摘要： A system and method are provided that use mobile collectors (303 A ,303 B ) for accessing a wireless sensor network. In certain embodiments, one or more mobile collectors having mobility that is unpredictable to a wireless sensor network are deployed for use in accessing the wireless sensor network. Thus, rather than relying on an access technique having certainty designed therein with regard to the access of a wireless sensor network, certain embodiments utilize an access technique that relies on statistical probability for accessing the wireless sensor network. For instance, by deploying a plurality of mobile collectors that are operable for accessing a wireless sensor network, a statistical probability exists that at some point (or at various points in time) at least one of the mobile collectors will travel within range of the wireless sensor network to enable access thereof.
In an embodiment, cellular phones are used for implementing a collector node. Alternatively, PDA's, laptop computers, pagers or wireless devices in cars or aircrafts can be used therefor. A sensor of the wireless sensor network can for instance be controlled and/or report humidity, light, presence of objects or movement together with timestamp and location information via an ad-hoc short range wireless network, or a infrared, ultrasonic, microwave, RFID or cellular link.

摘要： A distributed system with mechanisms for automatic selection of master and slave clocks to be used for clock synchronization. The distributed system includes a set of nodes (20-24), including a first node and a second node, each having a local clock (30-34) and a set of information (40-44) pertaining to the local clock (30-34). The first node transfers a packet (50) on a communication link (12) that carries the information (52). The second node receives the packet (50) on the communication link (12) and determines whether the local clock of the second node is a master clock that synchronizes a time value in the local clock of the first node or a slave clock that synchronizes to a time value from the local clock in the first node by comparing the information (52)in the packet (50)to the information pertaining to the local clock in the second node. Automatic selection of master and slave clocks in boundary nodes (92) is provided along with mechanisms for determining clock synchronization delays and mechanisms for reporting jitter associated with communication devices (14).

摘要： A system with methods and apparatus for authenticating measurements that resist human errors and attempts to render or present fraudulent measurements. A system obtains a measurement 22,82 and substantially contemporaneously determines a set of one or more space/time parameters for the measurement 22,82. The system includes methods and apparatus for generating a certificate in response to the measurement 22,82 and the space/time parameters such that the certificate enables a determination of whether a set of alleged data is the measurement 22, 82. obtained according to the space/time parameters.

摘要： Techniques for network based triggering in an instrument system that enable instruments to effectively signal events without hardwired trigger lines. An instrument system 100 according to the present teachings includes a first instrument and a second instrument coupled to a local area network. The first instrument is capable of performing an action in response to an event that is signaled by the second instrument. The second instrument signals the event to the first instrument by transferring a trigger message 60 via the local area network.

摘要： A method for time synchronization that avoids time synchronization inaccuracies caused by asymmetric delays internal to a device 300. Time synchronization according to the present teachings includes determining an asymmetry between an internal delay of an inbound timing packet 40 in a device 300 and an internal delay of an outbound timing packet 42 in the device 300 and correcting a time synchronization in response to the asymmetry.
