A problem with a ubiquitous device like a cellular phone is that it is not properly integrated with contemporary distributed systems. Our goal is to improve this, by enabling cellular phones as interacting clients in a distributed system. We have devised an architecture with two main components: 1) A cellular phone, and 2) a remote extensible server based(More)
For seven years, the Tacoma project has investigated the design and implementation of software support for mobile agents. A series of prototypes has been developed, with experiences in distributed applications driving the effort. This paper describes the evolution of these Tacoma prototypes, what primitives each supports, and how the primitives are used in(More)
Group communications systems have been designed to provide an infrastructure for fault-tolerance in distributed systems , including wide-area systems. In our work on master-worker computation for GriPhyN, which is a large project in the area of the computational grid, we asked the question should we build our wide-area master-worker computation using(More)
