Critical Monitoring Analysis Applying Sleep / Wakeup Scheduling Algorithms for Wireless Sensor Networks

Abstract: Sleep/Wake up scheduling algorithm has been proposed for event-driven sensor networks for delay-sensitive applications where events occur rarely. The most efficient research efforts in Wireless Sensor Network are focused on energy problem since the nodes are usually battery-powered. To prolong the network lifetime, few sleep scheduling methods are always required in Wireless Sensor Networks, resulting in significant broadcasting delay, especially in large scale WSNs. In order to reduce the delay of alarm broadcasting from any sensor node in WSNs, many methods have been employed, and it is a research challenge in Wireless Sensor Networks because the Critical event monitoring has become essential through WSNs. In our research work, the performance of the different sleep/wakeup scheduling algorithms has been analyzed for minimizing the broadcast delay in WSNs and described their boon and bane of event management analysis and the issues addressed through them. Also, the Critical risk factors and the disputes of current various scheduling schemes that are employed have been briefed to maximize the utilization of Wireless sensor Networks.
