Patent number: 9179461Abstract: A wireless communication device in a wireless network sets management information notification cycles at specified time intervals and transmits management information containing receive timing information showing its own position to start receiving information, receive window information, and receive cycle information. Another wireless communication device receiving that management information links it to a communication device number for the corresponding wireless communication device and stores the receive timing, the receive window information, and the receive cycle information. When sending information, the receive start position of the corresponding communication device is found from the receive timing information, the receive window information, and the receive cycle information of the other communication and information is then transmitted at that timing. An asynchronous ad-hoc communication wireless network can therefore be configured without a particular control station.Type: GrantFiled: April 20, 2012Date of Patent: November 3, 2015Assignee: Sony CorporationInventor: Shigeru Sugaya

Patent number: 9042355Abstract: A device stores a traffic management profile for satellite network traffic that provides default percentages for classes of traffic that can pass when contention for limited bandwidth exists. The device receives packets having class markings and designated for transmission over a Demand-Assigned Time Division Multiple Access (DA-TDMA) network and identifies each of the received packets as one of a transmission control protocol (TCP) packet or a non-TCP packet. The device assigns the received packets to different queues based on the class markings and the identifying as a TCP packet or non-TCP packet, and determines available transmission bandwidth for a particular time slot of the DA-TDMA network associated with the device.
