Wireless Sensor Network (WSN) has become one of the cutting edge technologies, more attention has been paid to the further development and more applications emerging, WSNs is no longer confined to the traditional area. Due to the characters of dynamic, distribution, resource constrained, uncertainty, complexity and heterogeneity, we need a whole evaluation framework of WSNs performance, which can allow users choose and monitor the operation state. In this paper, we construct WSNPI architecture to rank and observe WSNs, which includes WSNPI Broker, Monitoring and WSNs Catalogue. We offer a more comprehensive evaluation index system including accountability, agility, cost, security and privacy, then build a cloud model and entropy weight method to evaluate WSNs performance. Finally, the proposed method has been serviced to complex simulation, and the results have indicated that the model is objective and effective. The first part is the research status and related problems. The second part is the establishment of an evaluation framework and model. The last part is the numerical example analysis and conclusion.
