Abstract
This paper explores a cluster based sleep scheduling method ton reduce the delay of alarm broadcasting from any sensor in WSNs. When a critical event occurs, an alarm message should be broadcast to the entire network. Specifically, there are two determined traffic paths for the transmission of alarm message, and level-by-level offset based wake up pattern according to the paths, respectively. When a critical event occurs, an alarm message is quickly transmitted along one of the traffic paths to center node, and then it is immediately broadcast by the center node along another path without collision. Therefore, two of the big contributions are that broadcasting delay is only 3D+2L, where D is the maximum hop of nodes to the center node, L is the length of the sleeping duty cycle, and the unit is the size of time slot.
