Automatic Topology Estimation in Wireless Lamp Networks (L)

Status: Abgeschlossen

The goal of this lab project is to investigate automatic topology estimation in smart home environments. When deploying new appliances, recent solutions require a time-consuming manual configuration of every single device. A simple example is the placement of floor lamps in offices. Traditionally, the lamps are connected to a central controller that knows the topology of the lamps and allows for ambient light control. The purpose of this work is to find out whether automatic topology discovery is possible by measuring the received signal strength of neighboring devices. We will focus on an indoor scenario with fixed floor lamps equipped with ZigBee communication and IBM MoteRunner operating system.

Students have to design and implement a test setup to analyze whether the received signal strength value can be used to derive a relative topology or not. For this, create a wireless protocol which measures the RSSI value of nodes and exchanges this information with neighbors. Additionally, a method should be developed to collect RSSI values and analyze the data using statistical methods.

The project is in cooperation with IBM Research Rüschlikon.
