In Wireless Sensor Network (WSN), for critical event only less number of packets is transmitted. But for critical event more number of packets wants to be transmitting. So, sleep scheduling method used to increase the network lifetime. When critical event occurs, an alarm message is quickly transmitted to centre node. Then centre node broadcast the entire message to its neighbors. But in sleep scheduling, delay will be more. For sleep scheduling there will be both wakeup and sleep nodes, but the authors don't disturb any sleep nodes.
