SDN/NFV-enabled satellite communications networks: Opportunities, scenarios and challenges

In the context of next generation 5G networks, the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and m...

Efficient reliable IP multicasting

Unicast connections are a single connection between two computer hosts. While they may work well for one-to-one communication or non-real-time applications, these connections may not be as efficient for one-to-many or many-to-many communications. One alternative to this is IP Multicast, which allows efficient one-to-many and many-to-many communications. The focus of our research was IP Multicas...

Trajectory Optimization for Completion Time Minimization in UAV-Enabled Multicasting

This paper studies an unmanned aerial vehicle (UAV)-enabled multicasting system, where a UAV is dispatched to disseminate a common file to a number of geographically distributed ground terminals (GTs). Our objective is to design the UAV trajectory to minimize its mission completion time, while ensuring that each GT is able to successfully recover the file with a high probability required. We co...

Power-efficient multicasting in ad hoc networks

For power-constrained wireless ad hoc networks, a crucial issue in routing and multicasting is to conserve as much power as possible while still achieving good throughput performance. In this paper, we propose a class of power-efficient multicasting algorithms using a new cost function that jointly optimizes power conservation and path efficiency. Simulation results demonstrate significant perf...
