Dependency and Link Diversity Placement for Reliable Wireless Diamond Networks

Dependency of link failures in wireless networks impact the end-to-end reliability. Placing independent links can improve the guaranteed reliability significantly. However, it is costly and resource in-efficient. Therefore, we study an idealized wireless diamond network with dependent link failures and compute worst-case reliability for different link diversity placement strategies. A complete characterization of the reliability as a function of the marginal probabilities is provided. Numerical results show the interesting switching behaviour of optimal placement and achieved reliability as a function of the marginal probabilities.
