## 6 Conclusions  
We presented the WSN-DPCM integrated toolset for WSN application planning, development, commissioning and maintenance, which has been specified, designed and implemented within a UE ARTEMIS-JU project. The toolset aids and assists the application-domain experts, may have limited WSN expertise, in the task of efficiently developing WSN applications from planning to lifetime maintenance. The main benefits of the WSN-DPCM toolset at platform level are:  
* Reduction of trial-and-error WSN deployments, thanks to the extensive multi-level simulation support (RF simulation, network simulation). * MDA-based automatic system synthesis and code generation, through reusability of software and hardware components from extensible libraries. * Simplification of the design, deployment and maintenance phases of real-life deployments by using a software-assisted approach. * Middleware support for abstraction from the complexity of WSN environments composed of a multitude of embedded platform technologies.

The benefits of the proposed toolset have been evaluated using two case-studies in two different WSN application domains: one that detects the occupancy state of parking places and one that detects the presence of concentration of potentially harmful agents in the atmosphere. These applications have been chosen to exercise the toolset for the design of typical WSN application elements, such as different network topologies (cooperative short-range mesh networking for parking and star-based long-range for air quality), for design space exploration to instrument the nodes with the proper types of sensors and optimize their operation, and for optimal field deployment simulation and in-field support. The importance of node and network optimization, remote monitoring and troubleshooting is also different. The network in the parking deployment has a more complex structure but the cost of service is lower, while the network for the air quality application is simpler, but the reliability of the nodes and the network is more important because they are more costly to service during exploitation. The toolset integrates in a unified framework several of the existing state of the art tools together with new productivity-enhancing tools developed during the project. The resulting framework supports well typical WSN development flows and is accessible to most application domain experts. The toolset allows the developer to efficiently focus on the application-specific elements by automating much of the time-consuming details that are not directly relevant for the application. Moreover, the modular structure of the framework and of the main composing tools simplify its maintenance and extension with new tools and IPs, either proprietary or open, for its continuous evolution and customization for specific needs. Last but not least, the proposed framework is built around the concept of complete, end-to-end WSN application project, which simplifies the passage of data between the tools that support the various design phases, iterative exploration of different design variants and their comparison, as well as comparison and optimization of field results with respect to design specification and simulations.
