Implementation and Evaluation of a Mobile PlanetLab Node

With the introduction of cellular phones, mobile wireless communication has become an integral part of day-to-day life in this century. A testbed is crucial in continuing cutting- edge wireless technology research and development since physical and MAC layers in mobile wireless communica- tion have many parameters pertinent to performance that are often not tractable in analysis or simulation alone. Although many wireless testbeds have been built, most are not gen- eral purpose, have a limited access policy, or focus on single technologies like WiFi. In this paper, we present the im- plementation and evaluation of a mobile testbed node. This node will be the founding block of a mobile wireless testbed that we envision to be as open as PlanetLab to researchers.
