Communicating with Mobile People
People are the outsiders in the current communications revolution.
Computer hosts, pager terminals, and telephones are addressable
entities throughout the Internet and telephony systems. Human beings,
however, still need application-specific tricks to be identified,
like email addresses, telephone numbers, and ICQ IDs. The key challenge
today is to find people and communicate with them personally, as opposed
to communicating merely with their possibly inaccessible machines---cell
phones that are turned off, or PCs on faraway desktops.
The main goal of the Mobile People and IdentiScape projects is to
put the person, rather than the devices that the person uses, at the
endpoints of a communication session. The Mobile People Architecture
introduces the concept of routing between people. To that effect,
we define the Personal Proxy, which maintains the list of devices
or applications through which a person is currently accessible and
dispatches the communications appropriately, filtering out undesired
commumications and converting communications
into a format that the recipient can make use of immediately. It does all this
while protecting the location privacy of the recipient from the message
sender and allowing the easy integration of new application protocols.
The IdentiScape project introduces a name service that allows
us to name people across all online applications in a unique, robust,
and historically persistent manner.
Mary Baker is an assistant professor in the Departments of Computer
Science and Electrical Engineering at Stanford University. Her interests
include operating systems, distributed systems, and mobile networking.
She is now leading the development of the MosquitoNet mobile
and wireless computing project and the Mobile People Architecture.
Baker received a BA degree in mathematics in 1984 from the University
of California at Berkeley, and MS and PhD degrees in computer science
in 1988 and 1994 also from U. C. Berkeley. Baker is a recipient of an
Alfred P. Sloan Research Fellowship, a Terman Fellowship, an NSF Faculty
Career Development Award, and an Okawa Foundation grant.
