2. Where Is WSN? Technology Trigger Peak of Inflated Expectations Trough of Disallusionment Slope of Enlightenment Plateau of Productivity Visibility Time

3. Industrial Automation Usage Classes Safety Class 0 : Emergency action (always critical) Control Class 1: Closed loop regulatory control (often critical) Class 2: Closed loop supervisory control (usually non-critical) Class 3: Open loop control (human in the loop) Monitoring Class 4: Alerting Short-term operational consequence (e.g., event-based maintenance, asset tracking) Class 5: Logging & downloading/uploading No immediate operational consequence (e.g., history collection, SOE, preventive maintenance) Importance of message timeliness increases Source: ISA-SP100 User Goals, Tom Phinney, ISA Expo, 2005

4. Requirements Cost –Capital expense –Operational expense –Easy installation and maintenance –Power management Compatibility & Scalability –Interoperability/Shared infrastructure –Worldwide usability –Capacity and scalability Performance –Reliable communication –Adequate reporting rates Quality of Service (QoS) –Timeliness (latency) and successful throughput –Delivery ordering –Recovery action Security System Management Standard Compliance Source: ISA-SP100 User Goals, Tom Phinney, ISA Expo, 2005

9. Mela Networks WSN Software Enable users to rapidly and cost effectively deploy integrated, interoperable solutions for networked sensors across all device platforms, with centralized management and control Build on Open Source Tools and Spring Framework –Spring framework, modular, maximal code reuse, wired by config files –Deployable to any standard J2EE container/application server, Apache Tomcat, Websphere, Oracle App Server, WebLogic –Hibernate and Data Access Object, support any database, mySQL, PostgreSQL, Oracle DB, SQL Server –Java and JSP, “cross platform” –Model View Controller (MVC) pattern, separate presentation from business logic from data, easy customization –Web services (SOAP) to interface with Enterprise applications –Structured XML, translators for any WSN vendor XML interface –AJAX, optimizing user experience Plug and play with legacy industrial automation protocols, e.g. Modbus

10. Functionalities Command and Control dashboard with summary alarm status –Easily apply user-defined business rules for immediate visibility and notification of exceptions Network topology –Monitor network health and connectivity Data analysis and graphs –Easy and intuitive data access and trending Configuration of device profiles and server settings –Easily configure and control a network of devices graphically Web Services Interface –Transform raw data into actionable events and seamlessly integrate the events with existing enterprise execution systems.

22. Application Requirements 2 years battery life (1 sec sensor sampling rate & 10 sec/packet) High reliablity (> 99.9%) Automatically picks clean channels to avoid interference Edge node able to pick the best router to connect to the network Mesh backbone should have redundancy, be self-healing Fast reconnect time when parent down: ~ O (1) sec Ease of deployment: automatically pick clean channels, avoid interference Hot standby base node to prevent single point of failure Network provides sufficient health information, periodically & on-demand Customer can develop its own command and control applications to monitor the readings, configure devices through device profiles Customer can develop sensor drivers easily Separation of the network logic from the storage logic Future: battery powered routers with sensors attached to them.
