摘要： A method for continually controlling the collective behavior of a set of computing devices in a distributed data processing system. A gateway node disseminates a specification request comprising a set of parameters to a set of computing devices. The gateway node may be unaware of the number and identity of individual computing devices. Each computing node receiving the request determines whether its attributes satisfy the predicates expressed in the specification request. If so, the node processes the parameters in the specification request and modifies its own behavior based on the values in the parameters of the specification request. Subsequently, the gateway node may also observe the quality of information (QoI) values communicated from the set of computing devices. The gateway node iteratively modifies the parameters disseminated in subsequent specification requests based on a divergence between a computed quality of information value and a desired quality of information value.

摘要： A system and method for providing energy-efficient support of continuous aggregate queries in a sensor network by efficiently orchestrating the collection and transmission of data gathered by a collective set of sensors to ensure conformance to a specified QoI bound. To ensure this, the sink communicates a potentially different value of precision range or interval to each individual sensor, the sensor is adapted to only report its samples back to the sink if the sample values fall outside this specified range. An additional way to specify temporally varying precision ranges to an individual sensor or groups of sensors is provided without having to explicitly communicate the precision bounds for these different time instants. Using temporally varying precision ranges permits the exploitation of temporal correlation among the sample values recorded by an individual sensor to further reduce the need for reports from the sensors. This approach is more energy-efficient and improves performance of long-running pervasive environment monitoring applications.
摘要翻译：一种用于通过有效地协调由一组传感器收集的数据的收集和传输来确保符合指定的QoI约束来在传感器网络中提供连续聚合查询的能量效率支持的系统和方法。为了确保这一点，接收器将精确范围或间隔的潜在不同值传达给每个单独的传感器，如果采样值落在该指定范围之外，则传感器仅适用于将其样品返回到接收器。提供了一种为单个传感器或传感器组指定时间上变化的精度范围的附加方式，而不必明确地传达对于这些不同时刻的精确范围。使用时间上不同的精度范围允许利用单个传感器记录的样本值之间的时间相关性，以进一步减少对传感器报告的需要。这种方法更节能，并提高长期运行的普及环境监测应用的性能。

摘要： Provides methods and apparatus for offering tiered application services for access to network services on a pay-per-use basis in public access networks. Using personal devices, the user can access different tiers of application services on demand, without the need of any preexisting association, e.g., subscription, with the service provider of the wireless access system. Such on-demand access is obtained by providing a variety of personal identifiers, such as a credit card number or frequent flier identification. Moreover, the service offering allows a user through a personal device to modify, enhance or degrade the currently established tier of application services during the lifetime of the user's association with the access network. A network-level enforcement mechanism at access points within the access network ensures user access only to application services within the application service tier that they have paid for, and deny service accesses not within that tier.

摘要： Techniques for selecting a new compression technique or altering the currently instantiated compression technique employed over a data stream in data collection system are provided. At least one change to at least one external contextual condition is detected. One or more modifications to a defined compression technique is generated, either independently or in conjunction with one or more modifications to the event processing operators that operate on the data stream and whose output provides the values that are compressed by the defined compression technique, in response to the at least one change to the at least one external contextual condition. The defined compression technique of the at least one client device is altered in accordance with the one or more modifications to form a modified compression technique through which the unmodified or processed data stream will be compressed before being sent to the server.

摘要： Mobile wireless devices may receive data streams from multiple remote sensors. The sensors may have limited power supplies and memory capacity. Aspects of the invention use statistical characteristics of the sensor data streams and the cost of acquiring a single element of each stream to determine what sequence the sensors should send their data streams in. The cost of acquiring the data may be modified dynamically, depending on parameters such as block size. Additional factors, such as a sensor's buffer capacity, may limit the amount of stream elements that may be cached and affect the sensors' stream transmit sequence. The evaluation order may be dynamically modified using an event processing engine, to reflect both changing statistics of underlying sensor stream tuples and time-varying acquisition costs associated with individual streams. This helps to increase in the operational lifetime of the sensors and associated monitoring applications.

摘要： Techniques are disclosed for maintaining and processing provenance data in such data stream processing systems. For example, a method for processing data associated with a data stream received by a data stream processing system, wherein the system comprises a plurality of processing elements, comprising the following steps. A portion of data associated with the data stream is maintained. The maintained data comprises inputs to each processing element that contributed to an output of each processing element. In response to an alert generated by one of the processing elements, a scheduler is triggered to determine when a pre-calculation of a prospective query related to the alert should be executed. In response to the scheduler, at least a portion of the maintained data is used to determine a set of data that contributed to the alert such that the alert-contributing set of data can be used to respond to the prospective query upon arrival thereof.

摘要： Techniques are disclosed for determining and validating provenance data in such data stream processing systems. For example, a method for processing data associated with a data stream received by a data stream processing system, wherein the system comprises a plurality of processing elements, comprises the following steps. Input data elements and output data elements associated with at least one processing element of the plurality of processing elements are obtained. One or more intervals are computed for the processing element using data representing observations of associations between inputs elements and output elements of the processing element, wherein, for a given one of the intervals, one or more particular input elements contained within the given interval are determined to have contributed to a particular output element. In another method, intervals are specified, and then validated by comparing the specified intervals against intervals computed based on observations.

摘要： Techniques for managing entities identified by presence information in a communications network are provided. A condition expressing one or more predicates over one or more presence attributes in the communications network is received. A dynamic entity is generated, wherein the dynamic entity allows at least one user to subscribe thereto. The dynamic entity comprises at least one entity identified by presence information when it is determined that the at least one entity satisfies the condition. The generated dynamic entity is managed by either or both of: (i) adding to the dynamic entity at least another entity identified by presence information that satisfies the condition; and (ii) removing from the dynamic entity an entity identified by presence information that no longer satisfies the condition.
