“…To this end, we consider a content sharing solution enabling search and retrieval among mobile disconnected devices without infrastructure reliance. Nodes could exploit other nodes not only to share data, but also to delegate queries so as to explore the environment in a multihop delay tolerant fashion [9], [10].…”

In the era of the Internet of Everything, users with handheld or wearable devices equipped with sensing capability have become producers as well as consumers of information and services. The more powerful these devices get, the more likely it is that they will generate and share content locally, through ad hoc opportunistic connectivity, leading to the presence of distributed information sources and forwarders and the diminishing role of centralized, infrastructure-based servers. Despite this interesting portrait, the mobile and volatile nature of this network presents severe challenges demanding new networking techniques able to cope with the unpredictable and resource-constrained nature of mobile entities comprising it. In this context, we discuss novel data gathering and dissemination strategies in urban scenarios which do not rely on strict infrastructure mediation. While preserving the general aspects of our study and without loss of generality, we focus our attention toward practical applicative case studies which help us capture the characteristics of ad hoc opportunistic communication networks, and devise efficient solutions for use in real applicative contexts.

“…Contrarily, ON requires new techniques ability to cope with limited or no information about evolving dynamic network topology and scenarios. In essence, ON "is recognized as an evolution of the connected MANET paradigm that mobile nodes can communicate with each other even without a complete route established between them at any time" [16], [17]. With this dynamic and unpredictable topology, context-awareness such as network formation and connectivity can aid alleviate known key matrices deriving from irrational approaches where relevant data is not used.…”

Networks have become a big part of the critical infrastructure of most operations. Several research funding agencies are encouraging research on revolutionary networking architectures to succeed traditional inefficient networks. The ability to rapidly create advanced technological solutions in response to user demands is key action in driving the smart networking such as active/programmable network. With the advance in current virtualization network technology, it is feasible to implement the proper network that suit the complexity of any environment. This software defined network can address the limitation of conventional network in various form. Most opportunistic networks utilize locally collected knowledge about node behavior to predict the delivery probability of each node to consider forwarding decision. To date, none of the routing protocol concerns about the sensitivity level of message in the network. This paper proposes Randomized Replication based on Multilevel of Security for opportunistic network (RRMS), a routing technique of message replication based on the randomize value of replication density. In addition, the multiple level of security is utilized as matrices of message prioritization. 
