This paper presents a distributed sleep scheduling protocol that can be used for implementing synchronous interface sleep for energy conservation in wireless Ad Hoc networks. Central ida of this protocol is to distribute a common sleep-awake cycle schedule among all nodes within a connected partition so that the nodes can turn their interface off during the sleep section of the agreed upon schedule, and they can communicate during the wake section of the schedule. By turning the interface off, the nodes can avoid idle listening consumption, which is a known reason for nonessential energy drainage in random-access network
