We analyze the performance of IEEE 802.11ah technology in an actuation use case for connected lighting from perspective latency and power consumption at actuator downlink direction. The study includes network configurations with different beacon frame transmission intervals, channel bandwidths, group stations power-save mode as well unicast-multicast transmissions using modulation coding schemes. results show existing trade off between desired station shorter intervals are required to...
Key features of the two dominating standards for unlicensed bands, IEEE 802.11 and Bluetooth Wireless Technology, are combined to obtain a physical layer (PHY) with several desirable internet things (IoT). The proposed PHY, which is referred as Narrow-band WiFi (NB-WiFi) can be supported by an OFDM transceiver available in access point (AP). In addition, NB-WiFi supports concurrent use low data rate IoT application high broadband using 802.11ax technology, based on single IFFT/FFT AP. sensor...
The use of a wake-up receiver (WUR) is an attractive means to reduce power consumption. However, when the signal (WUS) sent in-band, WUR may potentially spectrum efficiency system. In this paper, we propose multiplex WUS, based on ON-OFF keying, with user data using FDMA or OFDMA allow for efficient WURs. proposed architecture envelope detector and uncertain intermediate frequency (IF), which that will act as interference WUS. spite its low complexity, it shown by simulations good...
Power consumption is expected to be a key performance indicator for ultra-low power IoT devices. A disruptive step towards achieving years of battery life the introduction wake-up radios (WURs). The use WUR allows main radio turned off, and only woken up when packet received. commonly used modulation on-off keying (OOK) which can demodulated using simple envelope detector. In this paper we introduce partial-OOK (P-OOK), modification OOK that improve sensitivity without increasing complexity.
Backscatter communications can enable the proliferation of Zero-energy (ZE) Internet Things (IoT) services in 6G, ushering a new era green communications. To achieve widescale adoption, backscatter needs to be integrated into cellular ecosystem. This motivates need design bistatic modulation technique which is not only compatible with 3GPP New Radio (NR) physical layer but also robust direct link interference. In this paper, non-ambient system consisting carrier emitter (CE), device (BD) and...
Since the first case reported of SARS-CoV-2 end December 2019 in China, number cases quickly climbed following an exponential growth trend, demonstrating that a global pandemic is possible. As 3, 2020, total are around 65,527,000 contagions worldwide, and 1,524,000 deaths affecting 218 countries territories. In this scenario, Spain one has suffered hard way, ongoing epidemic caused by novel coronavirus SARS-CoV-2, namely COVID-19 disease. paper, we present utilization phenomenological models...
The goal of Delay Tolerant Networking (DTN) is to provide the missing ingredient for ever-growing collection communicating nodes in our solar system become a Solar System Internet (SSI). Great strides have been made modeling particular types DTNs, such as schedule- or discovery-based. Now, analogously Internet, these smaller DTNs can be considered routing domains which must stitched together form overall SSI. In this paper, we propose framework cross-domain well methodologies detecting...

With 6G on the horizon, energy harvesting backscatter paves way improved efficiency and enhanced connectivity, without conventional batteries high-power radios. Despite licensed spectrum scarcity, telecom industry explores deploying backscattering technology in bands due to higher transmitter advanced interference management [1]. Past research RF harvesters emphasized enhancing rectifier sensitivity heavily duty-cycled...

The IEEE 802.11ba Task Group is currently developing a standard for wake-up radios (WUR), intended to significantly reduce the total power consumption. In this paper, we study means multiplex signal WUR in frequency domain with data transmitted according 802.11ax standard. Due different properties of two signals, some care must be taken ensure inter-standard interference kept sufficiently low. Two approaches achieve are proposed and evaluated. first, coexistence between systems ensured by...
