Abstract
This Chapter presents the Programming and Execution Module (PEM) of SmartSensor. The main purpose of PEM is to allow end users to program Web mashup applications through the composition of a mixing of public available services and services provided by SmartSensor registered in SIMs. Web mashups are ad-hoc Web applications built upon the combination of real-time information (data, presentation and functionality) from multiple Web sources. The PEM’s programming environment provides a Web Mashup DSL (Domain Specific Language) specifically tailored for the WSN environment, as well as an interpreter for such DSL. Moreover, this module contains components for publishing and discovering the capacities of available WSNs. PEM’s DSL is an extension of the Enterprise Mashup Markup Language (EMML), which is an open language specification, promoted by the Open Mashup Alliance. The main goals of EMML are to provide programming mechanisms to promote mashup design portability and interoperability of mashup solutions aiming at reducing vendor lock-in.
