Abstract :
A conceptual generalization of the Wald´s sequential probability ratio test (SPRT) to a decentralized environment is presented. The local tests are chosen to be SPRT´s, which quantize the temporally independent identically distributed (IID) observations into three levels for transmission to the fusion detector. Spatial independence among the local observations is assumed. The fusion test is also an SPRT. An analysis for the decentralized scheme is developed. Performance comparisons with the centralized and other decentralized schemes are presented
