@misc{51269, abstract = {{Free networks are established and maintained by more and more people on a voluntary basis to be independent from commercial providers. This also enables an uncensored communication and leads to a network owned by a community. Freifunk is such a project and it is based on wireless mesh networks. All participants provide an own wifi router (node) for transferring data between different devices. The routing protocol used in the Freifunk network of Paderborn is called Better Approach To Mobile Ad-hoc Networking advanced (B.A.T.M.A.N. IV or Batman-adv). It uses so called Originator Messages (OGM) to announce the existence of a node and to measure the quality of different links in the network. The Freifunk network in Paderborn consists of about 800 nodes that periodically broadcast OGMs. This leads to a substantial base load of ∼25 GByte per month and node. Instead of performing modifications in the real network, I create a simulation model of the current network structure and implement version IV of the B.A.T.M.A.N. routing protocol. The model is validated by using data from the real network. Based on this model I propose and evaluate five different opportunities to improve the base load without impairing other functionality of the network. The simulation results show that a combination of two improvements can lead to a reduction up to 90 %.}}, author = {{Hardes, Tobias}}, title = {{{Performance Analysis and Simulation of a Freifunk Mesh Network in Paderborn using B.A.T.M.A.N Advanced}}}, year = {{2015}}, } @inbook{27393, author = {{Bigga, Regine}}, booktitle = {{Allgemeinbildung und Curriculumentwicklung.

In this work we propose a procedure for selection of appropriate internal nodes in combinational clouds between pipeline stages or combinational parts of a sequential circuit to place hardware monitors that can effectively provide aging information of various components of a modern digital system. In order to implement the node selection procedure, we propose an object-oriented model. Object-oriented model of a circuit along with a probabilistic and logical simulation engine that we have developed can effectively be used for implementation and also fast evaluation of the proposed node selection mechanism. The proposed object-oriented C+ + models can be integrated into a SystemC RTL model making it possible to perform mixed-level simulation, and integrated evaluation of a complete system. We have applied our proposed scheme to several processors including MIPS, ARM, ALPHA and MiniRISC and have looked at its effectiveness for these processors.}}, author = {{Sadeghi-Kohan, Somayeh and Kamran, Arezoo and Forooghifar, Farnaz and Navabi, Zainalabedin}}, booktitle = {{2015 10th International Conference on Design & Technology of Integrated Systems in Nanoscale Era (DTIS)}}, publisher = {{IEEE}}, title = {{{Aging in digital circuits and age monitoring: Object-oriented modeling and evaluation}}}, doi = {{10.1109/dtis.2015.7127373}}, year = {{2015}}, } @inproceedings{46908, author = {{Koester, Dirk and Schütz, Christoph and Güldenpenning, Iris and Schack, Thomas}}, booktitle = {{Moving Minds - Crossing Boundaries in Sport Science.
