BA: Power Sharing Networks – Simulation Tools for Power Sharing in Body Area Networks

Friday, 11. November 2016

Body Area Networks (BAN) are a specialization of the Sensor-Network Paradigm. A set of usually wirelessly communicating devices (e.g. sensors, actors, smart devices, wearables) is attached to the user’s body. Besides common application domains like interconnected medical devices, BANs nowadays arise from the trend towards using multiple device simultaneously (e.g. smart phone, smart watch, glasses, sensors embedded in clothes). A critical resource with networks of mobile devices is power/energy. While some devices contained in the BAN may quickly run out of power due to frequent usage, others may possess remaining capacity. Therefore, researches are currently investigating the possibilities to not only share data, but also power in networks of mobile devices. Different approaches including wireless and wired power transmission exist. Even though a significant amount of power is expected to be lost due to transmission, power sharing can improve the usability and user experience of commodity BANs. While the efficiency is subject to ongoing research, the approach in general is further motivated by the existence of energy harvesting devices in the BAN that can act as power sources (e.g. a kinetic energy harvesting shoe).

The objective of this bachelor thesis is to extend and advance a simulation tool for power sharing in BANs. This tool will help to further promote the early stage research on algorithms and protocols that are required to make informed decisions in power sharing networks. Moreover, it will help designers of power sharing technologies to assess whether and how certain setups can be implemented or improved. 

Students interested in the topic should have profound knowledge of Java programming. The topic is available in German and English language.
