Wireless sensor network (WSN) is widely applied in many fields since its emergence.However, the limited resources of a sensor, especially limited battery life, limited bandwidth and limited processing power, are the main challenges for deploying and operating WSNs.This paper proposes a novel architecture based on cloud computing for wireless sensor network, which can improve the performance of WSN.Based on this architecture, a cloud acts as a virtual sink with many sink points that collect sensing data from sensors.Each sink point is responsible for collecting data from the sensors within a zone.Sensing data are stored and processed in distributed manner in cloud.Our simulation results show that the proposed architecture improves the performance of WSN, e.g., reduced packet transmission error rate, decreased number of end-to-end hops, and improved efficiency of energy consumption.
