Bachelor-Seminar Connected and Mobile Systems

"Security comes last" is a common saying in Computer Science, but which attacks exists and how can systems be secured? In the context of Wireless Sensor Networks (WSNs), your task is to find possible weak points, known attacks and security concepts and to present them.

• Assessment of Routing Attacks and Mitigation Techniques with RPL Control Messages: A Survey
• An Efficient Multilevel Probabilistic Model for Abnormal Traffic Detection in Wireless Sensor Networks
• WSN-SLAP: Secure and Lightweight Mutual Authentication Protocol for Wireless Sensor Networks
• Intrusion detection systems for RPL security: A comparative analysis
• Multicast DIS attack mitigation in RPL-based IoT-LLNs
• DETONAR: Detection of Routing Attacks in RPL-Based IoT
• Security Considerations for IEEE 802.15.4 Networks

Wireless Sensor Networks (WSNs) are deployed in various use-cases such as farming, wildlife management, and search and rescue operations. In cases, in which the WSNs are deployed in remote areas, energy efficiency is crucial since replacing the sensor's batteries at remote locations is expensive or, in some instances, even impossible. Recently, Unmanned Aerial Vehicles (UAVs), such as drones, have been used to assist in collecting the data produced by WSNs, creating a so-called UAV-Aided WSN (UAWSN). UAVs are leveraged as an easy to reach sink allowing the data to be transmitted either in fewer hops or are even needed to provide an uplink in general, e.g. in areas where no other uplinks like GSM are available.

Your task consists of two steps. In the first step, you will give a broad overview of UAWSNs and the routing algorithms designed for them. In the second step, you will pick two or three routing algorithms for detailed analysis and comparison.

• Overview of different routing algorithms for UAWSNs
• Wireless Communications with Unmanned Aerial Vehicles: Opportunities and Challenges

Collective Perception is a concept where vehicles exchange information about objects they detect with their local sensors. This way, vehicles can often know about the existence of objects long before they can detect them with their own sensors. One of the challenges with Collective Perception is when to transmit which part of the available data in order not to overload the communication channel. Since the publication of a Technical Report by ETSI, some new concepts have been proposed.

Your task is to first give an introduction to Collective Perception itself. Afterwards, research different message generation concepts and compare them to each other.
