This paper presents a novel approach based on clustering algorithms in combination with the location area (LA) scheme to solve the mobility management problem. Users' movemen...
The p-center problem is to locate p facilities in a network of n demand points so as to minimize the longest distance between a demand point and its nearest facility. We consider ...
This paper deals with facility location problems with pos=neg weights in trees. We consider two di erent objective functions which model two di erent ways to handle obnoxious faci...
We develop a simple and practical exact algorithm for the problem of locating p facilities and assigning clients7 to them within capacity restrictions in order to minimize the max...
We characterize the dynamic data management problem for location based services(LBS) in mobile environments and devise a cost model for servicing both location independent and loc...
