The subject specification comprises enhanced communication infrastructure for a multi-tier hierarchical smart distribution grid (SDG). The SDG comprises a specified number of distribution network node controller (DNNC) components employed to desirably control communications and power distribution between respective tiers of the SDG to facilitate efficient power distribution. When communication between the a DNNC in one tier and another DNNC in another tier, is desired, the DNNC can identify available communication channels and respective communication conditions of the available communication channels, and can dynamically select a subset of available data and preferred communication channel, based at least in part on predefined control criteria, to control data transmission loads in the network and facilitate real time control of the SDG. Data can be communicated via the selected communication channel. Respective DNNCs can desirably control power distribution for respective tiers, minimizing upper tier involvement in lower tier power distribution.

Methods and apparatus, including computer program products, are provided for sensing and/or transmission coverage adaptation using interference information. In one aspect there is provided a method. The method may include determining, at a node, a degree of interference at the node; receiving, at the node, at least one message from at least one neighboring node, the at least one message including another degree of interference observed at the at least one neighboring node; and adjusting, by the node based on the degree of interference at the node and the at least another degree of interference, at least one of a receiver sensitivity of the node, a clear channel assessment detection range of the node, or a transmit power of the node. Related apparatus, systems, methods, and articles are also described.

Sensing and/or transmission coverage adaptation using interference information

A method and apparatus may be configured to determine a plurality of rings. The plurality of rings surround a radar, and the plurality of rings encompass a plurality of networks surrounding the radar. The method also includes determining transmission powers corresponding to the plurality of rings. Each ring is associated with a determined transmission power. The method also includes instructing each network of the plurality of networks to perform transmissions in accordance with the determined transmission powers. Each network is instructed to use the determined transmission power that corresponds to the ring which encompasses that network.

Embodiments of systems and methods for efficient broadcasting via random linear packet combining are described. A plurality of data packets are received from a data source according to embodiments. The plurality of data packets is divided into a plurality of data blocks, and bits associated with the plurality of data blocks are multiplied by a set of coefficients to generate a plurality of product values. An encoded data packet having a plurality of encoded data blocks may also be generated by linearly combining the plurality of product values for respective data blocks of each of the plurality of data packets into corresponding encoded data blocks of the encoded data packet. Because each encoded data packet includes information about a complete set of data packets, rather than just a subset, less broadcast redundancy may be required.

Time-frequency coding in a multi-band ultra-wideband system is generally described. In this regard a hopping code agent is presented to select a frequency hopping code for encoding and decoding from a set of predetermined FHC's for communicating with other devices in a multi-band ultra-wideband (MB-UWB) network, wherein the FHC defines a sequence of two or more pulses over two or more frequencies and wherein the FHC's include a time slot that contains no transmission. Other embodiments are also disclosed and claimed.
