In wireless sensor networks, some sensor nodes can switch to a sleep state to conserve energy if their neighbors can provide similar sensing coverage. In reality, when more sensor nodes sleep, a sensor network's coverage may degrade. In this paper, we evaluate the coverage-aware sleep scheduling algorithm in areas with uneven event distributions and study its performance on event detection rate and...
In this work, an extensively comparative study is conducted to demonstrate the performance of Particle Swarm Optimization (PSO) variants based on five well-known benchmark functions in the area. According to the PSO's cognitive and social factors' contribution, we categorize the PSO algorithm into five variants. Different from other research work, which included only four PSO models, we propose an...
