Location based services are services that exploit
knowledge about where user is located. Due to the mobility of mobile clients, the
location information becomes highly varying. 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.
