Implementation of the Wireless Autonomous Spanning Tree Protocol on Mote-Class Devices
The Wireless Autonomous Spanning Tree Protocol combines medium access control and routing to streamline energy-efficient communication in Wireless Body Area Networks. As these networks generally contain low-end resource-constrained devices, a thorough evaluation on real hardware is essential to the validation of any protocol. The authors present their implementation of the Wireless Autonomous Spanning Tree Protocol on mote-class devices, and highlight the challenges of taming the vagaries of low-power wireless that do not arise in simulation-based evaluations. They study the performance of the protocol in several dimensions, with a special emphasis on energy-efficiency. Their comprehensive set of experimental results indicates that the protocol can achieve low duty cycles if used jointly with a low-power link layer.
