abstract = {Meshmerize is an opportunistic multi-path wireless mesh routing protocol
designed for dynamic networks. It ensures persistent connectivity to even
mobile nodes in the network. Classical mesh routing protocols fail
frequently when the nodes are mobile. In this demo, we demonstrate the
resilience of Meshmerize and the shortcomings of the classical protocols
using an emulated drone network. The audience can pilot a (virtual) drone
in a city through a meshed network of base stations and experience the
latency and reliability of both protocols first hand.},

abstract = {The digitalization of manufacturing processes is expected to lead to a growing interconnection of production sites, as well as machines, tools and work pieces. In the course of this development, new use-cases arise which have challenging requirements from a communication technology point of view. 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.},

The state-of-the-art wireless mesh networking protocols that provide
self-organizing networks like BATMAN and OLSR do not address the demands of
5G networks such as low latency and high reliability. 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.},

abstract = {This paper investigates the performance of wireless mesh networks
advocating for Opportunistic Routing (OpR) over traditional Single Path
Routing (SPR). 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.},
