The authors propose a new cache coherency scheme named HCCS (Hybrid Cache Coherency Scheme) to facilitate ubiquitous data access of mobile clients. To cope with the limitations of ubiquitous computing environments, it integrates the cache invalidation scheme using broadcast channel into the publish/subscribe-based data synchronization scheme using two-way communication channel. They present novel algorithms and system architecture for the HCCS. By integrating two schemes, the HCCS provides substantial benefits: allows updates on the mobile client which are restricted in the cache invalidation scheme using broadcast channel and disconnected operations, improves the scalability.
