Development of software architecture for environmental monitoring using wireless sensor networks

摘要

In this thesis, I describe the development of the software architecture for temperature monitoring using Wireless Sensor Networks (WSN). The goal of the software is to provide a means to remotely monitor and analyze temperature data in a closed environment. This architecture forms a building block to achieve the larger aim of energy management in built facilities. A 16 node wireless sensor network was set up to monitor ambient temperature at various locations in MIT. A console application was developed in the C# language to collect temporal sensor data and store it in a SQL database. The application also provides a management system for fire hazard warnings by sending e-mails and calling mobile phones. An ASP.NET web application is then developed to retrieve temperature data over Internet. The data is accessible in different formats-table, XML and visualized in graphical form. This application lets the user register their phone numbers and e-mails to be informed in case of a fire emergency or excessive heating/cooling. A mobile application is developed on top of the web application to increase the range of data access to handheld Internet enabled telephony devices such as mobile phones and PDAs.
