The purpose of vehicular network is to serve the user with its potential applications, but this purpose is to fulfill only when networks are available to the end users. Due to open nature of wireless medium, the attackers can affect the vehicular environment. In this paper, we are providing a survey on the attackers and all possible attacks on the availability requirement of vehicular network. The main aim of this study is to describe the threat levels of all possible attacks on the availability. It has been investigated that each level has its own priorities. Threats levels and its priorities will be useful to understand the behavior of attackers and attacks in the vehicular network. © 2014 IEEE. %O cited By 11; Conference of 2014 International Conference on Computer and Information Sciences, ICCOINS 2014 ; Conference Date: 3 June 2014 Through 5 June 2014; Conference Code:112912 %J 2014 International Conference on Computer and Information Sciences, ICCOINS 2014 - A Conference of World Engineering, Science and Technology Congress, ESTCON 2014 - Proceedings %L scholars4277 %D 2014 %R 10.1109/ICCOINS.2014.6868376 %T Effects of attackers and attacks on availability requirement in vehicular network: A survey %A I.A.
