Abstract: Methods and systems for reliable broadcasting that use re-transmissions, in a multi-hop, time-slotted wireless network, is presented. The methods and systems evaluate the trade-off between power consumption and communication reliability, and are consequently able to provide increasing degrees of robustness for broadcasts in the wireless network. Embodiments of the present invention are able to incrementally use re-transmissions, therein trading-off battery life for an increased message completion rate or a lower packet error rate, for example, in order to reliably broadcast critical or high-priority message network-wide.

Abstract: An apparatus for joint analog and digital interference cancellation includes a receiver configured to receive an analog reference interfering signal on a reference path, and a sum of an analog interference signal and an analog signal of interest on an antenna path. An analog interference canceller may be configured to produce an analog partially interference-cancelled signal using the analog reference interfering signal and the sum of the analog interference signal and the analog signal of interest. A first analog-to-digital converter may be configured to digitize the analog reference interfering signal to produce a digital reference interfering signal. A second analog-to-digital converter may be configured to digitize the analog partially interference-cancelled signal to produce a digital partially interference-cancelled signal. A digital interference canceller may be configured to produce an interference-cancelled signal using the digital reference interfering signal and the digital partially interference-cancelled signal.

Abstract: Devices, systems, and methods for software-defined cognitive networking for wireless communications are provided. An example method of wireless communication includes performing, at a first node of a plurality of nodes, multiple network interference measurements to generate a first local interference model, receiving, from a second node of the plurality of nodes, a second local interference model, combining, at the first node, the first local interference model and the second local interference model to generate a joint interference model, generating, based on the joint interference model, a plurality of interference parameters that characterize a communication channel between the first node and the second node, selecting, based on the plurality of interference parameters, an operating waveform from a plurality of waveforms such that a performance metric for a data communication from the first node to the second node exceeds a threshold, and performing, using the operating waveform, the data communication.

Abstract: Methods, devices and systems that use a control channel to coordinate quality of data communications in software-defined heterogenous multi-hop ad hoc networks are described. In some embodiments, an example apparatus for wireless communication in a network includes performing, using a control plane, network management functions over a control channel that has a first bandwidth, implements a frequency-hopping operation, and operates at in a first frequency band, and performing, using a data plane that is physically and logically decoupled from the control plane, data forwarding functions, based on a routing decision, over at least one data channel that has a second bandwidth and operates in a second frequency band different from the first frequency band.
