Type of work: Bachelor thesis

Technical background:

In Rostock there are several LoRaWAN Radio Gateways where we have access to the encrypted transmitted messages. The university itself operates a number of mobile nodes (mainly sensors). In addition, the radio gateways are used by a large number of unknown mobile nodes to send data via network servers to application servers. In this specific case, the Radio Gateways are registered with The Things Network.
 

Task Description:

We would like to determine some statistical information about the usage of the Radio Gateways. Questions include:

• How much use is made of each gateway in the city area over time?
• How many different nodes are involved?
• How mobile are the nodes?
• How are a station's transmissions distributed over time?

Possible work steps:

• Familiarisation with background LoRaWAN and the components of the network.
• Data acquisition
• Implementation of an interface and
• Collection of data in a suitable database
• Data mining / data warehousing
• Evaluation and presentation of the results

The exact definition of the topic is done in consultation with the supervisor, taking into account any topics already assigned to other students. Joint processing of different sub-topics by several students is possible under certain circumstances.
