AB  - In mobile database systems, caching is a crucial way to improve the performance because a
new query can be partially answered locally when the client is continuously moving around. Semantic
caching has been paid much attention in traditional database systems. However, the methods of
semantic cache management proposed in those systems are not suitable for mobile computing
environment. Moreover, although many improved semantic caching strategies for mobile computing
application have been proposed in recent years, few papers discussed semantic cache coherence control,
which is very important in mobile computing environment. In this paper, we propose some new
semantic cache model and management algorithms, which can significantly reduce the unnecessary
uplink requests and downlink broadcasts compared to previous schemes. Simulation experiments are
carried out to evaluate the proposed strategy.
