20120246275 | INFORMATION SHARING SYSTEM, COMMUNICATION APPARATUS, CONTROL METHOD AND COMPUTER PROGRAM - An information sharing system is provided with multiple communication devices that wirelessly connect with other communication devices in order to communicate with them without going through an access point. Each communication device has: an internal deduction portion that, using a reception history of notification messages received from the other communication devices, deduces which information is currently being held by each of the other communication devices; a duplication determination portion that determines whether or not the information that is currently being held by another communication device and that was deduced by the internal deduction portion matches information held by its own host device; and an information exchange portion that, when the duplication determination portion determines that the information does not match, transmits a notification message that contains the information held by its own host communication device. | 09-27-2012 |
20130242934 | COMMUNICATION TERMINAL, CHANNEL SELECTION METHOD, AND PROGRAM - A communication terminal, comprises: a wireless communication unit to which a plurality of channels are allocated; a channel status calculation unit that calculates, when one of the plurality of channels is set as a forwarding channel, a capacity that can be used in the one channel by the communication terminal and a capacity that can be used in the one channel by another communication terminal; and a channel selection unit that determines, when one of the plurality of channels is set as a forwarding channel, whether a capacity that can be used in the one channel by the communication terminal satisfies a required bandwidth and determines, when another communication terminal has set the one channel as a forwarding channel, whether a capacity that can be used in the one channel by the another communication terminal satisfies the required bandwidth. | 09-19-2013 |
20130272205 | COMMUNICATION DELAY TIME DERIVATION METHOD, COMMUNICATION TERMINAL AND COMMUNICATION DELAY TIME DERIVATION PROGRAM - There is provided a communication delay time derivation method for calculating a communication delay time depending on a combination of channels set between communication terminals on a communication path in the MCH/IF environment. When selecting a channel to be used for communication in each section on the communication path per section between communication terminals on the communication path, a calculation target section specification means | 10-17-2013 |
20140328338 | ROUTE INFORMATION EXCHANGE METHOD, COMMUNICATION TERMINAL, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM STORING ROUTE INFORMATION EXCHANGE PROGRAM - Upon receiving a routing control message from another communication terminal (B | 11-06-2014 |
20150236867 | NETWORK, NETWORK NODE, DISTRIBUTION METHOD AND NETWORK NODE PROGRAM - Provided is a network node which is capable of achieving both of not excessively increasing the communication load in a network, and avoiding, as much as possible, failure of delivering data to an objective node, which is the distribution destination. The network node includes nonstructural distribution means for distributing data according to a nonstructural distribution in a network in which the nonstructural distribution can be performed, structure-type distribution means for distributing data according to a structure-type distribution using a link for the structure-type distribution established in the network, and selection means for selecting the structure-type distribution means or the nonstructural distribution means as broadcast distribution means by using a predetermined evaluation method, wherein the structure-type distribution means or the nonstructural distribution means selected as the broadcast distribution means by the selection means is used to distribute data in the network. | 08-20-2015 |
20150257142 | METHOD FOR EXCHANGING INFORMATION BETWEEN COMMUNICATION TERMINALS, AND COMMUNICATION TERMINAL - Upon sensing an update of any routing information entry held in a routing information storage unit (A | 09-10-2015 |
20150296529 | DATA SHARING SYSTEM - A request possibility determination unit | 10-15-2015 |
20150304371 | DATA SHARING SYSTEM - A communications terminal (a first communications terminal) that creates a holding list that lists information about remaining data, after the removal from data held by said communications terminal of at least one item of data which is not desired to be shared with another communications terminal (a second communications terminal), and sends said list to the second communications terminal by using a communications message. The second communications terminal determines what data, among the data in the holding list received from the first communications terminal, is not held by the second communications terminal, and sends a request for the determined data to the first communications terminal by using a communications message. The first communications terminal sends the data requested by the second communications terminal to the second communications terminal, by using a communications message. | 10-22-2015 |
