Comprehensive Review of Sleep/Wake Scheduling in Wireless Sensor Networks

Sleep/wake scheduling is an essential consideration in sensor network applications. Finding an optimal sleep/wake scheduling strategy that would minimize computation and communication overhead, be resilient to node failures, and provide high-quality data service is extremely challenging. In this paper, we present and compare several state-of-the-art algorithms and techniques that aim to address the sleep/wake scheduling issue, which are divided into distributed and centralized manners. Meanwhile, the advantages and disadvantages of these scheduling models and algorithms are discussed. together with open research issues.
