Understanding code mobility
TL;DR: A conceptual framework for understanding code mobility is presented, centered around a classification that introduces three dimensions: technologies, design paradigms, and applications that support the developer in the identification of the classes of applications that can leverage off of mobile code, in the design of these applications, and in the selection of the most appropriate implementation technologies.

Managing update conflicts in Bayou, a weakly connected replicated storage system
TL;DR: Bayou as discussed by the authors is a replicated, weakly consistent storage system designed for a mobile computing environment that includes portable machines with less than ideal network connectivity, and it includes novel methods for conflict detection, called dependency checks, and per-write conflict resolution based on client-provid ed merge procedures.

Broadcast disks: data management for asymmetric communication environments
TL;DR: This work describes a new technique called "Broadcast Disks" for structuring the broadcast in a way that provides improved performance for non-uniformly accessed data and examines several "pure" cache management policies and develops and measure implementable approximations to these policies.
Broadcast Disks: Data Management for Asymmetric Communication Environments.
TL;DR: In this paper, the use of repetitive broadcast as a way of augmenting the memory hierarchy of clients in an asymmetric communication environment has been proposed, and a new technique called "broadcast disks" for structuring the broadcast in a way that provides improved performance for non-uniformly accessed data.

IEEE 802.11 protocol: design and performance evaluation of an adaptive backoff mechanism
TL;DR: Analytically study the performance of the IEEE 802.11 protocol with a dynamically tuned backoff based on the estimation of the network status and results indicate that the capacity of the enhanced protocol approaches the theoretical limits in all the configurations analyzed.

Disconnected operation in the Coda File System
TL;DR: This paper shows that disconnected operation is feasible, efficient and usable by describing its design and implementation in the Coda File System by showing that caching of data, now widely used for performance, can also be exploited to improve availability.

Continuous queries over append-only databases
TL;DR: The techniques used in Tapestry are described, which do not depend on triggers and thus be implemented on any commercial database that supports SQL and are applicable to any append-only database.

Sleepers and Workaholics: Caching Strategies in Mobile Environments
Daniel Barbará,Tomasz Imielinski +1 more
TL;DR: In this paper, a taxonomy of different cache invalidation strategies and study the impact of client's disconnection times on their performance is presented, and the authors determine that for the units which are often disconnected (sleepers) the best cache invalidization strategy is based on signatures previously used for efficient file comparison.

TL;DR: A taxonomy of different cache invalidation strategies is proposed and it is determined that for the units which are often disconnected (sleepers) the best cache invalidations strategy is based on signatures previously used for efficient file comparison, and for units which is connected most of the time (workaholics), the best Cache invalidation strategy isbased on the periodic broadcast of changed data items.
