Apparatus, method, and medium for self-organizing multi-hop wireless access networks
First Claim
1. A wireless computer network, comprising:
- a wireless backbone network which includes at least one wireless network node device which operates as a master authentication node, and wireless network node devices which provide wireless local access service to mobile client computer devices in their coverage area and operate as proxy authentication nodes, and which forwards and delivers communication data of mobile client computer devices in multihop fashion, said wireless computer network being characterized in that;
wireless network node devices which newly join as part of said wireless backbone network enabled to act as a supplicant to request authentication from said wireless backbone network prior to becoming part of said wireless backbone network;
a wireless network node device which has received said authentication request is enabled to operate as a proxy authentication node to request authentication processing from a wireless network node device which operates as said master authentication node; and
a new wireless network node device initiates wireless local access service to said client computer devices within its coverage area after joining said wireless backbone network using a key for joining said wireless backbone network provided after completion of authentication, and operates as a proxy authentication node for authentication requests from wireless network node devices newly joining said wireless backbone network.

Abstract
A wireless computer network includes a backbone network including backbone network nodes authenticated to each other and in communication with each other. The wireless computer network also includes a master authenticator node and a proxy authenticator node among the backbone network nodes. When an unauthenticated new node requests authentication to the backbone network and the unauthenticated new node is in communication with at least one of the backbone network nodes, the at least one of the backbone network nodes becoming the proxy authenticator node for the unauthenticated new node and communicates with the master authenticator node to authenticate the unauthenticated new node to the backbone network.

6. A method for a wireless computer network, comprising:
-
providing a wireless backbone network which includes at least one wireless network node device which operates as a master authentication node, and wireless network node devices which provide wireless local access service to mobile client computer devices in their coverage area and function as proxy authentication nodes, and which forwards and delivers communication data of mobile client computer devices in multihop fashion; enabling wireless network node devices which newly join as part of said wireless backbone network to act as a supplicant to request authentication from said wireless backbone network prior to becoming part of said wireless backbone network; causing a wireless network node device which has received said authentication request to operate as a proxy authentication node and request authentication processing from a wireless network node device which operates as said master authentication node; initiating, via a new wireless network node device, a wireless local access service to said client computer devices within its coverage area after joining said wireless backbone network using a key for joining said wireless backbone network provided after completion of authentication, and causing the new wireless network node device to operate as a proxy authentication node for authentication requests from wireless network node devices newly joining said wireless backbone network. - View Dependent Claims (7, 8, 9)
