“…Experiments with motes reported in [66] and results of simulations reported in [60], show that more than half of the nodes have more than one active schedule. The GSA (Global Schedule Algorithm) [66] focuses on minimizing the number of active schedules by making all nodes within a sensor network converge to a common global schedule.…”

Abstract-The wireless medium being inherently broadcast in nature and hence prone to interferences requires highly optimized medium access control (MAC) protocols. This holds particularly true for wireless sensor networks (WSNs) consisting of a large amount of miniaturized battery-powered wireless networked sensors required to operate for years with no human intervention. There has hence been a growing interest on understanding and optimizing WSN MAC protocols in recent years, where the limited and constrained resources have driven research towards primarily reducing energy consumption of MAC functionalities.In this paper, we provide a comprehensive state-of-the-art study in which we thoroughly expose the prime focus of WSN MAC protocols, design guidelines that inspired these protocols, as well as drawbacks and shortcomings of the existing solutions and how existing and emerging technology will influence future solutions.In contrast to previous surveys that focused on classifying MAC protocols according to the technique being used, we provide a thematic taxonomy in which protocols are classified according to the problems dealt with. We also show that a key element in selecting a suitable solution for a particular situation is mainly driven by the statistical properties of the generated traffic.

“…The destination address allows a node to filter out unicast packets destined to other nodes and the digest field allows it to filter out redundant broadcast. The authors in [60] show that the digest field may be a hash of the data payload or a unique sequence number.…”
