Abstract
Service discovery for services on a wireless network is presented. It is determined (e.g., from a received Layer 2 message) that an offering apparatus h made a service available to entities joined to a wireless network. Then in a message, that is available to entities not joined to the network, is placed information about the services and also at least one of location information about the offering apparatus and link metric information about a network path to the offering apparatus. A discovering apparatus reads one or more transmitted messages (from different apparatuses in the same network in different networks), sees the service it wants is available through both, compares the different locations and/or the different link metrics, and based on the comparing chooses which network to join, or with which apparatus on the single network to create a peer link.
