Controlling signature verification of network coded packet on VANET
There are various studies and developments to notice the traffic information to drivers in the field of Intelligent Transport System (ITS) so that they can prevent traffic accidents. Vehicles must be timely transmitted information with integrity, since it influences an action of vehicles indirectly. Digital signature provides reliability for the information. In high vehicle density area, the vehicles may receive many packets. If each vehicle verifies all signatures of received packets, the transmission delay increases. Increasing of the expired packets causes decrease of the received rate. In this paper, we propose a method for controlling the number of verification dynamically in order to decrease the transmission delay. The proposed method can suppress fall of the received rate.
