Wireless networks play a major role in allowing the deployment of ubiquitous distributed systems. In these networks, service discovery should not only allow finding available networked services, but should also take into account the physical proximity of the entities requesting these services.
However, physical proximity is not a sufficient criteria for service search and selection, as close attention should be paid to privacy issues. In this paper we present the design issues that should be considered in order to properly support service discovery based on the physical location of clients; these issues are taken into account for the proposal of an architecture for context-aware distributed systems that consider privacy concerns8th IFIP/IEEE International conference on Mobile and Wireless CommunicationRed de Universidades con Carreras en Informática (RedUNCI
