In this extended abstract we present an analytical solution for the end-to-end delay bound for multi-hop IEEE 802.15.4e-based networks. We base our derivation on the stochastic network calculus principles in order to provide performance guarantees for wireless industrial sensor networks. We validate the derived solution by simulations. Further, we show that the bound is convex, which, together with its monotonicity in the average SNR on the links, enables design of algorithms for optimal transmit power allocation. These two aspects: optimizing network operation while at the same time providing end-to-end delay guarantees, are of great importance for the development of reliable, stable and power-efficient wireless industrial networks.
