A decoder receives packets containing uncoded and coded symbols. When a packet with a coded symbol is received, the decoder determines whether a packet sequence number is within a sliding window of w consecutive sequence numbers that are no greater than a decoder sequence number, where the number w is fixed prior to encoding. When this is the case, the decoder decodes the coded symbol into one or more of the w input symbols using the coefficient vector. Decoding may use a forward error correcting (FEC) window within the finite sliding window. Decoding also may use a technique of Gaussian elimination to produce a "shifted" row echelon coefficient matrix.}, keywords = {}, pubstate = {published}, tppubtype = {patent} }

In this paper we propose a communication network architecture for Industry 4.0 applications, which combines new 5G and non-cellular wireless network technologies with existing (wired) fieldbus technologies on the shop floor. This architecture includes the possibility to use private and public mobile networks together with local networking technologies to achieve a flexible setup that addresses many different industrial use cases. It is embedded into the Industrial Internet Reference Architecture and the RAMI4.0 reference architecture. The paper shows how the advancements introduced around the new 5G mobile technology can fulfill a wide range of industry requirements and thus enable new Industry 4.0 applications. Since 5G standardization is still ongoing, the proposed architecture is in a first step mainly focusing on new advanced features in the core network, but will be developed further later.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

In this demonstration, we exhibit how we build a reliable low latency network out of a chaotic and dynamic wireless mesh network. We combine the principles of opportunistic routing and network coding to achieve this. We let the audience to interact with the nodes of the wireless mesh networks, i.e. causing node failures, link changes, etc. We demonstrate how our mesh network retains all of its flows intact without any service interruption despite these interactions and node failures.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

Cooperation Group Size in Opportunistic Wireless Mesh: Optimal Versus Practical Proceedings Article

In OpR, all nodes overhearing the transmission can form a cooperation group and forward the fragments of the received message. The bigger the cooperation group, the more is the message sub-divided and the harder it gets to manage this process. If poorly managed, multiple duplicate fragments can be forwarded that downgrades the overall performance and destabilizes the routing protocol. In this paper, we propose several methods for shrinking the cooperation group and define the best one that can be later used as a part of the routing protocol. Using a testbed of 15 node WiFi network deployed in the office building, we show that the cooperation group size can be significantly reduced using our proposed methods. The throughput gain of OpR over SPR reaches as high as 51% in our testbed. We also show that only 3% of the average gain is lost when shrinking the cooperation group to less than one-third of its original size. The conducted measurement and the analysis of the results form the benchmark for potential performance evaluation of the mesh networks.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }
