Abstract: In this paper, we suggest a new cache consistency maintenance scheme, namely Scalable distributed cache indexing for Cache Consistency (SDCI), for mobile environments. It mainly depends on 3 key features. They are: (1) Utilization of standard bits at server and Mobile Nodes cache for maintaining cache consistency; (2) Utilization of Local Cache Standard (LC-standard) for all entries in Mobile Nodes cache after its invalidation for maximizing the broadcast bandwidth efficiency; (3) Making every valid entry of Mobile Nodes cache to whenever it wakes up. These features make the SDCI a good scalable algorithm with minimum database management overhead. By observing Comprehensive simulation results we can see that the performance of SDCI is superior to those of existing algorithms.
