TIPS (<i>Transparent IP Sockets</i>) is a wrapping implementation of specific functions of the BSD sockets API to provide support for transparent IP mobility at the application level. Implemented on top of the transport layer it allows UDP and TCP communications to be immune to both client and server terminal migration (single and double jump). Location(More)
Current ubiquitous computing technologies provide access to customized, contextual, and location-based services. Device mobility, however, is frequently associated with communication delays, link disruptions due to signal loss, and changes in IP address. As a result, connection-oriented applications may fail and node location strategies should not rely on(More)
The Session-based IP Mobility Support [1] is a general purpose socket-based API designed to create mobility-aware applications that do not break with transmission disruptions or delays. In this paper, we present and discuss the security support provided in order to deal with threats in the phases of closed session opening and suspended session reopening.(More)
The widespread use of quadcopters as unmanned aerial vehicles (UAVs) provides a number of application possibilities, mostly using a collaborative swarm of small UAVs to optimise critical missions. The common application domains for small UAV swarms are surveillance, path planning, air-bone and as relay networks. Cooperative applications make use of the(More)
In this paper we report an investigation on potential session multipathing strategies that leverage the easy deployment of user space-based protocols. We devised an experimental session layer architecture to deal with multipathing and we implemented such architecture with 4 different libraries of asynchronous I/O processing for Linux systems: Epoll, Posix(More)

In vehicular networks many applications and services require the use of vehicle position, which is typically obtained from off-the-shelf Global Positioning Systems (GPS). However, GPS' position accuracy is low and the GPS receiver relies on line-of-sight signalling from the satellites. For the sake of application consistency, when the GPS position is not(More)
In the future, wireless access in vehicular environments (WAVE) will provide the foundation for a broad range of intelligent applications in transport, related to safety, comfort and, traffic management, to mention a few. Opportunities to instantaneously advertise and disseminate services arise with the technological advances of the vehicular networks.(More)
The widespread of small unmanned aerial vehicles (UAVs) offers more opportunities for collaborative UAV swarm to optimise missions. The common application for UAV swarms are surveillance, path planning, airborne, and relay networks. Cooperative applications make use of the UAVs' locations to make decisions. However, the question of vulnerability to security(More)
A wireless connectivity island is a geographic area covered by a particular wireless ISP. Nowadays, mobile users possessing multi-homing mobile devices can have IPconnectivity almost everywhere, while being on the move. In terms of vertical handover, these users jump from a connectivity island to another that could differ by communication technology, access(More)
