Building/environment Data/information System for Fine-Scale Indoor Location Specific Services

Cloud Platforms for Context-Adaptive Positioning and Localisation in GNSS-Denied Scenarios—A Systematic Review

“…As mentioned earlier, FC permits massive device connectivity. In this fashion, Li et al [ 62 ] make the BeDI repository system a reliable and scalable Fog implementation. This system was developed to give support to positioning systems, providing fast response to hundreds of thousands of devices.…”

“…OBEX protocol thus allows to exchange data and control messages between devices through a wireless communication [ 86 ]. For instance, this protocol is used in [ 62 ] to exchange the position information between the Lbeacons and mobile devices.…”

“…Generally, multiple Zigbee nodes are deployed in an environment as a network in order to determine the device position. For instance, Li et al [ 62 ] deployed Lbeacons which contain Bluetooth and Zigbee components. In this kind of implementations, one node is the coordinator, which manages the Zigbee network connection, and is also responsible for collecting data from the nodes.…”

“…Scalability [ 62 , 110 , 120 , 123 ]: It is the ability of increasing the capacity of the platform in terms of operational area, position technologies supported or number of concurrent users without inhibiting the performance. Only four works have analysed/considered this dimension in their platforms.…”

Cloud-based Indoor Positioning Platform for Context-adaptivity in GNSS-denied Scenarios

“…FC also enables massive device connectivity and centralizes the computing capabilities closer to the user devices, which improves response time. This advantage has been exploited by [49] and [16]. The platform developed by [49] permits thousands of devices to be connected to their indoor positioning platform without reducing its performance.…”
