Nazrul Islam, Sajjad Waheed, Abul Hasnat Anik, Sudarsan Pal . A Study of Improved Security in VANET by using a Digital Signature and Hash Chain. International Journal of Computer Applications. 108, 20 ( December 2014), 20-23. DOI=10.5120/19145-0343
Day by day the total number of vehicles around the world is increasing enormously. It needs to control the vehicles for road safety. The vast development of technologies, especially the wireless technologies provide a new type of networks, such as Vehicular Ad Hoc Networks (VANETs) which provides communication between vehicle to vehicle, vehicles to server. A numerous number of new approaches are proposed such as smart cities, Intelligent Traffic System (ITS), Intelligent Light System (ILS) etc. It is difficult to control the urban traffic system by manual method. In this paper proposes an inter vehicular routing protocol using digital signature and hash chain. The inter vehicular communication using digital signature and hash function reduces this delay. Through its extensive simulation the traffic of a city environment may be controlled. The result shows that the data passing rate of inter vehicular communication decreases. As a result, each vehicle can communicate to others more quickly, which improve the road safety as well.
