networks(VANETs)aim to get the intelligent communication for vehicular networks,they can extraordinarily improve the security and efficiency issues of road traffic.Data dissemination is the base of communication,it acts as an important role in VANETs system.In this paper,we survey main results of data dissemination in vehicle to vehicle(V2V)communications,and expound this review on three parts:routing protocols,mobility model and security,all of which deeply affect the transmission performance in VANETs.We present the main representative research techniques and achievements in each category,and at last,further conclude the research trends and challenges for data dissemination in VANETs.
Vehicular ad hoc networks （VANETs） aim to get the intelligent communication for vehicular networks, they can extraordinarily improve the security and effi- ciency issues of road traffic. Data dissemination is the base of communication, it acts as an important role in VANETs system. In this paper, we survey main results of data dis- semination in vehicle to vehicle （V2V） communications, and expound this review on three parts： routing protocols, mobility model and security, all of which deeply affect the transmission performance in VANETs. We present the main representative research techniques and achievements in each category, and at last, further conclude the research trends and challenges for data dissemination in VANETs.
