Software on wearable computers must adapt to dynamicenvironmental conditions, such as changes in packet lossbehavior on wireless communication channels. This paperinvestigates the use of programming language constructs torealize adaptive behavior. A prototype language, AdaptiveJava, was used to construct MetaSocket components, whosecomposition and behavior can be adapted to changing conditionsduring execution. MetaSockets were then integratedinto Pavilion, a web-based collaboration framework, andexperiments were conducted on a mobile computing testbedcontaining Xybernaut MA-V wearable computer systems.Performance results demonstrate the utility of MetaSocketsin reducing file transfer time and enhancing the quality ofinteractive audio streams.
