An eNodeB or other cell access point device can receive demand data from mobile devices served by the cell. The demand data can represent an estimate of demand over a future period for network resources (e.g., bandwidth). The cell can aggregate this demand data and determine price data for the time period or for various intervals of the time period, then transmit the price data to the mobile devices. The price data can operate as a collaborative approach to scheduling traffic. For example, data (e.g., delay tolerant data) can be shifted (e.g., delayed for a few seconds) based on an examination of the price data in conjunction a determined priority of the data. Such can be applicable to data traffic not traditionally thought of as delay tolerant such as streaming video or web browsing, and can be accomplished without negatively impacting the quality of service or experience of the client.

Collaborative scheduling of last hop cellular traffic

Disclosed herein are systems, methods, and computer-readable storage devices for reducing inter-cellsite interference during full-duplex communication. A system receives a channel amplitude and a phase estimate between a first station and a second station, the first station and the second station creating inter-cellsite interference on a channel during full-duplex communications. The system calculates a level of the inter-cellsite interference between the first station and the second station based on the channel amplitude and the phase estimate and generates a cancellation signal based on the inter-cellsite interference. The system then communicates the cancellation signal to the first station for transmission with additional data during additional full-duplex communications.

System and method for reducing inter-cellsite interference in full-duplex communications

A method and computer-readable storage device and apparatus for controlling a roadway resource are disclosed. For example, the method receives from a device associated with a vehicle a request to reach a target destination by a target arrival time and a maximum payment amount to reach the target destination by the target arrival time. The method next determining a route to the target destination and determines a roadway resource along the route that is controllable. The method then sends an instruction to the device associated with the vehicle, where the instruction indicates to navigate the vehicle along the route and controls the roadway resource to enable the vehicle to reach the target destination by the target arrival time.

A reconstruction may be divided into a set of partial operations and scheduled in parallel using a distributed protocol which overlays a reduction tree to aggregate the results. In addition, a scheduling algorithm called multiple partial parallel repair is introduced for handling concurrent failures. Multiple reconstructions may be coordinated in parallel while working to minimize the conflict for shared resources.

Parallel partial repair of storage

A traffic management mechanism can employ a two-tiered approach for managing background traffic based on prioritizing tasks by remaining time flexibility then scheduling prioritized tasks using linear programming.

Background traffic management

A method, a non-transitory computer-readable medium and an apparatus for receiving a data packet that is transmitted from a first sensor node are disclosed. For example, the method performs a channel scan of a particular burst of channel scans. When the preamble packet is detected, the method determines whether the preamble packet is addressed to the second sensor node. When the preamble packet is addressed to the second sensor node, the method sends an acknowledgement packet to the first sensor node. The method then receives the data packet that is transmitted from the first sensor node. The method then sleeps for a duration of time, when there is no packet transmission that is ongoing that is destined to the second sensor node.

Method and apparatus for reducing energy consumption of radio communications in a wireless sensor network

Vehicle-to-vehicle and vehicle-to-infrastructure communications are accomplished via a scalable ad hoc geographic routing protocol. As vehicles move along roadways, they can query other vehicles and entities for information. Responses to queries can be used to determine information such as traffic conditions, a retail store sale, that a restaurant has tables available, and/or that parking spaces are available, for example. Businesses, vehicles, and other entities along roadways can geocast pertinent information to vehicles passing by. Vehicles can cache information as it is received.

Vehicular communications using a scalable ad hoc geographic routing protocol

A protocol for providing location-based communication services in wireless sensor networks utilizes dynamic selection of forwarding devices, dynamic forwarding decisions, and intelligent backoff. Dynamic selection of forwarding devices limits the number of transmissions by dynamically selecting the devices that forward a message. Dynamic forwarding decisions implement different heuristics for different devices. According to intelligent backoff, devices that are closer to a destination region backoff for a shorter period of time than those which are further away from the destination region.

Geocast protocol for wireless sensor network

A protocol for optimizing the energy for code upload to sensors in a wireless sensor network and speeding up the dissemination if multiple sources of code are available. Energy optimization is achieved by equipping each node with limited non-local topology information, which it uses to determine the time when it can sleep since code is not being distributed in its vicinity. Another aspect of the invention is a protocol that facilitates secure upload of code in the wireless sensor network. The secure communication protocol divides the sensor field into control groups each with a control node, and manages data exchange between nodes within a control group through the mediation of a control head which provides the common key. The keys are refreshed periodically and the control nodes are changed periodically to enhance security. The protocol facilitates secure communication between sensor nodes despite the compromise of other nodes in the network.

Protocol for secure and energy-efficient reprogramming of wireless multi-hop sensor networks

A method for wirelessly transferring data between nodes may include periodically waking a receiving node from a sleep mode to a receive mode and returning the receiving node to the sleep mode, where, in the receive mode, the receiving node samples a plurality of wake-up channels; transmitting at least one wake-up preamble packet by a transmitting node on at least one of the plurality of wake-up channels; receiving, by the receiving node while in the receive mode, the wake-up preamble packet; transmitting, by the receiving node and responsive to receiving the wake-up preamble packet, an acknowledgement; transmitting, by the transmitting node and responsive to receiving the acknowledgement, a data frame on at least one data channel; and/or receiving, by the receiving node, the data frame. Some methods may include estimating a wake-up time of the receiving node and/or performing a clear channel assessment prior to transmitting the wake-up preamble packet.

Asynchronous low-power multi-channel media access control

A protocol for optimizing the energy for code upload to sensors in a wireless sensor network and speeding up the dissemination if multiple sources of code are available. Energy optimization is achieved by equipping each node with limited non-local topology information, which it uses to determine the time when it can go to sleep since code is not being distributed in its vicinity. Another aspect of the invention is a protocol that facilitates secure upload of code in the wireless sensor network. The secure communication protocol divides the sensor field into control groups each with a control node, and manages data exchange between nodes within a control group through the mediation of a control head which provides the common key. The keys are refreshed periodically and the control nodes are changed periodically to enhance security. The protocol facilitates secure communication between sensor nodes despite the compromise of any number of other nodes in the network.
