Abstract
Mobile computers using wireless networks, along with multimedia
applications, are two emerging trends in computer systems. This new
mobile multimedia computing environment presents many challenges, due
to the requirements of multimedia applications and the mobile nature
of hosts. We present several alternative schemes for maintaining
network connections used to provide multimedia service, as hosts move
through a nano-cellular radio network. These algorithms modify
existing connections by partially reestablishing them to perform
handoffs. Using a simple analytical model, we compare the schemes on
the basis of the service disruption caused by handoffs, required
buffering, and excess resources required to perform the handoffs.
