Device Middleware for Heterogeneous Access to Java Services

The mobile phone environment is today highly concerned about security threats of buggy, malicious or viruses´ code that an end user could download and crash the phone. To prevent this, mobile phones applications operates a virtual sandbox that runs each application in a tightly constrained environment separated from each other. This work proposes a device middleware, namely D-Mid, which leverages an existent device framework to provide an agonistic application model that supports heterogeneous access to the middleware with a minimal impact on performance. Besides mobile devices are likely to have scarce resources, such as memory and CPU clock, so D-Mid provides an inversion of control mechanism that targets a minimal execution environment.
