Traditional protocols rely on finding a routing path between sensors generating data and sinks acting as gateway or databases. Meanwhile, the network will suffer from high collisions in case of high data rates. In this context, in-network processing solutions are used to leverage the wireless nodes' computations, by distributing processing tasks on the nodes along the routing path. Although in-network processing solutions are very popular in wired networks (e.g., data centers and wide area networks), there are many challenges to adopt these solutions in wireless networks, due to the interference problem. In this paper, we solve the problem of routing and task distribution jointly using a greedy Virtual Network Embedding (VNE) algorithm, and consider power control as well. Through simulations, we compare the proposed algorithm to optimal solutions and show that it achieves good results in terms of delay. Moreover, we discuss its sub-optimality by driving tight lower bounds and loose upper bounds. We also compare our solution with another wireless VNE solution to show the trade-off between delay and symbol error rate."}],"user_id":"65718","department":[{"_id":"75"}],"project":[{"name":"Akustische Sensornetzwerke - Teilprojekt \"Verteilte akustische Signalverarbeitung über funkbasierte Sensornetzwerke","_id":"27"}],"_id":"12881","language":[{"iso":"eng"}]},{"title":"A Rapid Prototyping for Wireless Virtual Network Embedding using MARVELO","oa":"1","date_updated":"2022-01-06T06:51:22Z","author":[{"last_name":"Afifi","id":"65718","full_name":"Afifi, Haitham","first_name":"Haitham"},{"first_name":"Holger","id":"126","full_name":"Karl, Holger","last_name":"Karl"},{"last_name":"Eikenberg","full_name":"Eikenberg, Sebastian","first_name":"Sebastian"},{"first_name":"Arnold","full_name":"Mueller, Arnold","last_name":"Mueller"},{"first_name":"Lars","last_name":"Gansel","full_name":"Gansel, Lars"},{"first_name":"Alexander","last_name":"Makejkin","full_name":"Makejkin, Alexander"},{"last_name":"Hannemann","full_name":"Hannemann, Kai","first_name":"Kai"},{"full_name":"Schellenberg, Rafael","last_name":"Schellenberg","first_name":"Rafael"}],"date_created":"2019-07-24T07:28:45Z","year":"2019","place":"Marrakech, Morocco","citation":{"ieee":"H.

There is substantial interest in being able to verify such proofs and also in using them for further computations. In this paper, we present an FPGA accelerator for checking resolution proofs, a popular proof format. Our accelerator exploits parallelism at the low level by implementing the basic resolution step in hardware, and at the high level by instantiating a number of parallel modules for proof checking. Since proof checking involves highly irregular memory accesses, we employ Hybrid Memory Cube technology for accelerator memory. The results show that while the accelerator is scalable and achieves speedups for all benchmark proofs, performance improvements are currently limited by the overhead of transitioning the proof into the accelerator memory."}],"status":"public","publication":"Journal of Signal Processing Systems","type":"journal_article"},{"type":"dissertation","status":"public","file":[{"date_updated":"2020-01-16T12:09:52Z","date_created":"2020-01-16T12:09:52Z","creator":"florida","file_size":1740910,"access_level":"closed","file_name":"Dissertation_Stefan_Heindorf.pdf","file_id":"15603","content_type":"application/pdf","success":1,"relation":"main_file"}],"department":[{"_id":"66"}],"user_id":"477","_id":"15333","project":[{"name":"SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C5","_id":"17"}],"file_date_updated":"2020-01-16T12:09:52Z","language":[{"iso":"eng"}],"ddc":["040"],"has_accepted_license":"1","citation":{"ieee":"S.

To structure the included studies, I use a stakeholder approach and outline how corporate income taxation plays into the relation of banks and their four main stakeholders: bank regulators, customers, investors and tax authorities. My contribution to the literature is threefold: First, I contribute by providing, to the best of my knowledge, a first comprehensive review on this topic. Second, I point to areas for future research. Third, I deduce policy implications from the studies under review. In sum, the studies show that taxes distort banks’ pricing decisions, the relative attractiveness of debt and equity financing, the decision to report on or off the balance sheet and banks’ investment allocations. Empirical insights on how tax rules affect banks’ decision-making are helpful for policymakers to tailor suitable and sustainable tax legislation directed at banks.
