Today, modern traffic control systems are necessary to obtain maximum efficiency from the highway system. For the traffic controller to respond to the needs of traffic, it must be able to sense traffic conditions at all times with reasonable accuracy. This vehicledetection requirement has resulted in extensive research and development of vehicular-detection systems. Because of its performance r...

Ad hoc networks mostly operate over open environments and are hence vulnerable to a large body of threats. This calls for coupling preventive mechanisms, e.g., firewall, with advanced intrusion detection. To meet this requirement, we introduce IDAR, a signatureand log-based distributed intrusion detector dedicated to ad hoc routing protocols. Contrary to existing systems that observe packets, I...

Missing input data is a common drawback in many real-life pattern classification scenarios. The ability of missing data handling has become a fundamental requirement for pattern classification because an inappropriate treatment may cause large errors or false results on classification. The absence of certain values for relevant data attributes can seriously affect the accuracy of classification...

Deadlock detection is one of the most discussed problems in the literature. Although several algorithms have been proposed, the problem is still open. In general, the correct operation of an algorithm depends on the requirement model being considered. This article introduces a deadlockdetection algorithm for the OR model. The algorithm is complete, because it detects all deadlocks, and it is co...
