Channel Surfing to Mitigate against Jamming Attacks on Safety Applications in Vehicular Networks

Vehicular networks play a key role in Intelligent Transportation System (ITS) that makes transportation safer and more convenient. Most applications in ITS require information carried by basic safety messages (BSMs) to be exchanged periodically among vehicles. However, BSMs are vulnerable to different types of attacks, especially, jamming attack due to their limited short message length and life span. In this paper, we analyze the impact of jamming attack on BSMs and initially propose a random channel surfing scheme on attempting to react to the attack. The scheme is investigated by extendible mathematical model and simulation in NS-3. Obtained results provide a reference to design an optimal channel surfing scheme that adapts to its supported applications.
