Communication method, radio AD-HOC network, communication terminal, and bluetooth terminal
First Claim
1. A communication method for a group communication, the method forming a predetermined cluster among a plurality of radio stations and selecting a cluster head managing the cluster, comprising the steps of:
- operating one of the radio stations belonging to the cluster as a tentative cluster head;
determining the communication efficiency when the radio station becomes the tentative cluster head; and
selecting a cluster head in the cluster among the radio stations composing the cluster based on the determined communication efficiency.

Abstract
A network communication is performed automatically and in an optimal manner in radio ad-hoc communications. A communication terminal is configured to serve as one of a plurality of nodes composing a cluster as well as serve as a cluster head that allows communication with remaining nodes of cluster members and includes: a unit 11 for determining aptitude degree as cluster head that comprehends communication conditions with the cluster members; unit 12 for creating schedules for change of cluster head that creates schedule tables 15 to circulate the cluster members in order as a tentative cluster head; a unit 21 for monitoring aptitude degree of communication conditions that recognizes communication conditions with other nodes when the cluster member becomes the tentative cluster head; and a unit 26 for reconfiguring cluster that reconfigures the cluster based on the comprehended communication conditions and the recognized communication conditions.

5. A radio ad-hoc network composing a cluster that is composed of a node of a cluster head and one or more nodes of cluster members, wherein
the node of the cluster head comprehends its own communication conditions with the nodes of the cluster members and generates a schedule for change of the cluster head based on the communication conditions and distributes the schedule to the nodes of the cluster members; - and
the nodes of the cluster members comprehend their own communication conditions with the nodes composing the cluster based on the distributed schedule and send the communication conditions to the node of the cluster head. - View Dependent Claims (6, 7)

8. A radio ad-hoc network composing a cluster that is composed of a node of a cluster head and one or more nodes of cluster members, wherein
the cluster head distributes a schedule that determines a circulation operation of a tentative cluster head on the cluster members that compose the cluster; - and
the cluster members comprehend as a tentative cluster head their communication conditions with other nodes based on the distributed schedule and sends the communication conditions to the cluster head, wherein the cluster members can become a new cluster head based on the delegation of authority from the cluster head. - View Dependent Claims (9)

15. A communication terminal that can be configured as one of a plurality of nodes composing a cluster as well as serve as a cluster member that allows communication with other nodes of cluster head, comprising:
-
means for receiving a circulation schedule to determine an aptitude degree as a cluster head from the cluster head;
means for comprehending communication conditions with other nodes composing the cluster based on the received circulation schedule; and
means for sending the comprehended communication conditions to the cluster head.

16. A Bluetooth terminal that can be configured as one of a plurality of radio stations composing a piconet as well as manage a plurality of slaves as a master, comprising:
-
means for comprehending communication conditions with the plurality Of slaves; and
means for delegating authority as a master to a predetermined slave composing the piconet to reconfigure the piconet if it is determined to be inappropriate as a master from the comprehended communication conditions.
