Abstract: | 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.
