Abstract

The introduction of mobile code in the pervasive computingenvironment provides a good opportunity for research inways to enhance execution flexibility. We note that currentmobile code is too heavyweight and not adaptive enough tobe used in pervasive computing where devices are resource-limitedand heterogeneity is the norm. In this paper, we proposea new lightweight, component-based mobile agent systemthat can adapt to diverse devices and features resourcesaving as one of its aims. The system supports strong mobilityof mobile code, which is a prerequisite for achieving systemflexibility and good performance. The system discretizethe transmission of code and execution states and relies on ascheme called state-on-demand (SOD) for the execution ofthe mobile code. We provide performance results to demonstratethe effectiveness of the SOD scheme.
