When generating Collective Perception Messages (CPMs) it is important to keep a look on the channel load caused by their transmission. Therefore after applying some general filtering using generation rules [0], there are some recent works proposing to further reduce the number of shared objects by applying so called Redundancy Mitigation Techniques. They are summarized in the current draft of the CP Standard [1]. However, reducing the redundancy also has some downsides because it limits the abilities of Misbehaviour Detection (MBD) approaches leveraging the fact that information about one particular object is available from multiple sources and can therefore be validated by, e.g., a majority voting.


Your tasks in this theses are as following:

  • Implement currently existing redundancy mitigation techniques (might already be done by the time the thesis starts)
  • Evaluate their effectiveness in terms of channel load reduction
  • Implement and evaluate a redundancy based MBD scheme like [2]
  • Re-evaluate the MBD scheme with active Redundancy mitigation schemes
  • Propose a trade-off


All the evaluations will be done in simulation using the Artery V2X Simulation Framework [3], using the existing implementation of the CPS [4]. In order to complete the task, the student needs basic skills in C++ and knowledge about vehicular networks. However, it is also possible to acquire those skills along the way.
