一种工业无线传感器网络抗毁性仿真平台

Simulation Platform for Invulnerability of Industrial Wireless Sensor Networks

现有无线传感器网络抗毁性仿真平台未考虑工业场景中环境干扰与突发事件对网络性能的影响,难以满足工业无线传感器网络抗毁性能测试要求。针对工业无线传感器网络性能易受环境影响与抗毁性行为受事件驱动等特征,引入部署环境组件与事件生成器,并基于人工势场理论,建立网络抗毁性能与部署环境的关联关系,设计开发了工业无线传感器网络抗毁性仿真平台。实验表明,该仿真平台能够用于评估工业无线传感器网络抗毁性能。

Existing simulation platforms for industrial wireless sensor networks(IWSNs) mainly focus on the general scenario and fail to take into consideration the impacts of interference brought by external environments and emergencies on network performance, thus failing to evaluate the network invulnerability. For given the environment-impacted and event-driven features of IWSNs, the connections between network invulnerability and deployment environment are built. On this basis, a simulation platform for invulnerability of IWSNs is proposed by introducing deployment environment component and event creator. Experiments show that the platform is capable of evaluating the invulnerability of IWSNs.
