Benefits of Joint Optimization of Tunable Wake-up Radio Architecture and Protocols

With the massive deployment of IoT applications, Wake-up Radio, which represents the ultimate frontier in low power communication, has received an increased interest and has been demonstrated for several applications. However, when considering these different applications, the requirements are widely spread in terms of range, energy consumption, latency or protocols. This results in a large panel of wake-up radio hardware solutions as shown by the benchmark paper. At the same time, advanced submicron technologies such as 28nm FD-SOI technologies offer the opportunity to develop new architectures of tunable radios. In this paper, we will present our proposed wake-up radio system architecture exploiting highly tunable building blocks. Then, based on a simplified model of the wake-up, we will analyze the capability of the protocol to exploit this flexibility to improve the performance and to answer the requirements of the different applications. The benefits and the costs will be finally evaluated as a function of the different power criteria which impact the lifetime of the systems.
