چکیده
∗ This research has been supported, in part, by grants from NTT DoCoMo, Inc., NJCWT (the New Jersey Center for Wireless Telecommunications), Panasonic Technologies, Inc., and Project 69931040 supported by NSFC. Abstract We have investigated the indoor geolocation based on signal strength modeling. Linear, compensated linear, and multiple regression methods have been applied to set up signal strength models by using simulated data. We have also analyzed this modeling method to better understand the relation between the location error and the signal strength error. Some important results have been obtained to help us determine proper placement of Access Points (APs) and evaluate the range of location error. A simulation experiment has been conducted based on typical parameters of IEEE802.11b MAC.

DOD-Based Indoor Localization Using BLE Beacons
This paper presents a BLE-based localization method suitable for the indoor smartphone geolocation service. In this method, a triangulation technique using Direction-of-Departure (DOD) information from the multiple BLE beacons is used for localization, where they are calculated only from the Received Signal Strength Indicator (RSSI). The outline of the proposed localization system and the exper...
متن کاملImproved Estimation of Trilateration Distances for Indoor Wireless Intrusion Detection
Detecting wireless network intruders is challenging since logical addressing information may be spoofed and the attacker may be located anywhere within radio range. Accurate indoor geolocation provides a method by which the physical location of rogue wireless devices may be pinpointed whilst providing an additional option for location-based access control. Existing methods for geolocation using...
متن کاملUsing UWB Measurements for Statistical Analysis of the Ranging Error in Indoor Multipath Environment
In this paper we use UWB measurements for bandwidths up to 3GHz to present a framework for statistical modeling of the indoor radio channel propagation characteristics that are pertinent to precise indoor geolocation using time-of-arrival (TOA) estimations. Accuracy of indoor geolocation systems relies on the strength and TOA of the direct path (DP) in the channel profile. Based on UWB measurem...
