Performance analysis of slotted ALOHA with periodic server vacations for energy-efficient medium access

Slotted ALOHA is one of the earliest proposed contention-based medium access solutions for wireless networks and it remains a common approach in literature. In this paper, we present the throughput and delay performance analysis for a slotted ALOHA system with periodic server vacations. By this, we mean that the service is governed by a fixed cycle composed of alternating active and inactive periods, representative of an energy-efficient medium access solution that implements sleep cycles. To our knowledge, ours is the first work to fully develop this analysis.
