  • Abstract
    This paper develops sharp information-theoretic bounds and offers asymptotically optimal procedures for decentralized quickest change detection under different scenarios. A lower bound of the detection delay is developed in the system with limited local memory and it is proved that the decentralised CUSUM procedure with a monotone likelihood ratio quantiser (MLRQ) defined is asymptotically optimal.
