Build an indoor sensor network

Introduction

As sensor networks becomes more common, our homes and workplaces can be monitored. A combination of WSNs and actuator networks can create what is sometimes referred to as smart homes. WSN might help automate our homes to improve, for example, energy consumption by adapting lighting and heating when an area is used. Problems that need to be solved include how to sense the environment and react to events but also how to configure such a system.

Task

Deploy a mote network in one corridor in Ångström and provide an interface to the system. The mote network consists of telosb/tmotesky sensor nodes that are connected to a wired control channel. The control channel allows us to program and control the sensor nodes remotely. The sensor nodes have sensors to collect data about light, temperature and humidity but other sensors can be attached. Sensor node software to collect sensor data and communicate it needs to be written either in Contiki (http://www.sics.se/contiki/) or TinyOS (http://www.tinyos.net/). To react to sensor events, a tellstick (http://developer.telldus.se/) will be connected to the control network. The tellstick can control individual wall outlets, for example turning light on and of.
