Proximity Services in highly Mobile Environments


There is a trend to enrich our environment with a multitude of sensors to enable new services based on sensor data. In this context, we have lamppost, which is equipped with different sensors to detect temperature, light intensity, pressure, humidity and infrared. One of the uses cases is black ice recognition.


The master thesis is in the field of Vehicle-to-Everything Communication (V2X Communication). The lamppost provides wireless access to nearby entities, which are in reach of the antenna. Therefore, the lamppost act as a gateway to provide different proximity services, such as a messaging system. The The service discovery must be fast due to time and distance restriction to ensure sufficient bandwidth for data transmission within connection time. It is important that the system works securely and addresses different threats. The use case considers a messaging system with different messages types for data payload and information sensitivity. For localization service encryption, no encryption and for warnings and information the system uses encryption. The goal is to inform nearby car drivers about road conditions (e.g., black ice), car accidents, blocked streets or free parking spots.

Goals and Objectives

  • Two entities implemented as virtualized Docker container (in Java or Python)
    • Lamppost that serves as service gateway
    • Car which uses the service
  • Experiments
    •  ONE simulator for networking
    • SUMO simulator for traffic conditions
    • Evaluation parameters
      • Service discovery and network association time
      • Amount of transferred data
      • Service delay due to lamppost hopping
      • Impact of weather conditions like rain modeled as additional delay in wireless communication



  • WiFi authentication fast enough for proximity services in high mobility environments?
  • How much data can be transferred during connection to lamppost?
  • Simulate with different bandwidth and driving speed
  • How can we model the smooth transition from one lamppost to another, if the coverage is lost to one lamppost during the drive

Optional: Security

  • What is the impact of security in this scenario under the aspect of real-time processing  
    • Performance impact: latency, throughput
    • System impact: implementation complexity
