Person-level Routing in the Mobile People Architecture

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