“…In [4], the authors extend the adjustable analog component and include an RF mixer. To address the challenge on the digital side, adjustable digital components are proposed in [10], [11], and [6]. The authors exploit diverse reconfiguration techniques such as under-sampling and approximate computing to enable configurable noise-robustness vs. power-consumption knobs.…”

“…To achieve adjustability to channel variations, different signal-quality vs. energy trade-off configurations can be provided in hardware to match the required signal quality to the transmission and reception efforts. Run-time adaptation has been demonstrated in a variety of receiver components such as the Low Noise Amplifier (LNA) [3], the LNA and Mixer combination [4], the Analog-to-Digital Converter (ADC) [5], and the digital baseband [6]. Recent work demonstrates how to configure an adjustable receiver at network level [7].…”

“…While TPC reduces the power of transmission, RSC reduces the power of reception with a similar impact on the communication range. The implementation of an analog front end and a digital baseband enabling RSC are described in [8] and [9], respectively. These papers show receiver implementations with adjustable circuit-level parameters that provide a sensitivity-power trade-off required for RSC.…”

“…R sens also depends on the signal processing in the DBB. The first component of R sens , ( S N ) min , can be traded for power savings in the DBB using adequate computing as shown in [9]. The digital filters can be designed in several by-passable stages, which can be shut down and/or clock gated for power savings.…”

“…Low data rates and FSK- and PSK-based modulations are commonly used, while some use sub-GHz bands as well in search of less interference and more signal integrity. Especially noteworthy are the IEEE 802.15.4-based protocols with spread spectrum (DSSS) [ 30 ] and LoRaWAN implementing it dynamically with its proprietary algorithm.…”

Although the number of Internet of Things devices increases every year, efforts to decrease hardware energy demands and to improve efficiencies of the energy-harvesting stages have reached an ultra-low power level. However, no current standard of wireless communication protocol (WCP) can fully address those scenarios. Our focus in this paper is to introduce treNch, a novel WCP implementing the cross-layer principle to use the power input for adapting its operation in a dynamic manner that goes from pure best-effort to nearly real time. Together with the energy-management algorithm, it operates with asynchronous transmissions, synchronous and optional receptions, short frame sizes and a light architecture that gives control to the nodes. These features make treNch an optimal option for wireless sensor networks with ultra-low power demands and severe energy fluctuations. We demonstrate through a comparison with different modes of Bluetooth Low Energy (BLE) a decrease of the power consumption in 1 to 2 orders of magnitude for different scenarios at equal quality of service. Moreover, we propose some security optimizations, such as shorter over-the-air counters, to reduce the packet overhead without decreasing the security level. Finally, we discuss other features aside of the energy needs, such as latency, reliability or topology, brought again against BLE.
