This letter examines the lower bound on localization error, which is an important performance measure for localization algorithms. Unlike some previous works based on the circular coverage model, we consider a more realistic scenario where radio propagation is subject to log-normal shadow fading. In this letter, we present an analytical expression for the distribution of lower bound on localization error for any range-free localization algorithm in WSNs. Finally, the derivation is validated through simulations.
