Abstract Opportunistic Mobile Networks (OMNs), also known as Delay Tolerant Networks
(DTNs), refer to wireless networks in which the mobile nodes (eg, smartphones, tablets …

Sybil attacks present a unique threat in the context of Mobile Social Networks and the
Internet of Things. Existing research activity in this field focuses on developing novel …

In recent years, networked devices spread into different activities in our daily lives enabling
many innovative applications. These applications were not only computationally-intelligent …

Opportunistic Networks are envisioned to complement infrastructure-based communication
in overloaded cellular settings, in remote areas, or during and immediately after large scale …

Mobile opportunistic networks allow nodes to freely join and leave the network; hence they
are highly susceptible to security threats. The paper proposes a method for detection and …

As redes DTN são redes móveis sem fio caracterizadas por um grande atraso entre as
transmissões de mensagens e também por uma grande mobilidade entre os nós, o que …

A particularly detrimental attack ravaging campus and ad hoc networks is the Sybil attack,
where a node illegally claims more than one identity, targeting honest and genuine nodes …
