The Tale of Two Localization Technologies: Enabling Accurate Low-Overhead WiFi-based Localization for Low-end Phones
Ahmed Shokry, Moustafa Elhamshary, Moustafa Youssef
WiFi fingerprinting is one of the mainstream technologies for indoor localization. However, it requires an initial calibration phase during which the fingerprint database is built…
DynamicSLAM: Leveraging Human Anchors for Ubiquitous Low-Overhead Indoor Localization
Ahmed Shokry, Moustafa Elhamshary, Moustafa Youssef
We present DynamicSLAM: an indoor localization technique that eliminates the need for the daunting calibration step. DynamicSLAM is a novel Simultaneous Localization And Mapping (S…
A Fine-grained Indoor Location-based Social Network
Moustafa Elhamshary, Anas Basalamah, Moustafa Youssef
Existing Location-based social networks (LBSNs), e.g., Foursquare, depend mainly on GPS or cellular-based localization to infer users' locations. However, GPS is unavailable indoor…
TransitLabel: A Crowd-Sensing System for Automatic Labeling of Transit Stations Semantics
Moustafa Elhamshary, Moustafa Youssef, Akira Uchiyama +2
We present TransitLabel, a crowd-sensing system for automatic enrichment of transit stations indoor floorplans with different semantics like ticket vending machines, entrance gates…
semMatch: Road Semantics-based Accurate Map Matching for Challenging Positioning Data
Heba Aly, Moustafa Youssef
Map matching has been used to reduce the noisiness of the location estimates by aligning them to the road network on a digital map. A growing number of applications, e.g. energy-ef…
LaneQuest: An Accurate and Energy-Efficient Lane Detection System
Heba Aly, Anas Basalamah, Moustafa Youssef
Current outdoor localization techniques fail to provide the required accuracy for estimating the car's lane. In this paper, we present LaneQuest: a system that leverages the ubiqui…
