In a multi-access and multi-service 802.11 environment, the problem of providing users with useful service-related information to support a correct, rapid network selection is expected to become a very important issue. This paper proposes a feasible, short-term 802.11-tailored solution for service publishing. This makes it possible for an operator to implement service publishing in 802.11 networks while waiting for a standardized mechanism. The paper presents a quantitative comparison of service discovery times between the legacy scenario, where the user is forced to associate and authenticate with a network point of access to check its service offer, and the enhanced scenario where the set of service-related information is broadcasted within beacons.
