摘要： The present invention provides a communication method in a wireless communication network in which a first wireless terminal establishes a peer-to-peer wireless connection with a second wireless terminal. The first terminal determines whether or not the second wireless terminal is a universal terminal on the basis of information received from the second wireless terminal. The first wireless terminal controls access to a resource in the first wireless terminal by the second wireless terminal after a connection is established in accordance with the result of the determination.

摘要： A mechanism which can achieve enhanced network performance in wireless P2P groups is disclosed. A method for group reformation in wireless peer-to-peer (P2P) networks, includes: monitoring traffic of a first device of a first P2P group, the first device communicating with a second device of at least one second P2P group; and altering group formation of the first and second P2P groups so as to put the first device and the second device together in a single P2P group, based on monitored traffic of the first device.

摘要： Provided is an information processing device which is capable of suppressing a deterioration in accuracy of detecting an anomaly and accuracy of analyzing the anomaly, while suppressing an increase in an amount of data to be stored. The information processing system includes anomaly detection unit that collects event data indicating a predetermined event detected in a process of a device to be monitored, determines whether a predetermined index value related to the event exceeds a preset first threshold, and instructs enhanced monitoring of the device to be monitored and the process related to the event when the index value exceeds the first threshold, and collection instruction unit that determines an additional event being an event to be additionally monitored when the enhanced monitoring is instructed, and instructs the device to be monitored, which is subjected to the enhanced monitoring, to monitor the determined additional event.

摘要： A communication method, a communication system, a wireless terminal, and a wireless control method are provided that make it possible to share information between terminals without forming a group. In a communication method in a wireless communication network including a plurality of terminals (N1 to N3), a first terminal (N1) and a second terminal(N2 or N3) that belong to different groups, or do not belong to a group, can embed arbitrary information in a control frame (101) that is sent and received to search for a terminal or another group in vicinity, and notification information (MSG) of one of the terminals is notified to the other terminal by using the control frame.

摘要： A connection method in a wireless peer-to-peer group of nodes, wherein one of the nodes acts as a leader and others act as clients of the group, includes the steps of: sending credential information required for creating a virtual persistent group configuration from the leader to each of the clients; creating a virtual persistent group configuration at each of the clients which has received the credential information from the leader; and when leadership of the leader disappears, establishing a first-time connection between a first client and a second client based on persistent mechanism by invitation using the virtual persistent group configuration.

摘要： A mechanism by which the number of groups can be reduced in a multi-group P2P network is disclosed. A method for group formation in wireless peer-to-peer (P2P) networks, includes: exchanging group-related information between group owners of neighboring P2P groups; deciding on whether a combined group of the neighboring P2P groups meets a predetermined condition of either of the neighboring P2P groups, based on the group-related information of the neighboring P2P groups; and merging the neighboring P2P groups to form at least one single group when the combined group meets the predetermined condition.

摘要： A first communication terminal, unconnected with a communication network, searches for a second communication terminal existing around the own communication terminal. In the communication network, one of a plurality of communication terminals functions as a master having a function of an access point, and the rest of the communication terminals function as slaves of the master. Based on the information included in a communication message received from one or more second communication terminals found through the search, the first communication terminal determines a second communication terminal which serves as a connection counterpart from among the second communication terminals, and configures a communication network with the determined connection counterpart.

摘要： A communication terminal has a wireless communication part and a control part. The control part sequentially switches a plurality of communication channels and discovers another communication terminal existing around the communication terminal itself. In the case of connecting to the other communication terminal found in the discovery, the control part determines which of the communication terminals transmits a connection request. In a case where the communication terminal itself does not transmit a connection request, the control part stops the discovery process and waists for reception of a connection request from the other communication terminal by using a given communication channel.
