【摘要】 仿真平台对于无线传感器网络尤其是大规模无线传感器网络的性能评价是必不可少的。在分析现有仿真平台优缺点的基础上,从体系结构、应用场景、仿真流程等几方面,设计开发了基于.NET框架的无线传感器网络仿真平台WSNSim,采用MICA2节点实测能量模型和组件设计,实现对环境状态检测、突发事件处理和移动目标跟踪的仿。并在WSNSim平台上验证了改进协议SEMAC的有效性。更多还原

【Abstract】 It is necessary to develop simulation environment to evaluate the performance of Wireless Sensor Networks (WSNs), especially for the large scale WSNs. Drawbacks of current simulators are pointed out, and a new simulation environment WSNSim is designed and developed based on .Net framework from aspects of architecture, application scenes, simulation flow. WSNSim adopts experimented energy model and component based approach, which can detect condition of environment, process sporadic event and track mobile target. The effectiveness of improved protocol SEMAC is validated under the WSNSim environment.更多还原
