NSF DEMO 1 DESCRIPTION ¶

INTRODUCTION ¶

The objective of this demo is to show the federation of the two heterogeneous testbeds: Planetlab and ORBIT. This demonstration illustrates a typical wireless hotspot scenario with one node in the ORBIT testbed fetching video media off a remote Planetlab node and serving it to a fixed and mobile client.

The demo has been choreographed to use nodes 17-2 and 17-7, where 17-2 is the hotspot AP that fetches the media content off a remote Planetlab node planetlab-1.cs.princeton.edu and serves it to node17-7 as well as the robot based mobile node.

Bitrate (in kbps) is measured by the receiving node and reported to the ORBIT infrastructure using the OML library.
