Coordination Middleware Supporting Rapid Deployment of Ad Hoc Mobile Systems

This paper addresses 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 domain with minimal development effort. This technique allows developers to build highly-tailored coordination models while leveraging 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 implementation base for our veneers. These veneers cover diverse areas in ad hoc mobility: service discovery and provision, event registration and distribution, and secure tuple space access.
