诸如智能电话和PDA之类的个人计算设备是常见的，其捆绑若干无线网络接口，可以支持计算密集型任务，并且配备有用于产生多媒体内容的强大手段。因此，它们为我们所设想的人类普适网络提供了资源：由用户设备形成的网络，适合根据用户的兴趣和需求向用户传达丰富的多媒体内容和服务。类似于机会网络，其中的通信是建立在连接的机会，我们设想一个网络以上的这些资源，结合在一起的功能，传统的普适网络和机会网络，培养一个新的计算范式：机会计算。在这篇文章中，我们讨论了从机会网络到机会计算的演变，我们调查了机会网络最近的主要成就，并描述了机会计算的主要概念和挑战。最后，我们设想进一步可能的场景和功能，使机会计算在下一代互联网的关键球员。
Personal computing devices, such as smartphones and PDAs, are commonplace, bundle several wireless network interfaces, can support compute intensive tasks, and are equipped with powerful means to produce multimedia content. Thus, they provide the resources for what we envision as a human pervasive network: a network formed by user devices, suitable to convey to users rich multimedia content and services according to their interests and needs. Similar to opportunistic networks, where the communication is built on connectivity opportunities, we envisage a network above these resources that joins together features of traditional pervasive networks and opportunistic networks fostering a new computing paradigm: opportunistic computing. In this article we discuss the evolution from opportunistic networking to opportunistic computing; we survey key recent achievements in opportunistic networking, and describe the main concepts and challenges of opportunistic computing. We finally envision further possible scenarios and functionalities to make opportunistic computing a key player in the next-generation Internet.
