Yen-Wen Lin, Hsin-Jung Chang · 2004

The efficiency of finding the geographical location of the requesting users and locating proper service providers for the mobile clients profoundly dominates the performance of the system. In this paper, we propose a service discovery protocol supporting location based services for mobile clients with the aspects of efficient mobility management, lightweight client, dynamic subject-oriented service binding, and effective service handoff.
