Abstract: Managing aircraft satellite communication data traffic is provided. The method comprises calculating total available satellite communication bandwidth across a number of virtual local area networks (VLANs) of an onboard network of an aircraft and prioritizing data traffic for the VLANs according to a specified traffic priority and quality of service policies. The prioritized data is mapped to a number of unified device routing tables to maximize the available total satellite communication bandwidth and meet the quality of service policies. When data packets are received from the VLANs they are allocated across the total available satellite communication bandwidth based on the mapping. The data packets are then transmitted over a single continuously connected VLAN mapped to a satellite communication link from the aircraft to an end station.

Abstract: Systems, methods, and computer-readable media storing instructions for handling wireless communication in wireless mesh networks are disclosed herein. The disclosed techniques virtualize a portion of the communications within the wireless mesh network by implementing a plurality of virtual routers on a server, each virtual router corresponding to a physical router device within the wireless mesh network. Each physical router device is connected to its corresponding virtual router by a deterministic connection, which may include a wired connection to the server. A virtual communication layer implemented by the server is configured to router inter-router communication between the virtual routers. In some embodiments, each virtual router is implemented within a separate container within a virtual mesh network environment running on the server.

Abstract: Described are methods and devices for communication between local networks and global networks. In some examples, a method comprises storing mapping data for multiple hosts in a global network and in a local network. The method further comprises receiving a first data packet from one of the multiple hosts in the local network. The first data packet comprises a first source address being the local network address of the host in the local network, a first destination address being the local network address of the host in the global network and payload data. The method further comprises determining, based on the mapping data, the global network address of the host in the local network and a global network address of the host in the global network, and sending a second data packet over the global network.

Abstract: Provided are methods and systems for automated location and identification of multiple objects in an aircraft cabin. A method utilizes a wireless client, RFID reader, and camera, which together form a set. Each set is associated with a specific inspection zone in the cabin. The RFID reader determines the presence of a RFID tag in only one zone. Further, the camera captures an image of that zone. A data feedback is generated based on both the image and the RFID reader response. The data feedback is transmitted by the wireless client to a router and is analyzed to determine the presence of the object in the inspection zone and, if present, the identity of the object. The data feedback is associated with the location of the zone in the aircraft cabin, which is known or may be determined using a set of wireless routers positioned throughout the cabin.

Abstract: Mapping the physical location of each sensor of a network of wireless sensors in a configured environment, each sensor being in communication with a server and its database, is achieved by attaching RFID tags to objects in the environment which contain both object-relevant information and the MAC address of sensors proximate to those objects. The locations of the tags on the objects are proxies for the locations of the sensors identified on those tags. By reading the tags and up-loading the read tag information to the database, the association of the sensor and the object is known to the server and can be matched with the configuration of the environment to infer the location of each wireless sensor.

Abstract: The present invention is directed to a method of forming a mobile network using Phased Array Antennas. Mobile nodes search for nodes with which to form a network by either transmitting low level announcement signals on a wide spoiled beam directional antenna at progressively increasing power levels, or by receiving announcement signals using a high-gain, narrow directional beam. Low power announcements are compensated for by processing gain in the receive modem. Nodes randomly decide at each step of the scan whether to transmit or receive. Two control slots in an epoch are used for neighbor discovery. The first control slot is to announce or receive an announcement, and the second control slot is used to acknowledge the receipt of an announcement packet. The neighbor discovery process uses in-band communications. The directional communications permit simultaneous links in close proximity to other links without interference.
