Reliability Analysis of Wireless Real-Time Control Networks

Probability of successful delivery under deadline constraints is one of the most important performance measures in a wireless real-time multihop control and sensor network. In this paper we approach the problem of determining the probability of successful packet delivery by calculating the per-link outage probability for different fading channel models. We provide easily computable results for the end-to-end reliability for two different physical layer designs. Furthermore, we show that incorporating physical layer information into routing and scheduling decisions can result in significant performance improvements when strict deadlines are imposed on the system.
