Abstract

A method of configuring an ad-hoc wireless network between an authenticator and a plurality of wireless devices seeking authentication includes assigning a wireless device as the authenticator and receiving a first setup message transmitted from a first device seeking authentication to the authenticator and initiating a first handshake process between the authenticator and the first device seeking authentication. The method also includes receiving a second setup message transmitted from a second device seeking authentication to the authenticator. The second setup message is received by the authenticator prior to completion of the first handshake process. The method further includes initiating a second handshake process between the authenticator and the second device seeking authentication. The second handshake process is initiated prior to completion of the first handshake process. Moreover, the method includes completing the first handshake process and completing the second handshake process.
