Social networking applications have gained huge popularity. With the widespread use of smart devices (e.g., on-board units, smartphones), these social networks are increasingly going mobile. As a result, a new trend of networking has emerged, referred to as vehicular social networking (VSN), which combines the wireless communications between vehicles with(More)
The Internet of Things (IoT) comprises a diversity of heterogeneous objects that collects data in order to disseminate information to applications. The IoT data dissemination service can be tampered by several types of attackers. Among these, the Sybil attack emerged as the most critical since it operates in the data confidentiality. Although there are(More)
The popularity of vehicular applications, enhancing road traffic and user comfort, has instigated commuters to use short-range connectivity, e.g. WiFi, to opportunistically share content based on their interests. Recent works have proposed content dissemination protocols aiming mainly to optimize throughput and fan-out delay, without considering content(More)
Recent work has shown that content dissemination protocols in vehicular networks can achieve throughput and fan-out delay optimization by either simple network flooding or destination-driven dissemination. While those content dissemination schemes work well, they require all nodes in the network to forward every data packet, which has inherent(More)
Opportunistic communications present a promising solution for disaster network recovery in emergency situations such as hurricanes, earthquakes, and floods, where infrastructure might be destroyed. Some recent works in the literature have proposed opportunistic-based disaster recovery solutions, but they have omitted the consideration of mobile devices that(More)
Mobile devices connections to heterogeneous networks require the management of the network interfaces, as well as addressing service for each access network. However, the frequent association and dissociation of devices to the network and several communications patterns hamper the address control and negotiation. In general, addressing strategies for(More)
The integration of social networks with mobile communication has led to the rise of a new paradigm, the mobile social network (MSN). Recently, MSN has emerged as a new hot spot of research attracting much interest from both academia and industrial sectors. For instance, MSN opens new horizon for information diffusion-based applications such as viral(More)
The rapid increase of portable devices providing a multitude of mobile applications have led to excessive cellular traffic demands and consequently to the overload of cellular networks. Recently, migrating this traffic by opportunistic vehicular networks has attracted a great interest and appeared as a promising solution. Indeed, only a limited set of(More)
