Person-level routing in the mobile people architecture

摘要: Ubiquitous network connectivity for devices does not automatically imply continuous reachability people. People move from place to and switch one device another. As a result, phones ring in empty offices, email cannot reach most cell phones, spam clogs expensive, low-bandwidth links laptops. Whereas existing mechanisms have addressed host mobility or the of people within network, few allowed people, ultimate important endpoints communication, roam freely, without being constrained location, application, device, network. We designed Mobile Architecture (MPA) maintain person-to-person reachability. The central component MPA is person-level router called Personal Proxy. It tracks mobile person's accepts communications on his behalf, converts them into different application formats according preferences, forwards resulting him. In contrast similar systems, Proxy protects user's privacy, easily extensible new applications, has been deployed with no modifications telecommunications infrastructure. this paper, we describe design, implementation, preliminary evaluation our prototype Proxy, service that integrates Internet telephone communication addresses need
