Rapid Deployment of Coordination Middleware Supporting Ad Hoc Mobile Systems

Abstract

This paper is concerned with the design and implementation of thin coordination veneers for use in the development of applications over ad hoc wireless networks. A coordination veneer is defined as an adaptation layer that customizes a general-purpose coordination middleware to a particular application domain with minimal development effort. This technique allows developers to build highly-tailored coordination models while leveraging off established models and middleware. We present three such veneers, the coordination models they embody, and the manner in which they were implemented. The Lime middleware, which supplies tuple space based coordination in the ad hoc environment, serves as the underlying implementation base for our veneers. These veneers cover diverse application areas in ad hoc mobility: service discovery and provision, event registration and distribution, and secure tuple space access.
