Abstract
The Internet of Things (IoT) allows the possibility for users to interact with daily life objects. At present, there is a large variety of wireless
interfaces, which makes the interoperability difficult among them and restrains the real adoption of the IoT. The present project proposes a
solution that offers a way to provide interoperability between different radio frequency technologies and, at the same time, the reduction of
energy consumption, another aspect of capital importance on the deployment of IoT. The focus of the project is on Wi-Fi, but results are
generalized for other technologies. Wi-Fi consists in a widely deployed technology, but it does not satisfy the requirements of the IoT. The
proposed project aims at improving energy performance, thus allowing the use of one single technology, the Wi-Fi technology, for all IoT
requirements, leading with different coverage ranges, bit rates and power consumptions.
The basis of the improvement in Wi-Fi performance relies on employing Wake-up Radio (WuR) solutions so that the receiver is only in the on state, and thus consuming energy, when data is being sent to it. IEEE 802.11 transmissions will be used to generate lowrate
WuR messages, that can also be extended to send identifications or even control and management messages. Traffic characteristics
for low-rate signals transmission will be analyzed in relation to standard data Wi-Fi transmissions and coexistence will be allowed. New
forthcoming IEEE 802.11ah standard (Wi-Fi HaLow), allowing low cost mode of operation, thousands of associated stations per cell, larger
coverage area, and enhanced power control mechanisms need to be studied. This WuR solution for Wi-Fi will be extended to other
wireless interfaces such as IEEE 802.15.4, 4a, 4e, Bluetooth Low Energy (BLE) or even Visible Light Communication (VLC). Moreover,
employing the same receiver and protocol for a wide range of radio frequency communication standards supposes a key aspect in order to
achieve interoperability among technologies. Thus, a Wi-Fi device will be able to talk to an IEEE 802.15.4 node through the WuR channel.
In order to transport Internet data, an adaptation layer, similar to 6LoWPAN, will be designed. Finally, taking into account the project
development, the impact of the WuR channel in the protocol architecture will be analyzed. It can be assumed that the capacity of sending
WuR frames and also information simultaneously will have impact on, at least, access protocols, node and resource discovery, routing and
congestion control. All the improvements proposed will be evaluated through theoretical analysis and simulation studies, and, where
possible, experimentally through the corresponding implementation in one of the two testbeds that will be built during the project. The use
of testbeds requires effort for installation, set-up and usage, but also allows the experimentation to be realistic and approaches the
research to the market. The review of publications and existent patents in the area allow us to conclude that we are proposing an
innovative research, thus boosting transfer to the industry. The applicant group has shown proven capacity for publication generation and
also for standards' development; this fact assures an important international impact with regard to the research that will be carried out in
the project.
