Framework of an application-aware adaptation scheme for disconnected operations

Abstract

The complex software development scenarios for mobile/hand-held devices operating in wireless environments require adaptation to the variations in the environment (such as fluctuating bandwidth). This translates to maintenance of service availability in preferably all circumstances. In this paper we propose that a mobile computing system (for hand-held, wireless devices) must be based on the combination of reflection, remote evaluation and code mobility mechanisms such that the communication framework1 allows developers to design disconnection aware applications which maintain service availability in case of varying circumstances by automatically redeploying essential components to appropriate locations. This not only allows the application to continue executing in varying conditions, but also in entirely disconnected modes. ©IFIP International Federation for Information Processing 2009.
