摘要： Systems and methods provide a selective instrumentation strategy for monitoring the progress of transactions in a distributed computing system. The monitoring of the transactive processing of jobs is considered through a collection of computer operating stages in a distributed system, using limited information. The monitoring is performed by observing log records (or footprints) produced during each stage of processing in the system. The footprints lack unique transaction identifiers resulting in uncertainties in monitoring transaction instances. The processing stages are selective instrumented to reduce monitoring uncertainty under the given constraints such as limited budget for instrumentation cost.

摘要： A method and system for providing on-line services to a user from a services provider over a wireless cellular network. The cellular network is located between the user and the services provider, and a distributed computer system such as the Internet is located between the services provider and the cellular network for transmitting data between the services provide and the cellular network. In one embodiment, the services provider transmits software and operating characteristics over the distributed computer system to the cellular network, and the cellular network installs this software on one or more nodes of the network. When a user connects to the cellular network for services from the service provider, the network operates the software on the one or more nodes in accordance with the operating characteristics, to provide one or more services from this one or more nodes to the user from the service provider.

摘要： A mechanism is provided for establishing a shared secret-key for secure communication between nodes in a wireless network. A first node in the wireless network provides a spreading code to a second node of the wireless network. The second node provides a first input for the key establishment to the first node using communication encoded with the spreading code. Responsive to obtaining the first input from the second node, the first node provides a second input for the key establishment to the second node using communication encoded with the spreading code. Then, the first node and the second node establish the shared secret-key using the first input and the second input.

摘要： Techniques for annotating data packets with time and/or location information in wireless networks are provided. In one aspect, a method for processing information streams produced by end-computing devices that are transmitted over a wireless network having at least one network element is provided. The method includes the following steps. Data packets which originate from the end-computing devices and are received by the network element are inspected for spatiotemporal metadata. Spatiotemporal metadata is inserted into the data packets and the data packets are transmitted if the step of inspecting the data packets reveals that the data packets are missing spatiotemporal metadata. Otherwise the data packets are transmitted if the step of inspecting the data packets reveals that spatiotemporal metadata is already present in the data packets.

A second value reflective of reports expected to have been available for evaluation about the observed phenomena is estimated. A QoI of the available reports is assessed. The assessing is based on the first value reflective of the available reports and the second value reflective of reports expected to have been available for evaluation. A third value, based on the assessing is output.
