Abstract:

Personal Digital Assistants and Personal Computers often utilize synchronization protocols in order to maintain data consistency. These protocols operate in environments where network resources such as bandwidth, memory, and processing power are limited. In this paper a novel PDA synchronization scheme(CPISync) predicated upon recent information-theoretic research was introduced. The characteristic of this scheme was that its communication complexity depended on the number of differences between the PDA and PC. Moreover, experiments showed that the computational complexity and energy consumption of CPISync were practical and that the overall latency was typically much smaller, which played an important role in their scalability. Thus, CPISync had a potential of significantly improving synchronization efficiency for PDAs on large, heterogeneous, wireless networks.
