A Lightweight Coordination Middleware for Mobile Computing

This paper presents Limone, a new coordination model that facilitates rapid application development over ad hoc networks consisting of logically mobile agents and physically mobile hosts. Limone assumes an agent-centric perspective on coordination by allowing each agent to define its own acquaintance policy and by limiting all agent-initiated interactions to agents that satisfy the policy. Agents that satisfy this acquaintance policy are stored in an acquaintance list, which is automatically maintained by the system. This asymmetric style of coordination allows each agent to focus only on relevant peers. Coordination activities are restricted solely to tuple spaces owned by agents in the acquaintance list. Limone tailors Linda-like primitives for mobile environments by eliminating remote blocking and complex group operations. It also provides timeouts for all distributed operations and reactions, which enable asynchronous communication with agents in the acquaintance list. Finally, Li...
