自组织网络是人工智能最有趣的发展之一。在机会网络中，移动的节点能够彼此通信，即使连接它们的路由从未存在。此外，节点不应该拥有或获得任何知识的网络拓扑结构，这（相反）是必要的，在传统的MANET路由协议。路由是动态构建的，而消息在发送方和目的地之间的途中，并且任何可能的节点都可以被机会主义地用作下一跳，只要它可能使消息更接近最终目的地。这些需求使得机会网络成为一个具有挑战性和前景的研究领域。在本文中，我们调查了最有趣的案例研究有关的机会网络和讨论和组织的主要路由和转发方法在这个充满挑战的环境中的分类。最后，我们设想进一步的可能方案，使机会网络的一部分，下一代互联网。
Opportunistic networks are one of the most interesting evolutions of MANETs. In opportunistic networks, mobile nodes are enabled to communicate with each other even if a route connecting them never exists. Furthermore, nodes are not supposed to possess or acquire any knowledge about the network topology, which (instead) is necessary in traditional MANET routing protocols. Routes are built dynamically, while messages are en route between the sender and the destination(s), and any possible node can opportunistically be used as next hop, provided it is likely to bring the message closer to the final destination. These requirements make opportunistic networks a challenging and promising research field. In this article we survey the most interesting case studies related to opportunistic networking and discuss and organize a taxonomy for the main routing and forwarding approaches in this challenging environment. We finally envision further possible scenarios to make opportunistic networks part of the next-generation Internet.
