Intelligent file hoarding for mobile computers
Carl Tait, Hui Lei, Swarup Acharya, Henry Chang · 1995
Mobile computing adds a new wrinkle to the ageold problem of caching. Today's wireless links are both slow and expensive, and are not always available to a user. Therefore, when a mobile user is disconnected, a cache miss means (at best) a substantial cost in time and money, or (at worst) a complete halt to work if critical information has not been cached. Existing solutions to this problem rely on some combination of explicit hoard profiles and spying on a user's file accesses.
