| 20090327996 | Framework for Programming Embedded System Applications - The disclosure describes a method for programming applications for embedded systems such as sensor nodes. In an embodiment, this comprises writing embedded system applications in a high-level language such as C# or Java using a software development framework which includes a set of tools and class libraries. The class libraries contain pre-written code to carry out tasks which may be required of an embedded system. The class libraries may be extended following identification of a need for a particular function in an embedded system. Developed applications may be subsequently stored on the embedded system but executed on a gateway computing device which interacts with the embedded system. This means that the application(s) can be executed without requiring the presence of a virtual execution system located on the embedded system while allowing a high-level programming model for application programmers. | 12-31-2009 |
| 20090328078 | Execution of Embedded System Applications - A method of executing embedded system applications is disclosed. In an embodiment, an embedded system stores a software application for processing data collected by the embedded system and/or for controlling the embedded system. The embedded system transmits the application to a nearby computing device. The computing device executes the application using its own processing capability. The application contains instructions which, when executed, cause the computing device to interact with the embedded system. This may result in the computing device controlling the embedded system or in data being downloaded from the embedded system and processed by the computing device. | 12-31-2009 |
| 20100091715 | COGNITIVE CHANNEL ADAPTATION IN WIRELESS SENSOR NETWORKS - Cognitive radio adaptation is employed in WSNs to reduce effects of RF interference. Communication channel quality is assessed locally at each node. Using beacons to propagate channel quality and node related information among the nodes of the network, channel adaptation decision is made either centrally by identifying a channel that is optimum for a majority of nodes through a tree-structure dissemination (Majority Voting Scheme) or in a distributed manner by identifying a channel where maximum interference for any node is less than maximum interference on the other channels (Veto Voting Scheme). If two channels have the same level of maximal interference, the channel with a lesser number is chosen. Channel quality assessment may be optimized based on expected interference type and/or statistical methods. | 04-15-2010 |

| 20100085975 | FRAMEWORK FOR OPTIMIZING AND SIMPLIFYING NETWORK COMMUNICATION IN CLOSE PROXIMITY NETWORKS - A framework capable of providing transparent handling of network traffic in close proximity networks such as home networks is provided. A single virtual network interface is exposed to users/applications on connected devices. A virtual network interface manager determines available physical network interfaces and switches to a different physical network interface or a different configuration on the same physical network interface in a transparent manner to the communicating application(s). This enables the framework to optimize network communications for the communicating applications, devices, and users based on predefined criteria, application requirements such as different data throughput, or changing environment conditions such as interference. Network communication operations are also simplified for users since they are no longer required to have the necessary knowledge for configuring physical network interfaces manually in response to changing conditions. | 04-08-2010 |

| 20090196173 | Management of a Wireless Network - The disclosure describes a system for active channel management in a wireless network. The system may include spectrum monitoring in order to determine channel usage within a wireless network and/or to provide a projected transmission quality for each available channel. Another aspect of the system concerns allowing nodes in a wireless network to exchange spectrum usage data. The system may include renegotiation and handover of data transmission between channels and/or different wireless technologies. | 08-06-2009 |
| 20090296718 | Device Virtualization - Methods and apparatus for device virtualization and for communication between network devices are described. In one example, all devices on a first Local Area Network (LAN | 12-03-2009 |
| 20100017602 | Ad-Hoc Trust Establishment Using Visual Verification - Methods for ad-hoc trust establishment using visual verification are described. In a first embodiment, a visual representation of a shared data is generated on two or more devices and the visual representations generated can be visually compared by a user. This method can be used to verify that the correct devices are involved in a negotiation, when pre-existing trust relationships do not exist between the devices. The visual representation may, for example, comprise a picture with a number of different elements, each representing a part of the shared data. In another embodiment, a method of secure key exchange is described in which, before sharing the keys, the parties exchange information which encapsulates the key. This information can be used subsequently to check that a party has not changed the key that they are using and prevents a man in the middle attack. | 01-21-2010 |
