Improving Energy Autonomy in Bluetooth Smart Devices and Applications

Dear Colleagues,

Since the introduction of Bluetooth 4.0 in 2010, millions of devices that support that standard have been shipped. This unprecedented deployment of wireless technology in such a short time has to do (in part) with its integration in popular consumer devices, such as smartphones, tablets, personal computers, smart watches, sensors, fitness devices, beacons, etc. Some of these devices will serve as “natural” user interfaces and gateways for many applications, making Bluetooth Smart a strong Wireless Personal Area Network candidate for the Internet of Things (IoT). Bluetooth Smart (also known as BLE) and Bluetooth Smart Ready have been designed to work with little energy. However, improvement both at component, concept and application levels is required to enable a consumer friendly deployment of billions of devices. This can be well understood in the light of the foreseen staggering predictions for IoT devices. Bluetooth Smart enabled peripherals mostly rely on batteries as their energy source. Maintenance issues (finding those devices and exchanging batteries) are therefore poised to become a major problem as the number of installed peripherals grows, unless ways are found to extend battery life or even to do without them (using energy harvesting).

This Special Issue will focus on ways of improving the energy autonomy of Bluetooth Smart applications. That includes (but is not limited to) concepts, systems, devices, firmware, algorithms, etc. Contributions that deal with such issues (either within an application or without) are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Low Power Electronics and Applications is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
