Overview:

In pervasive computing environments, conditions are highly variable and resources are limited. In order to meet the needs of applications, systems must adapt dynamically to changing situations. Since adaptation at one system layer may be insufficient, cross-layer, or vertical approaches to adaptation may be needed. Moreover, adaptation in distributed systems often requires horizontal cooperation among hosts. This paper presents the KMX architecture and discusses its potential role in supporting universal adaptation in pervasive computing environments. They then describe a prototype implementation of KMX and show results of an experimental case study in which KMX is used to improve the quality of video streaming to mobile nodes in a hybrid wired-wireless network.
