The present paper investigates a new paradigm to control a swarm of moving individual vehicles, based on the introduction of a few random long-range communications in a queue dominated by short-range car-following dynamics. The theoretical approach adapts the small-world theory, originally proposed in social sciences, to the investigation of these networks. It is shown that the controlled system exhibits properties of higher synchronization and robustness with respect to communication failures. The considered application to a vehicle swarm shows how safety and security of the related traffic dynamics are strongly increased, diminishing the collision probability even in the presence of a hacker attack to some connectivity channels.

P2p System

The P2P system was build with the topological structure of the network at the application layer, network topological structure for an P2P system has a very important significance. There is currently a wide range of different topology structure of P2P network, HCPON uses two-level clustering structure, based on HCPON, we propose an efficient overlay network model based on clustering (PONM), it solves the problem that the super node only uses a single backup node as a redundant backup leading system robustness improvement is limited in unstructured P2P system. The model through a directory server to manage all nodes on the network, The results of the simulation demonstrates that,compared with HCPON, PONM has a relatively stable path stretching rate and lower average link pressure, can meet the requirements of Large-Scale P2P streaming media service needs.
