在未来，许多服务于不同应用的无线网络将在相同的环境中共存。今天，无线网络大多以一种相当机会主义和/或自私的方式进行优化：优化方法只使用网络和环境的本地视图，因为它们试图在自己的网络内实现最佳性能。优化通常仅限于单层，网络之间的协作仅通过使用网关来实现。在这篇文章中，我们提出了一种支持独立网络之间合作的替代范式，称为共生网络。这种新的范例可以采取多种形式，例如共享网络资源、共享用于公共路由目的的节点以及共享(联网)服务。共生网络解决方案跨越网络边界运行，而不是优化单个网络内的网络参数。网络之间的参数被优化，公共协议被开发，导致对稀缺的网络资源进行更全局的优化。在本文中，我们描述了几种可以从共生网络中获益的场景，并说明了一种支持跨网络边界操作的网络协议的策略。最终，通过网络边界的消失和跨层/跨节点/跨网络合作的引入，共生网络将合作的概念带到了一个新的水平，为真正的网络共生铺平了道路。
In the future, many wireless networks, serving diverse applications, will co-exist in the same environment. Today, wireless networks are mostly optimized in a rather opportunistic and/or selfish way: optimizations methods only use a local view of the network and environment, as they try to achieve the best performance within its own network. The optimizations are very often limited to a single layer and cooperation between networks is only happening through the use of gateways. In this paper, we suggest an alternative paradigm for supporting cooperation between otherwise independent networks, called 'symbiotic networking'. This new paradigm can take many forms, such as sharing of network resources, sharing of nodes for communal routing purposes and sharing of (networking) services. Instead of optimizing network parameters within the individual networks, symbiotic networking solutions operate across network boundaries. Parameters are optimized between the networks and communal protocols are developed, leading to a more global optimization of the scarce network resources. In this paper, we describe several scenarios which can profit from symbiotic networking and illustrate a strategy for supporting networking protocols which can operate across network boundaries. Ultimately, through the disappearance of network boundaries and the introduction of cross-layer/cross-node/cross-network cooperation, symbiotic networks takes the notion of cooperation to a new level, paving the way for a true network symbiosis.
