Abstract: A method to reduce group reformation time and maintain seamless connectivity in a peer-to-peer network at the time of disappearance of the Group Owner (GO). Each of the nodes is provided with an emergency leader list which prioritizes a predetermined number of emergency leader nodes each of which is a client node having intent of acting as an emergency leader, wherein the emergency leader list is prepared right at the time of group formation. The emergency leader nodes broadcast beacons when a leader node disappears from the group without notice. Each of the client nodes barring a first-priority emergency leader node of the emergency leader list connects to a highest priority one of emergency leader nodes detected by the client node.

Abstract: 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.
Abstract translation: 与通信网络未连接的第一通信终端搜索存在于自身通信终端周围的第二通信终端。 在通信网络中，多个通信终端之一用作具有接入点功能的主机，其余的通信终端用作主机的从机。 基于从通过搜索发现的一个或多个第二通信终端接收到的通信消息中包含的信息，第一通信终端确定用作第二通信终端中的连接对方的第二通信终端，并且配置通信网络 确定的连接对应。

Abstract: A delivery node alternately connects to a first wireless terminal and a second wireless terminal. When a first packet with a virtual IP address of the second wireless terminal as a destination IP address is output from a first application to a virtual network interface, the first wireless terminal encapsulates the first packet with the use of an encapsulation header and transmits to the delivery node. The delivery node encapsulates the first packet obtained by decapsulating the received encapsulation packet again, and transmits to the second wireless terminal. The second wireless terminal transmits the first packet obtained by decapsulating the received encapsulation packet to a second application through a virtual network interface.

Abstract: In the present invention, a wireless communication network includes a plurality of nodes which can form P2P (peer-to-peer) groups and are capable of performing wireless communications using a first communication method and wireless communications using a second communication method. A first owner node (GO node) that operates as a first P2P group access point transmits a message for requesting delivery node connection preparations to a second GO node that operates as a second P2P group access point present in a neighborhood by wireless communication using the second communication method, and selects, as a delivery node, one or a plurality of client nodes belonging to the first P2P group. The delivery node is disconnected from the first P2P group and is connected to the second P2P group, and information is transferred between the delivery node and the second GO node.
