Metrics for Performance Evaluation of Distributed Application Execution in Ubiquitous Computing Environments 1
Prithwish Basu, Ke Wu · 2001
With the rapid growth in tetherless portable computing and wireless networking technology, ``Ubiquitous Computing'' is coming of age. Corporate offices, college campuses, as well as hi-tech homes are embracing such technologies gradually. Specifically, wireless LAN support, which is one of the first concrete steps towards achieving ubiquity in computing has been growing at a fast pace, recently. A case in point is the Carnegie Mellon University campus where there are 400 wireless network access points enabling coverage for the entire campus, indoors and outdoors. As computing becomes truly ubiquitous, more resources are available to perform common user tasks (as well as more esoteric ones). This implies that in such environments, there are more choices of resources for performing these tasks. In this position paper, we describe specific metrics as well as system parameters that are necessary for quantifying success of dynamic execution of entire user applications or tasks in ubiquitous computing environments where different services are offered by several categories of devices.
