Abstract (english): Wireless Mesh Networks are a promising technique for large scale networks with low-power and high reliability requirements such as in industrial plants. The shared transmission medium requires a medium access control mechanism which reduces the amount of parallel transmission, because nearby simultaneous transmitting devices hinder the successful reception at the destination device. The common CSMA-CA mechanism cannot satisfy the reliability requirement of an industrial plant, as many messages get dropped when the channel is busy for too long.

Current standards introduce TDMA schemes for wireless mesh networks to improve the reliability with higher throughput and deterministic latency. In this work these standards are reviewed and one of the specified TDMA protocols, the deterministic synchronous multi-channel extension (DSME), is analyzed in more detail by examining its performance analytically and also by simulation. For this purpose, a simulation model was implemented, which is used to simulate an example network utilizing DSME and a promising geographic routing algorithm for a solar tower power plant.

The introduced analytical model allows to determine the maximum performance for a network using DSME. The simulation results show that DSME achieves a strongly improved packet loss probability compared to CSMA-CA.
