Planning and deploying a functional large scale Wireless Sensor Network (WSN) or a Network of Internet of Things (IoTs) is a challenging task, especially in complex urban environments. A main network design bottleneck is the existence and/or correct usage of appropriate cross layer simulators that can generate realistic results for the scenario of interest. Existing network simulators tend to overlook the complexity of the physical radio propagation layer and consequently do not realistically simulate the main radio propagation conditions that take place in urban or suburban environments, thus passing inaccurate results between Open Systems Interconnection (OSI) layers. This work demonstrates through simulations and measurements that, by correctly passing physical information to higher layers, the overall simulation process produces more accurate results at the network layer. It is demonstrated that the resulting simulation methodology can be utilized to accomplish realistic wireless planning and performance analysis of the deployed nodes, with results that are very close to those of real test-beds, or actual WSN deployments.
规划和部署一个功能齐全的大规模无线传感器网络（WSN）或物联网（IoT）网络是一项具有挑战性的任务，尤其是在复杂的城市环境中。网络设计的一个主要瓶颈是是否存在适当的跨层模拟器以及能否正确使用这些模拟器，以便为感兴趣的场景生成逼真的结果。现有的网络模拟器往往忽略了物理无线电传播层的复杂性，因此无法真实地模拟城市或郊区环境中发生的主要无线电传播条件，从而在开放系统互连（OSI）层之间传递不准确的结果。这项工作通过模拟和测量表明，通过将物理信息正确地传递到更高层，整体模拟过程在网络层会产生更准确的结果。结果表明，由此产生的模拟方法可用于对已部署节点进行实际的无线规划和性能分析，其结果与实际测试平台或实际WSN部署的结果非常接近。
