Service Component Architecture Extension for Sensor Networks

The role of small electronic devices has been growing over the past years. Many types of devices which allow for interaction with the environment can now be found in the market and there is large set of solutions for integration of mobile devices with enterprise systems. However, most such solutions focus only on providing base services for other SOA system elements. The paper presents an extension of the SCA programming model to include intelligent sensors and a concept of uniform programming model shared between sensor networks and standard computers. The architecture of such an extension is proposed and an initial prototype implementation is presented. The solution utilizes a proxy pattern, validated by a simple case study using Sun SPOTs and Sentilla. The advantages and limitations of the proposed extension are also discussed.
