Asset tracking systems developed around the Internet of Things paradigm are composed of a collection of various objects interconnected by different communication technologies. Each of these devices function through local and/or remote interaction with the real world or other devices and systems. The problem of ensuring a dependable and responsive middleware that is capable of handling and servicing such devices, process voluminous data without compromising responsiveness is still eminent. In this paper, we present a solution that was designed using in-lining approach to deliver a middleware that acts as an insulator for hiding the internal workings of the asset tracking system prototype by providing homogenous and abstract environment to the highest layers. In order to evaluate the middleware, a laptop tracking and monitoring system that integrates various internet of things components (at least 4 components: RFIDs, wireless sensors, mobile phones and biometric readers) was implemented and tested within a university environment.
