摘要： Quality of information (QoI) assessment in dynamic sensor networks that incudes evaluating, by a computer, a first value reflective of available reports from sensors that are dynamically associated with the computer. 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.

摘要： Methods and apparatus for managing quality of service of computing resources are presented. For example, a method implemented on a processor for managing quality of service of computing resources includes identifying, by the processor, one or more devices of a user on a network of the user; obtaining, by the processor, at least one management module for the identified one or more devices; installing the at least one management module in the processor; monitoring, by the processor, the one or more devices of the user for a problem; and determining, by the processor, a domain in which a root cause of the problem resides and, optionally, the root cause of the problem. The management module comprises information pertaining to a corresponding device. Further, the method may detect quality of service (QoS) problems and determine if the problems reside in a user domain or a service provider domain.

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 method for measuring trust in a transaction over a public key certificate network includes associating each edge KA→KB of an public key certificate network connecting two public keys KA and KB with a probability p that information about KB is reliable, and a confidence c that is a total dollar amount of transactions which have involved using edge KA→KB. One or more authentication paths are formed in the public key certificate network starting from public key KS and ending with a target public key KT. A limit l of an amount of insurance that an owner of KS is willing to provide to a user interested in a transaction with an owner of KT is calculated, and for each amount m
