Advances in wireless vehicular networks present us with opportunities for developing new distributed traffic control algorithms that avoid phenomena such as abrupt phase transitions. Towards this end, we study the problem of distributed traffic control in a partitioned plane where the movement of all entities (vehicles) within each partition (cell) is tightly coupled. We present a distributed traffic control protocol that guarantees minimum separation between vehicles at all times, even when some cells' control software may fail. Once failures cease, the protocol is guaranteed to stabilize and the vehicles with feasible paths to a target cell make progress towards it. The algorithm relies on two general principles: temporary blocking for maintenance of safety and local geographical routing for guaranteeing progress. Our proofs use mostly assertional reasoning and may serve as a template for analyzing other safe and stabilizing distributed traffic control protocols. We also present simulation results which provide estimates of throughput as a function of vehicle velocity, safety separation, path complexity, and failure-recovery rates.
The advent of multi-core processors has made parallelcomputing techniques mandatory on main stream systems. With the recent rise of hardware accelerators, hybrid parallelism adds yet another dimension of complexity t...

in this paper, Spatial Correlation-based distributed Compressed Sensing (SCDCS) model and algorithm are presented in Wireless Sensor networks (WSN), where spatial correlation and joint sparse models between the sensor nodes can be exploited in order to compress and reconstruct sensor observations in an energy efficient manner based on coding/decoding algorithm of SCDCS. Finally, the analysis of relationship between reconstruction error and compression ratio in SCDCS is carried out in simulation. Simulation results show that SCDCS can achieve acceptable estimation accuracy in an energy efficient way.
In this paper, we propose an algorithm for parallel sorting on Recursive Dual-Net with an m-cube (Qm) as its base network. The Recursive Dual-Net RDNκ(Qm) for k > 0 has 2 2κm+2κ-1 nodes and m+ κ links per node....
