Fault-Tolerant Vector-Field Consistency

In recent years there has been an exponential growth of games on mobile devices. Multi-player ad-hoc network games are not easily developed because of the inherent issues of mobile devices and ad-hoc networks, such as limited connectivity, low processing power and short battery time. Vector-Field Consistency is an optimistic consistency model which reduces network usage, by selecting important updates to propagate to replicas. VFC is enforced by Mobihoc, a middleware platform, whose goal is to ease the development of multiplayer distributed games for ad-hoc networks. In this work we extend the VFC model in order to support the entry and departure of nodes from the system, that is, to make a fault-tolerant VFC.
