In this correspondence, we analyze the effects of noisy links on steady-state performance diffusion least-mean-square (LMS) adaptive networks. Using established weighted spatial-temporal energy conservation argument, derive a variance relation which contains moments that represent links. We evaluate these and closed-form expressions for mean-square deviation (MSD), excess error (EMSE) (MSE) to explain at each individual node.
