We consider the problem of decentralized change detection using the CUSUM test. More than one sensors acquire independent signals and send their quantized version to a fusion center that uses this information to detect a simultaneous change in all sensors. By introducing a recurrence relation that defines the optimum performance of the CUSUM test for given quantization, we further optimize this measure with respect to the quantization scheme. We compare the resulting optimum test with a simple,doi:10.1109/icif.2006.301578 dblp:conf/fusion/Moustakides06 fatcat:w6cyzfoyynemze4ikmn6qvm2my
