Location sharing is a fundamental service in mobile Online Social Networks (mOSNs), which raises significant privacy concerns in recent years. Now, most location-based service applications adopt client/server architecture. In this paper, a location sharing system, named CSLocShare, is presented to provide flexible privacy-preserving location sharing with client/server architecture in mOSNs. CSL...

Position-based routing is a promising technology for VANET. And location service is the fundamental component for the success of position-based routing. A map-based location service algorithm is proposed in this paper. It uses a predesigned hash function to map a node to a certain location, where location servers are recruited. Hence any node in the network can find location servers of others, ...

An algorithm change to the central processor of the network producing the GLD360 dataset is proposed to reduce the population of events with large (>5 km) location errors. In this study, we compare the data reprocessed using the proposed algorithm change to that from the realtime GLD360 dataset. The relative location accuracy using the National Lightning Detection Network as a reference is eval...

Location-based services (LBS) are very important mobile app services, which provide diverse mobility services for mobile users anywhere and anytime. This brings new demands, issues, and challenges in mobile application testing. Today, mobile applications provide location-based service functions based on dynamic location contexts, mobile users and their travel patterns to deliver location-based ...

Program comprehension is a study of how programmers understand existing programs. First, we delineate the research field and provide a brief overview of program comprehension theories. Then we present a literature review of program comprehension study results, techniques and tools – from overall comprehension through feature location to understanding the details and rationale behind the source ...

This paper describes an application of a dual satellite geolocation (DSG) system on identifying and locating the unknown source of uplink sweeping interference. The geolocation system integrates the method of joint time difference of arrival (TDOA) and frequency difference of arrival (FDOA) with ephemeris correction technique which successfully demonstrated high accuracy in interference source ...
