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.
