Abstract: Devices, systems and methods for high-utilization low-latency multi-channel time-division multiplexing access (TDMA) are described. One example method for wireless communication includes performing, in a first time interval of a time-division multiple access (TDMA) slot, a transmission of a first data unit over a first logical channel of the plurality of logical channels, refraining from transmitting, subsequent to a completion of the transmission of the first data unit, for a second time interval immediately after the first time interval, and performing (N−1) transmissions in (N−1) time intervals for each data unit of (N−1) subsequent data units in the TDMA slot, such that a transmission of an nth data unit of the (N−1) subsequent data units is performed over an nth logical channel of the plurality of logical channels.

Abstract: Devices, systems and methods for collaborative wireless communication in a wireless network are described. One example method includes performing, by a first node of a plurality of nodes, a communication with at least a second node of the plurality of nodes, receiving, by the first node from a destination node of the plurality of nodes, a probe, computing, based on the probe, a phase of a strongest tap of a channel estimate between the first node and the destination node, computing a phase correction based on the phase of the strongest tap and a phase difference between a first phase of the first node and a second phase of a reference node, wherein the phase difference is based on the communication, and transmitting, to the destination node, a message with the phase correction.

Abstract: Methods and systems for improving communication in a multi-hop, time-slotted wireless network are presented. Embodiments of the present invention are able re-use timeslots to locally transmit information to one-hop nodes, thereby utilizing the bandwidth more efficiently. Other embodiments are able to 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. That is, these latter embodiments 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: Methods and systems for improving authenticated encryption in counter-based cipher systems are presented. Embodiments of the present invention provide secure and efficient means to achieve both the authenticity and privacy goals of authenticated encryption, and are compatible with most block cipher modes of operation, e.g. CBC, CFB and CTR, and most symmetric-key cryptographic functions, e.g. AES, DES and RC5. In particular, using block cipher encryption with data-dependent initialization vectors achieve the privacy goal and enable over-the-air transmissions to remain uncompromised, especially in scenarios that may result in the counter being reset in counter-based cipher systems.

Abstract: A method and system for maximizing throughput and minimizing latency in a communication system that supports heterogeneous links is presented. The communication system supports a primary link and an alternate link, and the method and system leverage the alternate link to reduce the overhead transmitted over the primary link, thereby increasing throughput and reducing end-to-end latency. The higher latency alternate link provides a delayed version of an information signal that corresponds to a portion of the information signal that is transmitted on the primary link. The received samples from the primary and alternate links may be used to equalize subsequent portions of the information signal received over the primary link, and may also be used for synchronization, timing recovery, DC offset removal, I/Q imbalance compensation, and frequency-offset estimation.

Abstract: Systems and methods are presented for controlling the peak-to-average-power of a baseband orthogonal-frequency-domain multiplexing (OFDM) signal by designating a subset of the available subcarriers as information-bearing data-subcarriers, and loading remaining subcarriers by symbols that are a function of the symbols loading the data-subcarriers. At the receiver, the data-dependent subcarriers are optionally combined with data-subcarriers to increase error protection.

Abstract: A method for secure key agreement among a subset of a plurality of transceivers includes generating a first ordered subset of a plurality of keys kλj, where j=0 to S. Each of the subset of the plurality of transceivers may possess at least one of the plurality of keys kλj from the first ordered subset. Each of the subset of the plurality of transceivers possessing one or more keys kλi, i=1 to S, also possesses at least one key from a second ordered subset of the plurality of keys kλj, j=0 to i−1. A key with index λ0 is designated as a group key. A binary sum of the group key kλ0 and a key kλj, where j≠0, is transmitted from one or more of the subset of the plurality of transceivers that possesses the group key kλ0.
