Decision fusion in wireless sensor networks under non-Gaussian noise channels is studied. To consider the tail behavior of noise distributions, we use a exponentially-tailed distribution as a wide class of noise distributions. Based on a canonical parallel fusion model with fading and noise channels, the likelihood ratio (LR) based fusion rule is considered as an optimal fusion rule under Neyman-Pearson criterion. With both high and low signal-to-noise ratio (SNR) approximation to the optimal rule, we obtain several suboptimal fusion rules, and we propose a simple fusion rule that provides robust detection performance with a minimum prior information. Performance evaluation for several fusion rules is performed through simulation. Simulation results show the robustness of the proposed simple fusion rule.
