Seminar Connected and Mobile Systems (Master)

Give an overview of current routing protocols and their suitability for ultra low power environments. Your focus should be lying on energy harvesting systems, where nodes are not always powered. Your research should also include scheduling algorithms, because this is required for routing protocols. Finally, make a comparison of the protocols and try to find the mostsuitable one.

With the increasing amount of functionalities in modern vehicles a considerable amount of wires are needed to connect systems and sensors. Wireless technologies with ever increasing performance in throughput, latency and reliability offer great opposites, as wired connections could be replaced to reduce the weight and complexity of the cable harness in vehicles. The task for the seminar is to describe, compare and evaluate existing approaches and outline the state of the art in wireless Intra-Vehicular Networks with a focus on the technologies used and their performance.

• Bluetooth Low Energy based Communication Framework for Intra Vehicle Wireless Sensor Networks
• Hybrid Wireless Harness for Low Mass Vehicular Applications

Distribution of sensor information in VANETs is crucial for cooperation between vehicles. When performing driving actions vehicles depend on this information and thus, safety is of concern. Several misbehavior detection schemes have been proposed to detect and coop with false and/or malicious sensor data. The task of your research is to identify, summarize and differentiate different detection techniques.

• Machine Learning Approach for Multiple Misbehavior Detection in VANET
• A Detailed Survey on Misbehavior Node Detection Techniques in Vehicular Ad Hoc Networks

Quite a few systems use phase information of a signal to determine distance between devices. However, the type of signal might differ heavily (sound, light, radio). The task of your research is to give an overview of the differences and similarities of these systems. What are the algorithms to determine the distance from the phase? Are they similar? Could they be applied to other types of signals as well?

• Accurate and Precise Distance Estimation from Phase-Based Ranging Data
• Robust Chinese Remainder Theorem Ranging Method Based on Dual-Frequency Measurements
• Phase based spatial identification of UHF RFID tags
