Techniques for configuring and operating a multimedia aware cloud, particularly configured for mobile device computing, are described herein. In some instances, clusters of servers are organized for general computing, graphic computing and data storage. A load balancing server may be configured to: identify multimedia types currently being processed within the multimedia edge cloud; determine desired quality of service levels for each identified multimedia type; evaluate individual abilities of devices communicating with the multimedia edge cloud; and assess bandwidth of each network over which the multimedia edge cloud communicates with a mobile device. With that information, multimedia data may be adapted accordingly, to result in an acceptable quality of service level when delivered to a specific mobile device. In one example of the techniques, graphic computing server clusters may be configured to process workload using a configuration that includes elements of both parallel and serial computing.

Predictive, multi-layer caching architectures may be used to predict which elements a user is most likely to navigate to within a collection of elements associated with a predefined layout and, in response, to increase the accessibility of these elements to a client device of the user. For instance, the techniques may utilize a predictive, multi-layer caching architecture for storing these predicted elements to decrease the latency to render these images if the user navigates within the collection of elements in the predicted manner. The collection of elements may comprise images (e.g., a 3D model, a map, etc.), video files, audio files, text files, or any other type of file that is consumable on a client device.

Predictive, multi-layer caching architectures

A depth construction module is described that receives depth images provided by two or more depth capture units. Each depth capture unit generates its depth image using a structured light technique, that is, by projecting a pattern onto an object and receiving a captured image in response thereto. The depth construction module then identifies at least one deficient portion in at least one depth image that has been received, which may be attributed to overlapping projected patterns that impinge the object. The depth construction module then uses a multi-view reconstruction technique, such as a plane sweeping technique, to supply depth information for the deficient portion. In another mode, a multi-view reconstruction technique can be used to produce an entire depth scene based on captured images received from the depth capture units, that is, without first identifying deficient portions in the depth images.

This document describes techniques for creating three-dimensional models of image collections using a network-accessible (e.g., cloud-based) computation service, rather than a client computing device. In some instances described below, the computation service performs at least a portion of the operations for creating these models in parallel.

An application programming interface and related system is presented for a middleware communication space that provides asynchronous message delivery service for partially connected mobile ad hoc networks. Embodiments of the present invention use mobile devices to bridge separated islands of networks and store and propagate messages. The system and software architecture supports methods for messaging caching, transferring and routing. More specifically, embodiments provide methods and systems that extend a communication space concept into a distributed environment and combine it with the standard Web Services technologies, i.e, SOAP, and WS series protocols. The communication space provides an extension of Web Services to mobile ad hoc networks and provides asynchronous message caching, transferring and routing.

A middle layer network protocol enhancement, virtual connectivity (VC) makes the network attachment point changes of local and remote peers transparent to applications that use network services. A virtual connectivity module local to each peer translates communication connection parameters from apparent to real and vice versa, as well as sending and receiving secure connection updates directly to and from peers. Unlike Mobile IP, no routing infrastructure modifications are required. A subscribe-notify service provides connection update notifications when direct peer-to-peer connection updates are not possible, for example, when two communicating peers move simultaneously or when the moving peer is communicating with a peer behind network address translation (NAT). Methods for detecting these conditions are disclosed, as is a virtual connectivity protocol and virtual connectivity module architecture.

A power management technique for a network including a plurality of computing devices. The power management technique includes identifying an order in which one or more devices of the plurality of computing devices can transmit data within the prescribed time period. In one aspect, the number of wakeups are reduced for the computing devices within the network by increasing a number of adjacent channel time allocation periods within a prescribed time period that share a common computing device. In one aspect, the network can be based on Time Division Multiple Access (TDMA).

A peer-to-peer (P2P) probing/network quality of service (QoS) analysis system utilizes a UDP-based probing tool for determining latency, bandwidth, and packet loss ratio between peers in a network. The probing tool enables network QoS probing between peers that connect through a network address translator. The list of peers to probe is provided by a connection server based on prior probe results and an estimate of the network condition. The list includes those peers which are predicted to have the best QoS with the requesting peer. Once the list is obtained, the requesting peer probes the actual QoS to each peer on the list, and returns these results to the connection server. P2P probing in parallel using a modified packet-pair scheme is utilized. If anomalous results are obtained, a hop-by-hop probing scheme is utilized to determine the QoS of each link. In such a scheme, differential destination measurement is utilized.

A template that specifies which parts of the structure are fixed and which parts are variable may be provided to both the device that is transmitting the mark-up language document and the device that is receiving the mark-up language document.

Orthogonal pulse polarity modulation involves wireless communication in which the polarity of modulating pulses are set responsive to positive and negative character values of a corresponding code sequence. In a described implementation, data is converted to chip waveforms, spectrum lines are removed, and pulses are appropriately shaped. For example, a data bit stream may be converted into chip waveforms using a bit stream-to-symbol segmenter, a symbol-to-code sequence mapper, and a code sequence-to-chip waveform transformer. The polarities of respective individual chips in a given chip waveform match the signs of respective individual characters in a corresponding code sequence.

A method provides differentiated quality of service (QoS) by providing adaptive updates to media access control (MAC) layer parameters on a distributed basis. The method includes calculating a failure probability for a transmission over the network, determining a target value for determining a contention window according to a mapped function of the failure probability, and altering the contention window according to a scaling function of the target value. The mapped function and the scaling can provide QoS differentiation. A wireless device ensures fairness in a wireless time slotted network and includes a network interface card (NIC), a network driver interface, a network monitor, a statistics engine, and an adaptive parameter engine for determining a target value for determining a contention window according to a mapped function of the one or more probabilities to enable an alteration of the contention window and provide new parameters for the MAC layer.
