20140022950 | NODE AND LINK FORMATION METHOD - A node receives, from a neighboring node that is a node in the neighborhood, neighboring node information indicating a node that neighbors the neighboring node and determines whether a common neighboring node is present, the common neighboring node being common amongst a neighboring node and a node indicated by the received neighboring node information. When it is determined that the common neighboring node is present, the node registers, in a storage unit, information that a link on a simplex path is to be formed with the common neighboring node or the neighboring node that is the source of the neighboring node information. Alternatively, when it is determined that the common neighboring node is not present, the node registers, in the storage unit, information that a link on a duplex path is to be formed with the neighboring node that is the source of the neighboring node information. | 01-23-2014 |
20140029469 | COMMUNICATION DEVICE AND ROUTE SEARCH METHOD - A node transmits a route search demand, which is a demand to search for a route from the node to a predetermined device among adjacent communication devices, to an adjacent communication device that is not selected as a transmission destination of the route search demand. The node transmits the route search demand when the number of adjacent communication devices serving as confirmed routes is smaller than a predetermined number and when there is an adjacent communication device that has not been selected. The node stops transmission of the route search demand when the number of the adjacent communication devices serving as the confirmed routes reaches the predetermined number. The node transmits a warning to the predetermined device when the number of the adjacent communication devices serving as the confirmed routes is smaller than the predetermined number and when there is no adjacent communication device that has not been selected. | 01-30-2014 |
20140074994 | GATEWAY APPARATUS, COMMUNICATION METHOD OF GATEWAY APPARATUS, NODE APPARATUS, COMMUNICATION METHOD OF NODE APPARATUS, AND COMMUNICATION SYSTEM - A gateway apparatus includes a sorting destination storing unit which stores information of a sorting destination that performs a process according to a destination, a sorting unit which outputs an input destination and transmission data to a sorting destination according to the destination searched from information stored in the sorting destination storing unit, a transmission destination storing unit which stores information of a transmission destination for each destination, an input/output unit which performs a transmission process and a reception process according to a corresponding protocol stack, and a protocol converting unit which assembles, when a destination and transmission data are input from the sorting unit, the destination and the transmission data as data that matches a format of a corresponding protocol stack, and instructs the input/output unit of a corresponding protocol stack to transmit the assembled data to a transmission destination according to the destination. | 03-13-2014 |
20140198770 | NODE DEVICE, COMMUNICATION METHOD, AND STORAGE MEDIUM - Anode device includes a receiver, a processor, memory, and a transmitter. The receiver receives a path information packet for notification of path information about a network. The processor generates a participation request packet for requesting a first node device selected between an adjacent node device and a node device communicable through the adjacent node device to participate in a first local cluster. The memory stores a path to each affiliated node device affiliated with the first cluster. The transmitter transmits the participation request packet to the first node device. When a number of affiliated node devices which are affiliated with the first cluster exceeds a threshold, the processor generates a generation request packet for requesting a second node device which is not affiliated with the first cluster to generate a second cluster different from the first cluster. The transmitter transmits the generation request packet to the second node device. | 07-17-2014 |
20140358967 | SERVICE SEARCH METHOD AND SERVER DEVICE IN DISTRIBUTED PROCESSING - A service search method, judges when receiving a service search request from a service search requester whether or not a local server matches a service search condition stored in the service search request by referring to the attribute about the local server; selects according to the route information a server having no search record in the search history information which is added to the service search request when it is judged that the local server does not match the service search condition, and transfers to the selected server the service search request to which the information about the local server is added as the search history information; and notifies the service search requester of a search request reply according to the route information generated by the local server when it is judged that the local server matches the service search condition. | 12-04-2014 |
20140379777 | DEVICE AND METHOD FOR PERFORMING DISTRIBUTED PROCESSING - A computer-readable recording medium has stored therein a program for causing a computer to execute a process including storing, as a variable set, a database of a variable that associates a key, a value and a synchronization destination corresponding to the key, executing a process of requesting that the variable in the variable set of the computer be referred to or updated in a state and evaluating a condition so as to make the state transition to a different state, and communicating the key specified by the request with the synchronization destination for the variable corresponding to the key specified by the request and synchronizing the value of the variable corresponding to the key in the computer and the value of the variable corresponding to the key in the variable set of the synchronization destination when the process of requesting is executed. | 12-25-2014 |
20150138967 | COMMUNICATION METHOD, COMMUNICATION APPARATUS, AND COMMUNICATION SYSTEM - A communication method for causing a communication apparatus included in a network to perform a process. The method includes: specifying an arrangement of the communication apparatus in the network, using the number of adjacent apparatuses, which are apparatuses adjacent to the communication apparatus, and the number of adjacent apparatuses of each of the adjacent apparatuses; determining the number of times of broadcast of a broadcast frame, using number-of-times-information in which candidates for an arrangement of the communication apparatus in the network and the number of times at which the communication apparatus broadcasts a frame are associated; and broadcasting the broadcast frame the determined number of times. | 05-21-2015 |
20150188669 | COMMUNICATION CONTROL METHOD, NETWORK SYSTEM, AND COMMUNICATION DEVICE - A communication control method to be executed by a communication device, includes: transmitting, to one or more communication devices coupled to the communication device, a packet in which a destination is set; and determining, based on the number of paths that are among paths extending through the one or more communication devices to the destination and through which a response to the packet is received from the destination, the number of times of retransmission in the transmission of another packet to the destination. | 07-02-2015 |
