Though the mobile technology has tremendous growth, the limitation of mobile devices and mobile network such as limited battery power, data traffic and network disconnections are still the major research issues in mobile computing system. The author propose an enhanced index based broadcast scheme called PTRCD (Power and Time aware Replicated Consistent Data Dissemination) by adapting caching with compression mechanism for disseminating consistent replicated mobile data to the read-write mobile clients through reduced power, time consumption of mobile clients with minimum bandwidth requirement. The proposed approach is implemented with replication technique for providing high data availability and accessibility. The experimental results prove that the performance of suggested approach is better in most cases. The key features of PTRCD system are : (1) It caches only the required data of mobile clients and the index of first data item of current broadcast cycle in compressed form to reduce the tuning time, power consumption and network communication (2) Cached data are invalidated by re-caching the re-broadcasted data items from broadcast channel with no upstream communication.
