The prestigious awards for the best PhD thesis was awarded by the society "Verein der Freunde und Förderer der ComNets-Einrichtungen" in Aachen at 03.13.2015. This society is researching on future communication networks. The Bernhard-Walke-Award, which is endowed with 1500 Euro, was given to Dr.-Ing. Björn Dusza, for his PhD Thesis with the Title "Context-Aware Battery Lifetime Modeling for Next Generation Wireless Networks". He was working on that subject as an employee at the chair for communication networks (Prof. Dr.-Ing. C. Wietfeld) at the TU Dortmund. The thesis was a contribution to the collaborative research centre 876 "Providing Information by Resource-Constrained Data Analysis". An analysis and stochastic models were used, to research on the power consumption from LTE communication processes from end devices. The results from this thesis makes it possible for the first time, that a network operators could measure the influence from design and assigning network ressources on the battery running time. The collaborative research centre 876 uses the results to decide whether it is better that the data from a sensor is localy analyzed or transfered to some infrastructure.
