Wireless sensor networks are drawing much attention as an effective means to enable the Internet of Things. In this context, energy efficiency is an important requirement in applications where battery-powered sensing devices are exploited. Battery power saving can be addressed using many techniques, concerning different layers of the OSI model. This work addresses energy consumption in MAC protocols from a transceiver usage perspective. We first describe a set of protocols that includes IEEE 802.15.4 and IEEE 802.15.4e DSME.

Abstract
Wireless sensor networks are drawing much attention as an effective means to enable the Internet of Things. In this context, energy efficiency is an important requirement in applications where battery-powered sensing devices are exploited. Battery power saving can be addressed using many techniques, concerning different layers of the OSI model. This work addresses energy consumption in MAC protocols from a transceiver usage perspective. We first describe a set of protocols that includes IEEE 802.15.4 and IEEE 802.15.4e DSME. Then, we analyze their energy consumption and propose a set of Enhancements for Low-Power Instrumentation DSME Applications. Finally, given a wireless network topology, we compare the performance of the above mentioned protocols by simulations. Obtained results show that, for end devices, the proposed approach allows an energy consumption reduction up to a factor of 9 with respect to the IEEE 802.15.4, while enabling for higher throughput, and up to a factor of 7 with regard to native IEEE 802.15.4e DSME. © 2014 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
