Selection of a topic
We offer the following topics for this course. You have to choose 3 topics currently not assigned to anyone (N.N.) and send your short list to firstname.lastname@example.org. Place the topic you are most interested in at position one etc.We will assign you to a topic - if possible - according to your preferences. In case of a collision and your list is exhausted the date/time of your registration determines the order (FCFS). We will tell you the topic or the failure of the assignment.
Topic: Autonomous Wildlife Monitoring: Software & Hardware Aspects (2 students)
State-of-the-art solutions to monitor and track animals in a scientific use case should be presented and evaluated. Pros and Cons of stationary vs. mobile Sensor Networks are the main aspects of this talk and should provide a detailed view of Hardware & Algorithms.
This topic is two-fold and ideal for two students as presentation length will be twice of the normal time. It is mandatory that both students work together, one will have a detailed look into the hardware and the other one into the algorithmic aspects (e.g. localization).

Topic: Cache-Control in the Web
Caching may help to accelerate content delivery. In this work, you should analyze current measurement papers that study caching behaviour in the World Wide Web. In particular, we are interested in common configuration of the Cache-Control field within the HTTP header. These insights allow us to better understand the design of future Internet approaches such as Information-Centric Networking.

Topic: Platform for internet of things
Give a survey about the main operating systems for the internet of things and used platforms. Set focus on classification of hardware platforms and/or usage model defined by organisations or hardware/platform vendors.

Topic: Collaborative Localization in Wireless Sensor Networks (WSN)
Localization in WSNs usually uses at least three sensors with accurate localization information (called anchors) to determine the position of a sensor (called node) within the network by applying a trilateration algorithm. This works as long as the node has a direct connection to each anchor - an assumption which does not hold for networks with a low density.
The idea behind collaborative localization is to use nodes that successfully determined their position as anchors for their neighbors which do not have access to a necessary amount of anchors.
While this is quite trivial in theory and has been a topic in the WSN community since a significant amount of time, there are only very few experimental evaluations yet. Your task is to search for publications which present real world experiments of collaborative localization algorithms. You should classify these publications and as a result present the state of the art in this field.

Topic: Authority-to-Citizen Aleart (atoca)
There seems to be variety of mechanisms that authorities have available to notify citizens and visitors during emergency events. Traditionally, they have done so with broadcast networks (radio and television). For commercial mobile devices, broadcasting services such as the Public Warning System (PWS), the Earthquake and Tsunami Warning System (ETWS), and the Commercial Mobile Alert System (CMAS) are standardized and are in various stages of deployment. In Germany the PPP project KATWARN is currently being rolled-out. The Internet provides another way for authority-to-citizen alerts to be sent, but it also presents new challenges. Briefly describe the key findings of the IETF working group atoca and point out the key challenges. Starting point: http://datatracker.ietf.org/wg/atoca/

Topic: Updating multi-hop Networks
Wireless Sensor Networks are optimized to transmit only few data, caused by high cost of energy per bit. Corresponding transceiver are optimized for idle time. What happens in the use-case of distributing new firmware within the network? In networks larger ten sensor nodes spread in a small area a 'wired' updating is an exhausting process. Present current approaches and optimizations for over-the-air updates in Wireless Sensor Networks.
