A Mobile Agents Based Architecture for the Distributed Processing of Continuous Location Queries in a Wireless Environment: Performance Evaluation

With the current advances of mobile computing technology, we are witnessing an explosion in the development of applications that provide mobile users with a wide range of services. Of special interest are those applications that exploit the particular features of mobile environments to provide the user with context-aware information. In particular, we focus on location-dependent queries, which are still a subject of research mainly due to the lack of an architecture that is well-adapted to deal with continuous location queries in an efficient way. In this paper we present the distributed architecture, based on mobile agents, that we propose to process continuous location-dependent queries in mobile environments. We then evaluate our proposal, showing that the system achieves a good precision and scales up well.
