Abstract:
A system and method for managing a multi-user environment is disclosed. The system is configured to assign at least one server for each client device. The system enables to create at least shard for each user by at least one of the client devices and the server. Each shard encapsulates one or more volumetric spaces and forms at least a portion of the simulation environment. The system is configured to create a finite number of shards for every given area at any given moment. The shards are dynamically selected or created through negotiations between the client device and the server at real time. The shard design (volume and content) is dynamically configured to provide best experience for the client device at the simulation environment.

Systems and methods are described for determining trustworthiness. The systems and methods may include obtaining a plurality of nodes associated with a first entity, wherein the plurality of nodes correspond to a plurality of additional entities, each the plurality of nodes being defined by both a trust metric and a relationship indication to the first entity or to another of the plurality of additional entities; generating a model of the plurality of nodes based on the trust metric and the relationship indication to the first entity or to another of the plurality of additional entities; and generating, based on the generated model, an application programming interface (API) for accessing and modifying a representation of the model according to one or more selectable contexts or attributes associated with one or more of the plurality of nodes.

The systems and methods may perform obtaining a plurality of nodes associated with a first entity, wherein the plurality of nodes correspond to one or more additional entities, each of the one or more additional entities being defined by a trust metric, a relationship indication, and at least one activation function, generating, for each of the plurality of nodes, an output by executing each activation function according to a set of predefined rules defined for the plurality of nodes, wherein each activation function uses a respective trust metric defined for the one or more additional entities, and generating a model for determining trustworthiness of the first entity based on each relationship indication and the output for each of the plurality of nodes.
Abstract:
Multiple-configuration communication apparatus includes: a communication device (130) simultaneously maintaining at least a first and a second channel; a storage device (114, 116, 118) storing a plurality of communication configurations; and a configuration controller (120) determining a first time frame and during the first time frame, selecting a first communication configuration of the plurality of communication configurations and controlling the communication device to configure itself to the first communication configuration to at least one of transmit and receive information over the first channel, and determining a second time frame that is different from the first time frame and during the second time frame, selecting a second communication configuration of the plurality of communication configurations, and controlling the communication device to configure itself to the second communication configuration to at least one of transmit and receive information over the second channel.
Abstract:
A method and system for wireless data transmission between at least three stations use multiple frequency bands for simultaneous channel communications. The method includes transmitting a Request To Send (RTS) packet from a first station to an intermediate second station over a first frequency band. Two Clear To Send (CTS) packets, which CTS packets include transmission timing information, are then transmitted from the second station simultaneously both to the first station and to a third station. The CTS packet sent to the first station is transmitted over the first frequency band and the CTS packet sent to the third station is transmitted over a second frequency band. A data packet from the first station is then transmitted to the second station. The third station suspends, based on the transmission timing information included in the CTS packets, any unicast transmission to the second station during the transmission of the data packet from the first station to the second station.
Abstract:
A method and apparatus for facilitating a fast handoff for subscribers in a Wireless Metropolitan Area Network (WMAN) by establishing a hard association with a first entity by sending a hard association request to the first entity and receiving a hard association response in response to the hard association request and establishing a pending association with a second entity by sending a pending association request to a second entity and receiving a pending association response from the second entity. In one embodiment, the pending association with the second entity may be converted to a hard association.
Abstract:
A method for enabling asset tracking that includes the steps of: receiving (910) a first excitation signal at a first power level using a first frequency band; and (920) upon determining that a first set of parameters is satisfied, awakening from an inactive mode to an active mode, transmitting data at a second power level that is greater than the first power level using a second frequency band that is different from the first frequency band, and returning to the inactive mode, wherein determining that the first set of parameters is satisfied comprises at least determining that the first excitation signal corresponds to a first wake-up circuit.

Abstract:
A communication network (10) utilized for providing communications between a first party and a second party includes a surveillance server (26) within a core network (10) to provide communication surveillance capability. The core network (10) may be a packet data network, and the surveillance server (26) is operable responsive to trigger information to establish communications surveillance. Communication surveillance may be established by creating duplicate bearer packets of those data packets carrying the communicated data between the parties, creating duplicate control packets of those data packets carrying in-band or out-of-band call control information between the parties and within the packet data network, and/or various combinations thereof. The duplicate bearer packets and the duplicate control packets are routed to appropriate authorized law enforcement agencies for providing surveillance.
