  • Publication number: 20200359296
    Abstract: The proposal concerns a method of adaptive route selection in a node of a wireless mesh communication network. Such method is based on the Reinforcement Learning-based adaptive routing scheme. The proposal includes the idea of estimating initial reward values for the path discovery phase in dependence of the signal strength of the received signal and the number of hops the received route request message (RREQ) or route reply message (RREP) experienced during traversing in the network. Further improvements concern the idea of a feedback reward calculation for the routing absent the path discovery process as well as an improved method of route selection based on calculation of a temperature parameter for a Gibbs-Boltzmann distribution, which allows a dynamic adjustment of the node selection probabilities. Another improvement concerns a part of the reward function calculation, related to an exponential fallback mechanism on packet loss events.

    Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.

    Abstract: In one embodiment, a supervisory service for a wireless network computes a compressive sensing schedule for a plurality of sensors in the wireless network. The service sends target wake time (TWT) messages to a subset of the plurality of sensors according to the computed compressive sensing schedule. The service receives, in response to the TWT messages, sensor readings from the subset of the plurality of sensors. The service performs compressive sensing on the received sensor readings.

    Abstract: Techniques for power saving by remote wireless mobile devices are provided, in particular by stations (STAs) during downlink (DL) multiple-user multiple-input and multiple-output (MU-MIMO) transmissions in an Institute of Electrical and Electronics Engineers (IEEE) 802.11ay network when reverse direction (RD) transmissions are either enabled and not enabled. Various embodiments enable each STA in a group of STAs to determine an order in which the STAs are requested to send a block acknowledgement (BACK) and which STAs will be granted an RD transmission. Further, a duration of each RD transmission is provided to each STA. Based on the provided information, each STA can determine times to enter a power saving mode. Other embodiments are described and claimed.

    Abstract: Embodiments of the present disclosure relate to handling wake up signaling in discontinuous reception. A method comprises determining, at an apparatus, whether an active time during which the apparatus monitors transmissions from a further apparatus overlaps with at least one occasion for monitoring wake up signaling. The method further comprises in response to the active time overlapping with the at least one occasion, skipping monitoring wake up signaling on the at least one occasion. As such, power consumption for monitoring wake up signaling during the active time can be reduced.

    Abstract: A cellular modem is configured for low power applications. In some instances, the cellular modem includes a transceiver, a processor to control the transceiver, a memory device in communication with the processor, and a general-purpose input/output (GPIO) pin, controlled by the processor. In an example, the cellular modem receives an appointed time for an upcoming communication and determines a time to activate a power supply. The determination may be based at least in part on the appointed time for the communication, so that the power supply is ready to supply power at a level consistent with use of the transceiver at the appointed time of the communication. At the determined time, a signal from the GPIO pin is used to activate the power supply, resulting in an increase in power supplied to the cellular modem in a just-in-time manner.

    Abstract: In one embodiment, a device in a network receives, at its wireless receiver, a preamble of a spatially modulated packet. The device analyzes the preamble of the packet to identify a transmit antenna index of the packet. The device determines that the packet was not destined for the device, based on the transmit antenna index of the packet. The device depowers, prior to decoding the complete packet, the wireless receiver of the device, based on the determination that the packet was not destined for the device.
