Lecture Notes in Computer Science
Preserved Fulltext
Up to now, users have had to rely on an external party, typically a location service provider (LSP), for computing an optimal meeting point. ...
Our experimental results show that we provide a readily deployable solution for real life applications which can also be deployed for other geo-spatial queries and applications. ...
Introduction Internet accessibility through smartphones has fueled the increased popularity of Location Based Services (LBS). Finding a convenient meeting point for a group is a common problem. ...
