The three node devices 1 including the self are selected by participating in the cluster that the device communication unit D of the own device participates in based on the beacon received from the other node devices 1 and broadcast transmission to the first node device 1 and the like. Control to link. Specifically, in the case of the node device 1a, based on the received beacon, one device communication unit D creates a cluster constructed by the node device 1b corresponding to the condition that the three node devices 1 including itself are connected. Select and participate to link the three node devices 1a, 1b, and 1c including the self, and based on the received beacon, the other device communication unit D includes the three node devices 1 including the self as a condition to form a link. The cluster constructed by the corresponding node device 1d is selected and joined, and the three node devices 1a, 1b, and 1d including itself are linked. Here, the node device 1 finds an arbitrary cluster constructed by another node device 1 to which the node device 1 is not connected, when an appropriate cluster in which the three node devices 1 including the device itself are connected is not found.

上記実施形態において、通信ネットワークシステムは、クラスタを構築するホスト通信部Hまたはクラスタに参加するデバイス通信部Dを備える各ノード装置1を備え、デバイス通信部Dがクラスタに参加してクラスタ内通信を行う網目状の通信ネットワークを構築し、2つまたは3つのクラスタにより、3つのノード装置1のみで連環する部分を備えることを特徴としてもよい。また、ノード装置1において、自己が構築したクラスタと自己が参加した他のクラスタの識別情報を他のノード装置1に通知する手段と、該他のノード装置1から識別情報を取得し自己を含む3つのノード装置1を連環させる様に自己が他のクラスタに参加する手段を備えることを特徴としてもよい。また、ノード装置1、周辺装置2、IP端末3がホスト通信部H、スイッチ部S、デバイス通信部Dなどを備えた通信用集積回路を備え、該通信用集積回路によりホスト通信部H、スイッチ部S、デバイス通信部Dなどが制御されてノード装置1、周辺装置2、IP端末3を実現する構成としてもよい。また、ノード装置1が通信ネットワークの端末を構成していてもよい。また、ノード装置1、周辺装置2、IP端末3としてワイヤレスUSBを用いた装置を用いたがノード装置1、周辺装置2、IP端末3を、ワイヤレスUSBを用いた装置を問わず、例えば、特開2010−263349号公報の端末装置と同様の構成などとしてもよい。また、同一エリア内でクラスタの乱立を防ぐために、各ノード装置1が同一エリア内のクラスタの数に応じて、IP端末3として機能するようにしてもよい。 In the above embodiment, the communication network system includes each node device 1 including the host communication unit H that constructs the cluster or the device communication unit D that participates in the cluster, and the device communication unit D participates in the cluster and performs intra-cluster communication. A network-like communication network to be performed may be constructed, and two or three clusters may include a portion that is linked only by three node devices 1. Further, in the node device 1, means for notifying the other node device 1 of the identification information of the cluster constructed by itself and the other cluster in which the self participates, and acquiring the identification information from the other node device 1 and including the self It is also possible to provide means for self to join another cluster so that the three node devices 1 are linked. Further, the node device 1, the peripheral device 2, and the IP terminal 3 include a communication integrated circuit including a host communication unit H, a switch unit S, a device communication unit D, and the like. The node device 1, the peripheral device 2, and the IP terminal 3 may be realized by controlling the unit S, the device communication unit D, and the like. The node device 1 may constitute a communication network terminal. In addition, although devices using wireless USB are used as the node device 1, peripheral device 2, and IP terminal 3, the node device 1, peripheral device 2, and IP terminal 3 are not limited to devices using wireless USB. It is good also as a structure similar to the terminal device of gazette 2010-263349. Further, in order to prevent cluster clustering in the same area, each node device 1 may function as the IP terminal 3 according to the number of clusters in the same area.
さらに、通信ネットワークシステムは、各ノード装置1がツリー状に接続されていてもよい。また、各ノード装置1がフロアコンセント、屋内の天井などの照明装置、該照明装置に設置されたLED電球やLED蛍光管などの管球類、監視カメラや監視センサなどの監視装置、或いは消防設備の誘導灯や非常用照明器具や感知器(例えば、熱感知器や煙感知器やガス漏れ感知器)などを形成すると、それらが人の立ち入る場所にクラスタの空白エリアを作らないように所定の間隔で固定設置されていることから、クラスタの空白エリアを解消することが可能となる。また、一部のノード装置1を400Gbpsや1TbpsのEthernet(登録商標)を実現するサブ光コネクタを形成する光ファイバの光接続構造(特許5237487号など)を備えた電気コンセントに接続し、光LANの端末と通信ネットワークシステムの端末を構成するテレビジョンやパーソナルコンピュータなどとすると、モバイルを構成するIP端末3が各ノード装置1のクラスタ間をハンドオーバーしながらインターネットに接続することが容易となる。また、同一エリア内でクラスタの乱立を防ぐために、各ノード装置1が同一エリア内のクラスタの数に応じて、ノード装置1としての機能を停止するようにしてもよい。 Furthermore, in the communication network system, the node devices 1 may be connected in a tree shape. In addition, each node device 1 is a floor outlet, a lighting device such as an indoor ceiling, a tube such as an LED bulb or LED fluorescent tube installed in the lighting device, a monitoring device such as a monitoring camera or a monitoring sensor, or a fire fighting facility Guide lights, emergency lighting fixtures and detectors (e.g. heat detectors, smoke detectors, gas leak detectors), etc., do not create cluster blank areas where people enter. Since it is fixedly installed at intervals, it becomes possible to eliminate the blank area of the cluster. Also, some of the node devices 1 are connected to an electrical outlet provided with an optical fiber optical connection structure (such as Japanese Patent No. 5237487) that forms a sub optical connector for realizing 400 Gbps or 1 Tbps Ethernet (registered trademark). If the terminal of the communication network system is a television or a personal computer, it becomes easy for the IP terminal 3 constituting the mobile to connect to the Internet while handing over the clusters of the node devices 1. Further, in order to prevent cluster clustering in the same area, each node device 1 may stop functioning as the node device 1 in accordance with the number of clusters in the same area.
上記実施形態によれば、通信ネットワークシステムは、周辺装置2が任意のクラスタに参加し、通信ネットワークを介して任意のノード装置1の周辺装置として機能することができる。また、各ノード装置1が人の立ち入る屋内に固定設置され、該屋内でクラスタの空白エリアを作らないようにクラスタを構築し、IP端末3がノード装置1間をハンドオーバーすることが可能であり、特に、支持部や電源供給側とコネクタで接続される管球類や監視装置や感知器などの容易に交換することが可能な製品を各ノード装置1とすると、従来品との交換で容易にアドホックネットワークを構築することができる。 According to the embodiment, the communication network system can function as a peripheral device of any node device 1 via the communication network, with the peripheral device 2 participating in any cluster. In addition, each node device 1 is fixedly installed indoors where people enter, and it is possible to construct a cluster so that a blank area of the cluster is not created indoors, and the IP terminal 3 can be handed over between the node devices 1. In particular, if each node device 1 is a product that can be easily replaced, such as a tube connected to the support unit or the power supply side with a connector, a monitoring device, or a sensor, it can be easily replaced with a conventional product. An ad hoc network can be constructed.
