Emerging mobile and ubiquitous computing environments present hard challenges to software engineering. The use of mobile code has been suggested as a natural fit for simpli-fying software development for these environments. Exist-ing strategies for locating mobile code assume an underly-ing fixed, stable network. An alternative approach is required for mobile environments, where network size and reliability cannot be guaranteed. This paper introduces AMOS, a mo-bile code platform augmented with a structured overlay net-work. We demonstrate how the location discovery strategy of AMOS has better reliability and scalability properties than existing approaches, with minimal communication overhead. Finally, we show how AMOS can provide autonomous distri-bution of effort fairly throughout a network using probabilis-tic methods that requires no global knowledge of host capa-bilities.
