Caching for Mobile Communicationervices (PCS) network. The challenge of caching routing information for mobile clients lies in the uncertainty of the length of time that the information remains valid. We use expiration timestamps to safeguard against using stale cached data. We study a variety of caching algorithms and a variety o

Efficient Cache Management Protocol Based on Data Locality in Mobile DBMSsbandwidth wireless channel. As the server in mobile environments may not have any information about the state of its clients’ cache(stateless server), using . to transmit the list of updated data to numerous concurrent mobile clients is an attractive approach. In this paper, a new caching method is
