With the emerging awareness of health care, this paper addresses the challenging research issue of healthcare sensor decision. On light of the technology combination of WSN, MAS and RST, and its contribution to the framework of healthcare sensor decision network, this work further studies the multiplicity of intelligent agent based healthcare sensor decision network, and proposes the hierarchical model DHMASDN and its corresponding agent layer built healthcare sensor decision network, attribute layer built healthcare sensor decision network and rule layer built healthcare sensor decision network. Furthermore, the tutorial algorithm and results are also given based on rule layer built healthcare sensor decision network. And as expected, the presented model, algorithm and illustrative results are demonstrated to be more helpful to enhance the integrality and reliability of healthcare sensor decision network than those of previous related works.
