摘　　要：由于无线传感器网络(WSN)规模大、难以人工维护等特点,仿真实验成为评价大规模无线传感器网络性能指标的重要方法。TinyOS2.x仿真工具TOSSIM只能在字符界面中进行无线传感器网络仿真,并且TOSSIM无法实现节点能量监测。针对现有TOSSIM的不足,根据改进的能耗模型,提出了一种无线传感器节点的剩余能量计算算法;并根据剩余能量计算算法,设计了TinyOS2.x传感器节点剩余能量计算组件和传感器节点应用程序,通过Qt软件开发技术设计了图形化仿真软件。实验结果表明,改进的仿真工具可以直观、准确地实现无线传感器网络实时仿真。Because of the wireless sensor networks has the characteristics of large scale network,the simulation is important performance evaluation methods for large-scale wireless sensor networks.People can study wireless sensor networks routing protocol,energy consumption model and positioning in a controlled environment through simulation.TOSSIM which is a simulation tool built on TinyOS2.x can only simulate in the character interface.We must learn the running status of the node according to the character message.And TOSSIM also does not have the function of monitoring the node energy.In order to correct the shortcomings of TOSSIM,this paper propose a kind of residual energy calculation algorithm of wireless sensor nodes.According to the residual energy calculation algorithm,this paper designs the residual energy calculation components of TinyOS2.x and application program of sensor node.With the Qt software development technology,this paper designed the graphical simulation software.The experiment result shows that the graphical simulation software,the graphical simulation software can simulate intuitively and accurately the wireless sensor networks.
