20090034546 | PACKET ROUTING CONTROL METHOD AND SYSTEM - A wireless communication system downloads information from a file server quickly and efficiently by using multiple wireless communication paths. When a destination requests data from a file server through a wireless terminal, the wireless terminal generates an address translation rule that includes source, translation and destination addresses used to route the data from the file server to the destination through a virtual network server. The address translation rule is sent to at least one other wireless terminal, so that retrieved data packets can be routed through both wireless terminals simultaneously. A packet retrieved from the file server is sent to the virtual network server, where the packet is encapsulated into multiple packets and assigned virtual addresses. The encapsulated packets are sent to the multiple wireless terminals, and are sent from those terminals to the destination using the address translation rule, where the packets are decapsulated to reproduce the originally sent packet. | 02-05-2009 |
20090046729 | ROUTING CONTROL METHOD AND SYSTEM - A VPN server encapsulates a packet P | 02-19-2009 |
20090323654 | WIRELESS AD HOC COMMUNICATION SYSTEM - A communication terminal performs wireless ad hoc communication with another terminal via a first wireless interface dedicated to reception and a second wireless interface for both transmission and reception. The terminal executes defining a communication area to be divided into cells of first polygonal shapes and each of the cells to be divided into a plurality of sub-cells of second polygonal shapes different from the first polygonal shapes; allocating, so as to prevent adjacent cells from belonging to a set of two identical wireless channels, a first wireless channel and a second wireless channel as the set of wireless channels to the cells; and setting the first wireless channel and the second wireless channel so that the same transmission channel is set for sub-cells brought into contact between the adjacent cells while different transmission channels are set for adjacent sub-cells in an own cell where an own terminal is present. | 12-31-2009 |
20100182925 | RADIO COMMUNICATION APPARATUS - A radio communication apparatus including: a receiver receiving a traffic evaluation index value of a contention node as a connection node one layer below a self node with a root node of a radio network set as the top layer; parameter determining unit determining a parameter related to priority control of the contention node or a priority for determining the parameter, based on the traffic evaluation index value of the contention node, so that a traffic congestion is prevented and cleared; and a transmitter transmitting the parameter related to the priority control of the contention node or the priority to the contention node. | 07-22-2010 |
20110078777 | Computer-readable recording medium recording remote control program, portable terminal device and gateway device - A computer-readable recording medium which records a remote control program for allowing data on a network protected by a gateway device to be transferred to an external device by external remote-control operations; a portable terminal device; and a gateway device. The terminal device transmits to the gateway device an access ticket issue request. The gateway device generates key information and transmits to the terminal device an access ticket including the key information. The terminal device transfers to a data acquisition device a data acquisition instruction including the acquired access ticket. The acquisition device transmits to the gateway device a data request including the key information. When the key information added to the access ticket and the key information included in the data request are the same, the gateway device transfers the data request to a data server device. The server device transfers the data to the acquisition device. | 03-31-2011 |
20130229911 | WIRELESS COMMUNICATION DEVICE AND METHOD FOR SEARCHING FOR BYPASS ROUTE IN WIRELESS NETWORK - A wireless communication device comprising: a storage configured to store identification information identifying a particular adjacent device from among the plurality of wireless communication devices that is adjacent to the wireless communication device and that transmits, to the wireless communication device, data addressed to a final destination device; a generator configured to generate search data that includes information indicating a search of a route to the final destination device; a transmitter configured to broadcast the search data to adjacent devices; and a decision unit configured to determine that a bypass route from the particular adjacent device to the final destination device is not present when data that includes information indicating that the search data does not reach the final destination device is received from all particular adjacent devices for which identification information is stored in the storage. | 09-05-2013 |
20130242806 | GATEWAY APPARATUS, NODE APPARATUS, COMMUNICATION SYSTEM, CONTROL METHOD AND COMPUTER READABLE MEDIUM - A gateway apparatus that connects a multi-hop network of tree structure formed of node apparatuses to other network, comprising a grouping unit that groups, for each representative node apparatus having a direct link to the gateway apparatus in the tree structure, the nodes belonging to a subtree having same representative node as a root, into a node group, an interference group specifying unit that specifies a node group in which packet communication in the node group is subjected to an interference of a degree exceeding a threshold as an interference group, and a slot allocation unit that allocates some one time slot among a plurality of time slots included in a frame to one interference group among a plurality of interference groups, and allocates another time slot among the plurality of time slots to another interference group among the plurality of interference groups. | 09-19-2013 |
