Basic Named Data Networks (NDN) security mechanisms, rely on two main key features. The first one is the caching mechanism where it manages to minimize both the bandwidth usage and the data retrieval delay all along with congestion avoidance by storing, in the intermediate routers, the contents recently demanded to quickly serve future consumers’ r...

In recent years, cloud computing has played an important role in accessing services around the world. Thanks to its rapid development in the IT industry it has gained huge appeal.

The concept of connecting vehicles to the Internet using the already deployed cellular network architecture has opened many avenues for research and development that are contributing significantly towards the Inte...

In the last decades, under technological progress in electronic and avionics systems, Unmanned Aerial Vehicles (UAVs) have known an increasing use in several military and civilian missions. Multiple UAVs can cooperatively carry out dangerous applications for human operators or missions where human intervention is not needed, such as surveillance an...

The main objective of Vehicular ad hoc networks (VANETs) is to make road transportation systems more intelligent in order to anticipate and avoid dangerous, potentially life-threatening situations.

VANETs currently represent one of the most prominent solutions that aim to reduce the number of road accident victims and congestion problems while improving the quality of driving. VANETs form a very dynamic open network in which vehicles exchange information and warnings about road situations and other traffic information through several routing...

The future internet will include a variety of heterogeneous wireless networks and all kinds of smart sensors connected over wireless links. The size and cost constraints on sensor nodes result in corresponding constraints on resources such as energy, memory, computational speed and communications bandwidth which in turn limits the processing and co...

In multihop ad hoc networks, TCP cannot effectively deal with the problem of packet drops caused by mobility and shared channel contention among wireless nodes. Mistaking these events for congestion degrades TCP performance. Hence we propose a new end-to-end mechanism, called TCP with Adaptive RTO+ (TCP-AR+), to assure faster recovery after non-con...
