Abstract
With the rapid increasing of wireless request, user mobility is a critical influence on system performance of mobile environments. Unlike conventional distributed systems, the mobility of users is the major characteristic in a mobile computing environment so that the value of data may depend on location, and processing of a query at one site may give different results than that at another. In this paper, we present the broadcast-based location dependent data delivery scheme for location-based queries. In the approach, broadcasted data objects are dynamically adjusted based on their locations, and the server broadcasts the location dependent data along with access popularity. Then, we present a data evaluation scheme, designed to reduce the query response time. Simulation experiments are conducted to compare the performance of our method with other issues. The results show that our schemes outperform the conventional strategies.
