Replicated Data Management in Mobile Environments:
Anything New Under the Sun?

Hector Garcia-Molina
Database Group Faculty


The mobile wireless computing environment of the future will contain large numbers of low powered palmtop machines. Replication will be an essential technique in this environment, adding availability to the system. In this talk I will discuss the existing techniques for replicated management and discuss their applicability to mobile systems. In particular, I will argue that not many changes are needed to "traditional" algorithms to cope with mobility, in spite of the many papers recently published on data management in mobile environments.
