Computing the bandwidth-delay-constrained least-cost multicast routing tree is an NP-complete problem. In this paper, we propose a novel QoS-based multicast routing algorithm based on the genetic algorithms (GA). In the proposed algorithm, the connectivity matrix of edges is used for genotype representation. Some novel heuristics are also proposed for(More)
Target tracking is one of the applications of wireless sensor network which is set up in the areas of field surveillance, habitat monitoring, and intruder tracking. Energy saving is one of the main challenges in target tracking sensor networks. In this paper, we present a Clustering and Prediction-Based Protocol (CPBP) for Target Tracking in Wireless Sensor(More)

Wireless sensor networks (WSN) are currently being applied to energy conservation applications such as light control. We propose a design for such a system called a lighting automatic control system (LACS). The LACS system contains a centralized or distributed architecture determined by application requirements and space usage. The system optimizes the(More)
In this paper we propose a distributed deadlock detection algorithm on the basis of history-based edge chasing which resolves the deadlock as soon as detects it without waiting for the probe to return back. This action reduces the average persistence time of the deadlock in compare with other similar algorithms in distributed systems. Our proposed algorithm(More)
