Due to the proliferation of multimedia objects and the subsequent need for managing a large number of multimedia objects within mobile client/server computing environments, there may exist multiple physical copies of the same data object in client caches at the same time with the server as the primary owner of all data objects. This brings new challenges of dealing with caching multimedia data for mobile clients. Invalid-access prevention policy protocols developed in traditional DBMS environment have to be extended to ensure that the serializability involving data updates is achieved in mobile environments. Toward this goal, we have performed analysis, proposed three extended protocols, and conducted experimental studies under the invalid-access prevention policy in mobile environments, to meet the serializability requirement in a mobile client/server environment that deals with multimedia objects. These three protocols, referred to as extended server-based two phase locking (ES2PL), extended call back locking (ECBL), and extended optimistic two phase locking (EO2PL) protocols, have included additional attributes to ensure multimedia object serializability in mobile client/server computing environments. In this paper, the rationale of developing these extended protocols, the basic idea behind the extension, a sketch of experimental studies, as well as the overall observation, are presented.
