TLDR
An energy-efficient cache invalidation method, called GCORE (Grouping with COld update-set REtention), that allows a mobile computer to operate in a disconnected mode to save the battery while still retaining most of the caching benefits after a reconnection is presented.Abstract:
Caching can reduce the bandwidth requirement in a mobile computing environment. However, due to battery power limitations, a wireless mobile computer may often be forced to operate in a doze (or even totally disconnected) mode. As a result, the mobile computer may miss some cache invalidation reports broadcast by a server, forcing it to discard the entire cache contents after waking up. In this paper, we present an energy-efficient cache invalidation method, called GCORE (Grouping with COld update-set REtention), that allows a mobile computer to operate in a disconnected mode to save the battery while still retaining most of the caching benefits after a reconnection. We present an efficient implementation of GCORE and conduct simulations to evaluate its caching effectiveness. The results show that GCORE can substantially improve mobile caching by reducing the communication bandwidth (or energy consumption) for query processing.read more

Bit-sequences: an adaptive cache invalidation method in mobile client/server environments
TL;DR: The proposed BS algorithm is especially suited for dissemination-based (or “server-push”-based) nomadic information service applications and its critical aspect is its self-adaptability and effectiveness, regardless of the connectivity behavior of the mobile clients.

Replication and mobility
TL;DR: The authors address some of the questions, by proposing an adaptive replication scheme for mobile data, which is dependent not only on the distance between them but also on the cost of search necessary to determine the exact value of location.
