ABSTRACT:
A method and apparatus for assigning a unique network address to a first node within a network which is arbitrarily connected. The first node may include a shared network resource, such as a networked printer device, or a modem, in addition to a stand-alone computer system. The network may include a network which is wireless, wherein various nodes comprise radio transceiver circuitry, including radio frequency modems. A first provisional network address for use in assigning the unique network address is determined by the first node. The first node broadcasts probes containing the provisional network address until a first probe response to one of the probes is received or a first interval of time elapses. If the first probe response to one of the probes is received, then the first node determines a second provisional network address and repeats selection of the address and broadcasting, until no probe response is received in the first interval of time. Using the first provisional network address, the first node broadcasts forward probes in the network until a second probe response to one of the forward probes is received by the first node or a second period of time has transpired. If a second probe response to one of the forward probes is received by the first node, then the first node determines a third provisional network address and repeats the steps of selecting, broadcasting probes and forward probes until no the response is received in the second interval of time. The final provisional network address may be used as the unique network address for the first node.
