Posted in: IEEE 2017, NS2
Efficient and Privacy-preserving Polygons Spatial Query Framework for Location-based Services Abstract With the pervasiveness of mobile devices and the development of wireless communication technique,location-based services (LBS) have made our life more convenient, and the polygons spatial query, which can provide more flexible LBS, has attracted considerable interest recently. However, the flourish of polygons spatial query still faces many challenges including the query information privacy. In this paper, […]

Comments Off on Enhanced Indoor Location Tracking Through Body Shadowing Compensation
Posted in: IEEE 2017, NS2
Enhanced Indoor Location Tracking Through Body Shadowing Compensation Abstract This paper presents a radio frequency (RF)-based location tracking system that improves its performance by eliminating the shadowing caused by the human body of the user being tracked. The presence of such a user will influence the RF signal paths between a body-worn node and the receiving nodes. This influence will vary with the user’s location and […]
