Florian Kauer und Volker Turau. Constructing Customized Multi-Hop Topologies in Dense Wireless Network Testbeds. In Ad-hoc, Mobile, and Wireless Networks, September 2018, pp. 319–331. Saint Malo, France.
@InProceedings{Telematik_adhocnow_2018, author = {Florian Kauer and Volker Turau}, title = {Constructing Customized Multi-Hop Topologies in Dense Wireless Network Testbeds}, booktitle = {Ad-hoc, Mobile, and Wireless Networks}, pages = {319-331}, day = {5-7}, month = sep, year = 2018, location = {Saint Malo, France}, }
Abstract: Testbeds are a key element in the evaluation of wireless multi-hop networks. In order to relieve researchers from the hassle of deploying their own testbeds, remotely controllable testbeds, such as the FIT/IoT-LAB, are built. However, while the IoT-LAB has a high number of nodes deployed in constraint areas. This, together with the complex nature of radio propagation, makes an ad-hoc construction of multi-hop topologies with higher number of hops difficult. This work presents a strategic approach to solve this problem and proposes algorithms to generate topologies with desired properties. The implementation is provided as open-source software. The algorithms are evaluated for the IoT-LAB testbeds. The results show that preset topologies of various types can be built even in dense wireless testbeds.

Abstract: Wireless mesh networks are a promising technology for connecting sensors and actuators with high flexibility and low investment costs. In industrial applications, however, reliability is essential. Therefore, two time-slotted medium access methods, DSME and TSCH, were added to the IEEE 802.15.4 standard. They allow collision-free communication in multi-hop networks and provide channel hopping for mitigating external interferences. The slot schedule used in these networks is of high importance for the network performance. This paper supports the development of efficient schedules by providing an analytical model for the assessment of such schedules, focused on TSCH. A Markov chain model for the finite queue on every node is introduced that takes the slot distribution into account. The models of all nodes are interconnected to calculate network metrics such as packet delivery ratio, end-to-end delay, and throughput. An evaluation compares the model with a simulation of the Orchestra schedule. The model is applied to Orchestra as well as to two simple distributed scheduling algorithms to demonstrate the importance of traffic-awareness for achieving high throughput.
