A probe request, sent automatically in the active scanning mode, consisting of the MAC address of the device expresses an advertisement of its presence. Mobile devices regularly broadcast WiFi probe requests in order to discover available proximal WiFi access points for connection. Briefly, we put forward an application architecture for the same. This can be useful in many governance and related matters. Essentially, on-the-move outdoor capture setups can be used to produce Wi-Fi access points and user devices related heat maps of the scanned locations. The overall exercise revealed that the air is full of WLAN/Wi-Fi traffic, and using OTM can assimilate lots of valuable data and generate relevant information for various purposes. We also found that channel hoping strategy plays an essential role in maximizing the sensed items. We found that considering other packets helps detect a more significant number of devices and APs. The sensed devices and APs counts using probe and beacon packets were compared with the sensed devices, and APs counts using the new methodology. We studied all the packet types that were captured, including Beacons and Probes. The primary focus of the study was to validate the OTM modality and the methodology of detecting devices and APs. We performed a case study of monitor mode packet capturing in an on-the-move and outdoor setup. We also propose that in OTM, devices (STA) and Access Points (APs) can be traced from other packets like CTS, ATS, and ACKs apart from beacons and frames. We propose scanning a predetermined path in an urban locality on the move (OTM) using monitor mode WLAN packet capturing. In STT mode, the beacon and probe packets extract insights about the localization of devices and occupancy estimation. The general modality of capturing and analysis in almost all available studies is to capture packets by being static (STT) at a location and indoors. Monitor mode packet capturing of WLAN is used to derive Access points and devices in the range for localization or occupancy purposes.
