Abstract: An ad-hoc wireless network is implemented by a plurality of wireless access points to detect and report failure of a concurrently implemented conventional network. The wireless access points collect and store network status information of the conventional network and send the network status information to a centralized emergency manager when failure of the conventional network is detected. The ad-hoc wireless network may also provide backhaul connectivity to a wireless access point of the failed conventional network for emergency communication.

Abstract: A method is provided for initiating a handover of a wireless device from a first node to a second node in a communication network. The method includes steps of (a) obtaining, at a first time, a (i) speed, (ii) direction, and (iii) first location of the wireless device, (b) determining, relative to the first location, a first signal strength of the second node and a second, higher signal strength of a third node different from the second node, (c) estimating, based on the obtained (i) first location, (ii) speed, and (iii) direction, a second location for the wireless device at a second, subsequent time, (d) confirming that the second location is within a transmission range of the second node, and (e) preempting the handover to the third node by performing, prior to the second time, the handover directly from the first node to the second node.

Abstract: The present disclosure generally relates to systems, methods and software for determining an optimal burst transmission time through a modem, such as a cable modem, a wireless access point, a node in a cable network, or a satellite communication link. Particularly, the present disclosure makes it possible for a burst of queued data, defined as data above a certain percentile of a monitored traffic rate, to be transmitted by the modem at a time that provides the best chance of avoiding a collision with a co-occurring burst of data from another user connected to the same modem. In an embodiment, the systems, methods and software disclosed herein use the optimal transmission time to replace a contention window transmission time, at least for bursty data, or they completely eliminate the need for contention windows, at least for bursty data.

Abstract: A system and method for data collection and aggregation using a distributed network of communications enabled sensors connected to another primary network to achieve a secondary out-of-band monitoring perspective, for example, in power grids. The data collection system includes an aggregation and processing server configured to collect data from a variety of sensors adjacent to the monitored network each sensor includes secondary power such that it can continue data transmission even during power grid outages. The data collection system includes a method for secure real-time data ingest, machine learning enabled analysis, risk assessment, and anomaly detection on a broad geographic scale irrespective of isolated network boundaries.

Abstract: A method for predicting network-traffic bursts includes identifying, in data received by a networking device, a plurality of network-traffic bursts, each of the plurality of network-traffic bursts occurring at a respective one of plurality of burst-times {tN, tN-1, . . . , t0}. The method includes determining a time-interval τn of a next burst occurring at τn after burst-time t1 by determining respective values of τn, a parameter ξ, and a parameter η, that minimize, to within a tolerance, a quantity (fk (ξ, η, k)−(τn−tk)) for at least three values of a integer k. Parameters ξ and η are, respectively, a real and imaginary part of a power-law exponent of a power law relating predicted time-interval τn to any of the plurality of burst-times. The method includes determining, from a cumulative distribution function of a normal distribution of previously-identified network-traffic bursts, a time-duration during which the networking device may reallocate bandwidth.

Abstract: A method performed by a node of a quantum key distribution (QKD) network includes receiving, from a hub of the QKD network, a user-node pulse train of optical-pulse pairs, each of the optical-pulse pairs comprising a first pulse and a second pulse having an optical phase shift relative to the first pulse. The method further includes splitting the user-node pulse train into first and second pulse trains, calibrating an asymmetric Mach-Zehnder interferometer with the first pulse train, blocking the second pulse of each of the optical-pulse pairs of the second pulse train to generate a filtered pulse train, splitting the filtered pulse train into a timing pulse train and a pre-qubit pulse train, delaying the pre-qubit pulse train into a delayed pulse train, and encoding the delayed pulse train into a photonic-qubit pulse train and transmitting the photonic-qubit pulse train to the hub.
