Secure Index on Distributed Data: UML Extension for Wireless Sensor Networks

The research on wireless sensor network has evolved with applications being developed in several domains. However, applications designed for wireless sensor network are attributed with programming which occurs at lower levels of abstractions of the operating system. The application designer has to be aware of both the domain of the application and its corresponding hardware platform. This creates a strong coupling between the implemented code and hardware platform. Hence all applications are designed for specific platforms and become difficult to maintain, modify and reuse. Our proposal creates UML models for a WSN application to formalize it according to a development life cycle. Secure Index on Distributed data (SIDD) is an application that addresses two issues of data distribution and security. The UML model helps to harmonize the domains of security and application. Hence the paper focusses on converging the designing process into a formal development mode using UML representations.
