Abstract: A mobile backhaul inter-mesh communication point forms an interface between a wireless mesh network on a first level and a wireless mesh network on a second, higher bandwidth, level. The two wireless networks are differentiated, e.g., by causing the mesh networks to be formed using different spectra, protocols or coding, or antennae. The mobile intra-mesh communication point functions as an access point in the lower level mesh network and as a relay point in the upper level mesh network. Utilizing mobile inter-mesh communication points facilitates deployment of wireless network access points while enabling the location of access points to follow the concentration of network users. Mobile inter-mesh communication points may be deployed in personal vehicles such as cars, trucks, and motorcycles, public transportation vehicles such as busses, trains, and aircraft, emergency vehicles such as fire trucks and ambulances, and many other types of vehicles.

Abstract: Security information such as fixed or dynamically received camera location information, laser signature information, timestamp information, and network information, may be used to secure the transport and storage of surveillance video. Where the surveillance video is to be transported on a communication network, the round trip time from a video data storage server to the surveillance camera and back to the video data storage server may be monitored and periodically added to the secured video data. By checking to see whether the round trip time has changed, it may be possible to determine whether the video has been tampered with. The secured video data may also be transported over two or more paths on the network to two or more video data storage servers so that redundant copies may be stored at different primary locations. By comparing copies of the data, alteration of one of the copies may be detected.

Abstract: A system and method for preventing e-mail spoofing, in which a receiving e-mail checking server system sends a message to a confirmation server associated with a network domain of the sending system of a received e-mail message, to determine if the sender transmitted the message. The e-mail checking server sends a confirmation request e-mail, including a transmission time or unique message “key” associated with the received e-mail, to the sending domain's confirmation server. When a confirmation request is received at the confirmation server, it replies with an indication whether the message was sent at the time indicated in the confirmation request, and/or whether the message key matches that of a previously transmitted message. The confirmation server checks whether the message was in fact sent based on stored values corresponding to the send time and/or message key stored for the confirmation request message. A message may further include indication that its origin can be confirmed.

Abstract: System and method for dynamically re-directing communications sessions destined for a particular entity in a communications system, each communications session being associated with at least one predefined route. Location information indicative of a current location of the particular entity is obtained and applied to a predefined set of conditional routing rules associated with the particular entity. This rules-based processing generates a routing result, on the basis of which the at least one predefined route associated with each communications session destined for the particular entity is dynamically updated.

Abstract: A method and system for managing handover where a database that receives location information about a moving object includes information regarding which base station is used in a current radio link connection and which base stations were used from historic radio link connections. Using the base station radio link history of the object and an electronic map, a processor selects which physical path the moving object is using. Upon matching the object's path with a history of path routes on the list, the processor will apply an optimized handoff sequence to the moving object. The optimized route can be derived from an algorithm that processes previous historical data from moving objects traveling on the same route.

Abstract: System and method for determining location-enhanced presence information for a particular entity subscribed to a communications system. Location information indicative of a current location for the particular entity is obtained, as well as presence information indicative of a current activity status of the particular entity within the communications system. A combination of the current location and current activity status of the particular entity is applied as a condition to a set of conditional rules associated with the particular entity, for determining current location-enhanced presence information for the particular entity.

Abstract: The rate at which a particular wireless client may be PINGed may depend on many factors, including the accuracy with which the location of the wireless client is required to be known, how accurate the system has historically been able to locate other previous clients in the same general area; the speed with which the client is moving, the amount of other data being transmitted by the client, the needs of other clients being serviced by the access point that will need to PING the client, the current battery life of the client, and the priority of obtaining an accurate location for a particular wireless user verses other uses of the network bandwidth. Based on the multiple factors considered by the system, the rate at which the client will be PINGed is adjusted to optimize the amount of bandwidth used to determine the client's location.

Multiple power management devices allow for a sensor network of fixed or mobile wireless sensing nodes or sensor gateways to make use of power from an external source such as an another network. An intelligent power management device connected to at least one of the sensing nodes may provide for power policy management.

Abstract: A method and system for managing handover where a database that receives location information about a moving object includes information regarding which base station is used in a current radio link connection and which base stations were used from historic radio link connections. Using the base station radio link history of the object and an electronic map, a processor coupled to the memory of the database selects which physical path the moving object is using. Upon matching the object's path with a history of path routes on the list, the processor will apply an optimized handoff sequence to the moving object. The optimized route can be derived from an algorithm that processes previous historical data from moving objects traveling on the same route. Methods of providing the location of moving objects via location sensors may be used to provide the database with higher resolution information about a moving object's location on an electronic map and allow further enhancement of the handoff optimization.

Abstract: The present invention relates to a system and method for providing power management to sensing nodes in a sensor network. A system may include a plurality of sensing nodes, each sensing node connected through a power management device to an external power source, such as a powered node of another network, for managing power from the external power source to the sensing node. Beneficially, a plurality of power management devices allow for a sensor network of fixed or mobile wireless sensing nodes or sensor gateways to make use of power from an external source such as an another network e.g. an existing emergency lighting system or other similar powered building system. Thus for example, a sensor or group of sensing nodes and their associated power management devices may be integral with or co-located in proximity to powered nodes of these other networks.

Abstract: A method of controlling RF interference in a healthcare establishment. The method comprises receiving data regarding a wirelessly detectable tag associated to a first piece of equipment within the healthcare establishment; determining whether the first piece of equipment is positioned relative to a second piece of equipment within the healthcare establishment such that an RF interference constraint is violated, based at least in part on the data regarding the wirelessly detectable tag; and responsive to the RF interference constraint being violated, causing a variation in RF power transmitted by at least one of the first piece of equipment and the second piece of equipment. In this way, wireless communication equipment can be used in the healthcare establishment without deleterious effects on sensitive medical equipment.

Abstract: Information may be extracted from an array of relatively low sensitivity hazardous material sensors deployed, for example within a population center, by collecting identification information, such as video data, RFID data, proximity data, and IR data along with the hazardous material sensor reading. The identification information may then be used to identify objects in the vicinity of the hazardous material sensor at the time the reading was taken. By using identification data to identify an object, and then correlating sensor data readings for that object with other sensor data readings for the same object, as identified using previously collected identification information, a statistically more significant reading may be obtained for that particular object than would be obtainable by any one particular hazardous material sensor. Optionally the proximity of the object to the sensors may be used to weight the readings from the sensors.
