Opportunistic Networks: Challenges in Specializing the P2P Paradigm

We introduce the notion of opportunistic networks or oppnets, some of which can be considered a subclass of the peer-to-peer (P2P) networks. Initially, a relatively small seed oppnet is deployed, which grows into a bigger expanded oppnet. Oppnet growth starts with detecting diverse systems existing in its relative vicinity. Systems with best evaluations are invited by an oppnet to become its helpers. The oppnet leverages vast collective capabilities and resources of its helpers, employing them to execute diverse tasks in support of its goals. Though oppnet characteristics make them a natural fit for emergency response applications, we expect that they will prove beneficial in many other application areas. We discuss challenges in the development and use of the oppnet technology. Oppnets that use P2P interactions can be viewed as a specialization of the more general paradigm of P2P networks. To the best of our knowledge, we were the first to define and are now the first to investigate oppnets
