Resource Description Language: A Unified Description Language for Network Embedded Resources

摘要

As machine-to-machine networks become larger and more pervasive, manualconfiguration and discovery of resources will become intractable. It is in this context thatwe propose the RDL, a Resource Description Language that represents a uniform way ofdescribing embedded resources, allowing them to be shared and enabling a new class ofresource-aware applications. The RDL can describe a wide range of resources, characterizingindividual nodes or entire networks. It can contribute to overcome performance issues indense networks or mobility-driven problems in highly dynamic machine-to-machine topologiesby providing the means for self-adaptability and manageability, as well as opportunisticresource sharing in context-aware embedded applications. The main goal for the RDL isto define a reusable and extensible resource description specification, which can only bereached if the resources are described in a standardized format. To illustrate the feasibilityof our approach, we have also developed a Java implementation of the RDL framework,as well as a TinyOS implementation targeting resource constrained platforms. Furthermore,we have developed Modulus, a modular middleware for the development of resource-awaredistributed applications.
