VANET Parameters and Applications: A Review

Vehicular Ad-hoc Network (VANET) represents a challenging class of mobile ad-hoc networks that enables vehicles to intelligently communicate with each other and with roadside infrastructure. VANET poses number of challenges in terms of Quality of Service (QoS) and its performance. Quality of Service depends on numerous parameters such as bandwidth, packet delivery ratio, data latency, delay variance etc. In this paper we have discussed various issues associated with data latency, efficient bandwidth utilization and packet delivery ratio in VANETs. Moreover, challenges in providing security, reliability and confidentiality of the disseminated data are elaborated. Finally, various applications of VANETs in current computing scenario are also presented.
