Abstract: Concerning the research of the efficient strategies for sensor data uncertainty processing, the diversity and hierarchy of sensor data uncertainty were analyzed. Three kinds of Agents, named sensor Agent, cluster and analyzer Agent, sink and decision-maker Agent, were designed. The hierarchically corresponding relation between sensor data uncertainty and multi-intelligent-Agent was also investigated. Furthermore, each Agent was specifically defined as an abstract entity with two component coordination modules on correspondence and local processing of uncertain data, as well as the intelligent characteristics combination of Wireless Sensor Network (WSN) and Rough Set Technology (RST), and then a hierarchical multi-intelligent-Agent model of sensor uncertainty coordination was put forward. Finally, a relevant implementation algorithm and illustrative analysis were given. The results verify the flexibility and practicability of such an intelligent model with hierarchical mechanisms to coordinate different kinds of complicated sensor data uncertainties.
