Code Migration in Mobile Clouds with the NAM4J Middleware

Mobile Cloud Computing (MCC) is a model for transparent elastic augmentation of mobile device capabilities via ubiquitous wireless access to cloud storage and computing resources. The main purpose of MCC is to exploit the context-aware dynamic offload of demanding mobile applications to the Cloud, in order to improve their performance while saving energy and extending battery lifetime of devices. In this paper we extend a pre-existing MCC taxonomy, and we illustrate how the autonomic approach enabled by the open source NAM4J middleware with code migration support can effectively address MCC requirements. We recall the architecture of NAM4J and show its capabilities in the context of an Ambient Intelligence (AmI) MCC application for the Android platform.
