Abstract:
Aspects of traffic aware slot assignment are described, for example, in a multi-hop wireless network comprising a plurality of nodes. In some aspects, an apparatus of a wireless device is configured to decode signaling, received from a node of the multi-hop network, to determine an indication of a change to a topology of the multi-hop network. The apparatus is further configured to, in response to a determination, from the decoded signaling, of an addition of a second node to the multi-hop network topology, increment a total of a number of descendant nodes, and allocate one or more transmission slots to a number of unused slots in one or more transmission opportunity regions of a slotframe, wherein the slotframe includes a repeating pattern of one or more transmission opportunity periods for a plurality of nodes in the network.
Abstract:
A technology is described for determining a position of a HBC (Human Body Channel) sensor. An example method may include receiving signal data for a radio signal from a first transmitting HBC sensor transmitted over a human body channel. A signal loss of the radio signal can be calculated using the signal data received from the first transmitting HBC sensor, where the signal loss may be a function of distance of the first transmitting HBC sensor from a receiver. A distance of the first transmitting HBC sensor from the receiver can then be determined based in part on the signal loss and a relative position of the first transmitting HBC sensor can be identified based in part on the distance between the first transmitting HBC sensor and the receiver.

Abstract:
A garment includes a passive human body communication (HBC) component that includes, for example, a storage element. The garment has conductive cuffs and a flexible conductive trace connecting the cuffs to the HBC component. When a user wearing the garment touches the electrodes of an HBC interface on an external host device, the host device powers the HBC component and may send or receive data from the HBC component. The power and the data travel over the user's body from the interface electrodes to the cuffs, and at least partially through the conductive trace from the cuffs to the HBC component.

Some demonstrative embodiments include apparatuses, devices, systems and methods of managing a wearable device ensemble. For example, a wearable device may include a memory to store a plurality of device identifiers of a plurality of wearable devices belonging to a wearable device ensemble; a human body communication (HBC) transceiver to communicate over an HBC network via a body of a user, the HBC transceiver to receive via the HBC network one or more detected identifiers of one or more detected wearable devices on the body; and an ensemble manager to manage the wearable device ensemble, and to generate an alert based on a comparison between the one or more detected identifiers and the plurality of device identifiers.
Abstract:
Techniques disclosed for accurately predicting the occurrence of anomalous sensor readings within a sensor network and advantageously using these predictions to limit the amount of power used by relay nodes within the sensor network. Some examples analyze spatial and temporal characteristics of anomalous sensor readings to predict future occurrences. In these examples, the relay nodes operate in a reduced power mode for periods of time in which anomalous sensor readings are not predicted to occur. Also, in these examples, only relay nodes in a path between a sensor predicting an anomalous reading and a gateway of the sensor network operate in full power mode. This feature allows other relay nodes to remain in the reduced power mode even when an anomalous sensor reading is predicted elsewhere in the sensor network.

Abstract:
Data can be transferred from one device to another in the Internet of Things without using a network by a touch-based human body communication (HBC) interaction between a wearable storage module and HBC-compatible interface pads on external host devices. Information on a source host device is copied to the wearable storage module when the user touches the source device's HBC interface pad, can be stored indefinitely on the wearable module, and is copied to a destination host device when the user touches the destination devices HBC interface pad. Because the interface pads only need to be simple electrodes, their size and shape can be widely varied to fit the host devices.

Abstract:
In various embodiments, two wireless communication devices may communicate with each other using multiple protocols, by dividing the data to be communicated into multiple portions, and using each protocol to communicate different portions. The different protocols may be used simultaneously or concurrently. This multi-protocol technique may be used in several different ways to provide different types of advantages in wireless communications.
