Sijs, J. (author), Lazar, M. (author), van den Bosch, P.P.J. (author), TNO Industrie en Techniek (author)Some crucial challenges of estimation over sensor networks are reaching consensus on the estimates of different systems in the network and separating the mutual information of two estimates from their exclusive information. Current fusion methods of two estimates tend to bypass the mutual information and directly optimize the fused estimate....conference paper 2010
