An efficient wireless access point selection algorithm for location determination based on RSSI interval overlap degree determination

Abstract: Optimally choosing wireless Access Points (APs) as urban areas become more densely packed with them becomes increasingly challenging. In WiFi-based Indoor Positioning Systems (IPS), Selecting Wireless Access Point (AP), namely, WiFi routers, is significant as the more APs that are selected, the higher the computation, energy and time cost. This is unsuitable for networking low-resource devices as part of an Internet of Things. In addition, selecting the optimum number of APs not only reduces redundant informat… Show more

“…Third, we aim to investigate the application of other state-of-art zero-shot/one-shot learning to use less samples to train the system. Fourth, we will combine our previous research using RSSI localization methods [6], [20] to raise the recognition accuracy. Fifth, we will look at more distributed AI algorithms to analyse ADL data [21], [22].…”

“…In our IPS, we also have such two phases, but after we collected the fingerprints, we select APs to improve location accuracy as some are noisey. In our previous work, 7 we proposed an interval overlap degree (IOD) determination method to do the AP selection. However, this method is based on the raw RSSI measurements, which is not suitable for ranking-based AP selection.…”

“…For example, the decision to select between multiple WiFi APs in today's end-devices is fully distributed. A client usually selects among available WiFi APs based on a single Received Signal Strength Indicator (RSSI) metric [35]. A multi-RAT selection algorithm to select between cellular networks and WiFi APs also exists in today's end-devices.…”
