Cooperative Intelligent Distributed Systems for Indoor Localization

无线传感器网络中的定位是一系列测量节点和物理对象之间空间关系的技术。定位是确定一个物体相对于另一个物体的位置的问题。路由信息是无线传感器网络的重要组成部分，通过定位可以增强路由信息。许多现实世界的应用现在需要在封闭环境中跟踪或监控物理对象，例如医院，矿山，机场和地铁。虽然全球定位系统（GPS）似乎是一个明显的跟踪解决方案，但GPS仍然相对昂贵，耗电量大，并且在室内使用时性能下降。无线传感器网络是一个解决问题的执行广域监测和监视。无线射频识别（RFID）在大型系统的监控和跟踪中至关重要。实体，从对象到用户，配备了无线传感器网络和RFID标签，以收集他们的上下文信息。在无线传感器网络中使用代理的唯一标识符提高了网络的可扩展性和可扩展性。

Localization in wireless sensor networks (WSN) is defined as the collection of techniques to measure the spatial relationship between nodes and physical objects. Localization is the problem of determining the position of an object with respect to another object. Routing information, a crucial component in WSN, is enhanced by localization. Many real-world applications now require tracking or monitoring of physical objects in closed environments, such as hospitals, mines, airports and subways. While global positioning systems (GPS) would appear to be an obvious tracking solution, GPS is still relatively expensive, power hungry and has degraded performance when used in indoor locations. WSNs are a solution to the problem of performing wide-area monitoring and surveillance. Incorporating radio frequency identification (RFID) is essential in the monitoring and tracking of large systems. Entities, ranging from objects to users, are equipped with WSN and RFID tags to gather their context information. Using agents’ unique identifiers in WSN improves network manageability and scalability.
