Semantic caching enables mobile clients to answer spatial
queries locally by storing the query descriptions together
with the results. However, it supports only a limited
number of query types, and sharing results among these
types is difficult. To address these issues, we propose a
proactive caching model which caches the result objects
as well as the index that supports these objects as the results.
The cached index enables the objects to be reused
for all common types of queries. We also propose an adaptive
scheme to cache such an index, which further optimizes
the query response time for the best user experience. Simulation
results show that proactive caching achieves a significant
performance gain over page caching and semantic
caching in mobile environments where wireless bandwidth
and battery are precious resources.
