Safe and Secure Control of Swarms of Vehicles by Small-World Theory

“…The present paper considers a new paradigm for V2V [16] connectivity, based on the addition of a few random long-range connections, to take advantage of the big opportunity the emerging new technologies offer. These additional communication channels are superimposed to the car-following mechanism, considered in more conventional traffic dynamics [17][18][19][20][21][22][23]. The original contribution of this investigation can be summarized as follows: (i) it is shown how few long-range connections are highly beneficial for the safety of the traffic system, diminishing the probability of collisions, offering a higher level of traffic flow synchronization, (ii) this safety benefit can be made robust with respect to the failure of some communication channels, the system exhibiting an intrinsic security if simple connectivity paradigms are followed, (iii) the method is based on re-adapting the Small-World theory, originally introduced in social sciences [24][25][26] to a network of cooperating vehicles.…”
