“…OppNets are presented in [87] as decentralized networks designed to take advantage of any possible communication opportunity presented by encounters between nodes. The words "OppNet" and "DTN" have often been used interchangeably in literature, thus there is need to clarify the frequent confusion among these concepts.…”

“…Opportunistic networks can be seen as good examples of distributed systems [9], which can be simulated and analyzed with the help of oracles that have the capability of delivering different kinds of network measures without delay, throughout the network. Mechanisms that provide information to predict the device and traffic behavior, and which are difficult or impossible to gather in realistic scenarios, are known as oracles [7].…”

Most of the existing opportunistic network routing protocols are based on some type of utility function that is directly or indirectly dependent on the past behavior of devices. The past behavior or history of a device is usually referred to as contacts that the device had in the past. Whatever may be the metric of history, most of these routing protocols work on the realistic premise that node mobility is not truly random. In contrast, there are several oracles based methods where such oracles assist these methods to gain access to information that is unrealistic in the real world. Although, such oracles are unrealistic, they can help to understand the nature and behavior of underlying networks. In this paper, we have analyzed the gap between these two extremes. We have performed max-flow computations on three different opportunistic networks and then compared the results by performing max-flow computations on history generated by the respective networks. We have found that the correctness of the history based prediction of history is dependent on the dense nature of the underlying network. Moreover, the history based prediction can deliver correct paths but cannot guarantee their absolute reliability.

“…In [7] the authors introduce the concept of oppnet as an applicationoriented network to support several mobile work scenarios. Then, they describe an oppnet as a peer-to-peer network [8], which can be used to improve effectiveness and efficiency of emergency preparedness and response activities [9]. However such research works do not analyze the efficiency or effectiveness of the proposal.…”

Abstract-VHF radio systems commonly used to support search and rescue activities after disasters limit the flow of information among response teams deployed in the field. It generates islands of information that jeopardizes the coordination and effectiveness of the response activities. This article proposes a communication model that uses opportunistic networks and real-time messages delivery to help address such limitation. Since the communication model is computable, it is possible to diagnose the flow of information expected for a particular work scenario. The diagnose results allow identifying elements that could help improve the information flow in such scenario. This proposal allows first responders to address the stated problem during the phases of preparedness, response and recovery from a disaster.
