Abstract:

Abstract {&}amp;ndash; This paper proposes a new and energy efficient time reservation MAC protocol for wireless sensor network, especially suitable for ultra-low duty cycle ( 0.1%) applications. For our time reservation MAC protocol, two novel components are of importance: adaptive synchronization and the time reservation mechanism. Adaptive synchronization provides reliable synchronization for duty cycles around 0.1%. It provides substantial energy savings for our MAC protocol during low data traffic scenarios. Building upon it, the time reservation mechanism enables high data throughput near the channel{&}amp;rsquo;s capacity and provides the ability for our MAC protocol to be traffic adaptive.{&}amp;nbsp; Our experimental results verify that our protocol is able to reliably maintain synchronization for a duty cycle rate of 1:1200. The traffic adaptation capability of our time reservation MAC is evaluated against S-MAC. Simulation results show our protocol to be much more energy-efficient and traffic adaptive than S-MAC, and to provide a higher throughput capacity than common active-period MAC protocols. {&}amp;nbsp; Keywords {&}amp;ndash; MAC, Ultra Low Duty Cycle, Traffic Adaptive, Sensor Network.
