Caching is a key technique for improving data retrieval
performance of mobile clients in mobile environments. The
emergence of robust and reliable peer-to-peer (P2P) technologies
now brings to reality what we call "cooperative
caching" in which mobile clients can access data items from
the cache in their neighboring peers. This paper considers
a COoperative CAching scheme for mobile systems, called
COCA. A cache signature scheme is devised for COCA that
provides hints for the mobile clients to determine whether
a required data item is cached by their neighboring peers
based on their local state. The trade-off between the improvement
in system performance and the overheads of the
cache signature scheme in COCA is discussed. The performance
of COCA with and without the cache signature
scheme is evaluated through a number of simulated experiments.
COCA is shown to be capable of effectively reducing
the number of server requests and power consumption,
as well as shortening the access latency as the number of
neighboring peers increases. The inclusion of cache signature
scheme further improves on the access latency.
