Scheduling algorithms are one of the most important algorithms in operating systems. These algorithms have been designed for optimized use of processes from processors. One of the best algorithms for scheduling processor is Multi Layer Feedback Queue (MLFQ), algorithm which is based on use of several queues with different quanta. The most serious problem of(More)
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)
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)
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)
