Mobile phones are rapidly becoming the universal access point for computing, communication, and digital infrastructures. In this paper we explore the software architectures necessary to make the mobile phone a truly universal access point to any electronic infrastructure. We propose AlfredO, a lightweight middleware architecture that allows developers to construct applications in a modular way, organizing the applications into detachable tiers that can be distributed at will to dynamically con\ufb01gure multi-tier architectures between mobile phones and service providers. Through AlfredO, a phone can lease on-the-\ufb02y the client side of an application and immediately become a fully tailored client. Our experimental results indicate that AlfredO has very little overhead, it is scalable, and yields very low latency. To demonstrate the feasibility and potential of the platform, in the paper we also describe AlfredOShop, a prototype application for spontaneously controlling information screens from a mobile phone.<\/p>\n","protected":false},"excerpt":{"rendered":"
