Abstract: An approach for assigning IP network addresses and for performing name resolution and service discovery in infrastructure mode and/or ad-hoc mode peer-to-peer networks. The size of an ad-hoc network and/or the size of infrastructure network basic service sets may be limited to a selected number of peer stations. A first portion of an IP network address assigned to stations joining a network may be predetermined by the network to be joined and a second portion of the IP network address may be selected dynamically, as each new station joins the network. Stations may generate layer 2 messages that include an information element containing information that supports peer-to-peer service discovery, name resolution and IP network address assignment across multiple ad-hoc and infrastructure networks. A peer-to-peer station may dynamically connect to available ad-hoc or infrastructure networks to access required services, as needed.

Abstract: A station associates with an access point in a wireless local area network conforming to, e.g., an IEEE 802.11 standard. The station measures the signal-to-noise ratio (SNR) for the downlink from each of the access points sending either a beacon or a probe response, and forms a first list of access points in decreasing order of received downlink SNR. The station transmits a link test request to each access point to query the access point for the SNR of the link test request received at the corresponding access point. Access points respond to the link test request with corresponding link test responses containing the corresponding SNR. The station i) forms a second list of access points in decreasing order of received uplink SNR and ii) compares the first and second lists to determine which access point to associate with based on overall quality of the uplink and downlink channels.
