  1. Sens4U: Wireless Sensor Network Applications for Environment Monitoring Made Easy Krzysztof Piotrowski and Steffen Peter

  2. Agenda • Background • Use case • Extended module concept • Applicationlogicdefinition • Ideal configuration • Conclusions

  3. Scenario 1: Monitoring Beaver Behavior

  4. Scenario 2: Opencast mine

  5. Background • TwocomplementaryPhDtheses • ConfigKit – automaticcreationofmodule-based WSN softwareconfigurationsbased on securityrequirements • tinyDSM – configurabledatastoragefor WSNs witheventdetectionand user-defineddataitems, replicationandconsistency • Combinationofthesesupportsacceleratedapplicationdevelopment • Extensions in bothareasneeded • Extension oftheConfigKitconcepttosoftwareandhardwareandarbitrary (not securityonly) setofrequirements • Simplificationofmethodsallowingthedescriptionofapplicationlogicthatbecomesthe top-level softwaremodule • Environment monitoringapplicationsastheareaofthe Sens4U project

  6. Usecase • Customer defines her requirements: • Locations, Measurements, Maintenance, Reliability • The integrator inputs these into the Planning tool • The Expert System combineschosenmodulesaccordingtotherequirements • The Verificationprocessmaytrigger additional loop, e.g., updatingthemodulepooloradjustingtherequirements • The chosenconfigurationisimplemented • Wefocus on environmentmonitoringscenarious

  8. Roles in the development process • End user • Application designer • Integrator User Module Pool ComponentDeveloper FrameworkDesigner

  9. Module Pool relations • includesdefinesthat a modulebelongsto a larger module, e.g., a µC belongsto a nodeplatform. • usesdefinestheinterfacesusedby a givenmodule • providesdefinesinterfacesprovidedby a givenmodule • has_parameterdefinesthevalueof a parameterfrom a providedinterfaceforthegivenmodule • requires_parameterdefinestherequiredvalue(s) of a parameterfrom an usedinterfaceforthegivenmodule

  10. Applicationlogicdefinition • Transformation ofthe non-technicalrequirementsinto a setoftechnicalrequirements • The mosttrickypartofthesystem

  11. Requirements • Requirements are: • Technical parameters and constraints • Description of environment • Description of participants (user, attacker) in the scenario • User requirements are often fuzzy and non-technical • Need for translation of user requirements to technical requirements • User selects and parameterizes properties from a requirement catalogue • They will be translated to technical requirements • Example: Requirements User Requirements Technical Requirements • - Application type (health care, home, industrial) • Required security attributes (concealment, integrity, robustness) • Parameters Attacker model and capabilities

  12. Applicationlogicdefinition, cont • Possible on different detail/experiencelevels • Macroprogramming • Scripting • Pure moduleprogramming • Weidentifiedthemostcommonpatterns (requirementscatalogue) • Withthefocus on environmentmonitoring • Weprovide a GUI todefinetheapplicationlogic (Planning Tool) by: • Providing thegroundviewforthemonitoredarea • Definingcommunicationenvironmentandobstacles • Definingthemeasuringpoints,proceduresanddatadependencies • Prototype implementation will beavailablesoon

  13. Methodology Find models to express properties as function between requirements and system Requirements components • Does the system under development satisfies the requirements? Models Component and system model • How to define requirements? • understood by users • Precise for the system SYSTEM Formal framework

  17. Conclusions Wepropose a systemthat: • supports the non-WSN-experts in the specification of they real-life target system requirements, • provides a module description framework to support computer aided application development and module testing, • allows creating application specific/optimized software and hardware configurations, • does not only suggest software compositions, but also suggests hardware components with diverse granularity (platform, chip, module) and functionality (accelerators, sensors, actuators) to fulfill the given task, • utilizes an user and process model that emphasizes the applicability by non-WSN-experts.
