Data rate adaptation is the process to select the optimal data rates for instantaneous channel conditions. This paper proposes a data rate adaptation technique that poses followin...
Recent research shows that significant energy saving can be achieved in wireless sensor networks by using mobile elements (MEs) capable of carrying data mechanically. However, th...
— In this paper, we propose a simple but effective VPN mechanism called RING-VPN (Ring-based Virtual Private Network) that realizes a high scalability in terms of the number of V...
— In this paper, a scheduling problem in wireless networks is considered when there simultaneously exist CBR (constant bit rate) users requiring exact minimum average throughput ...
Content Distribution Networks (CDNs) are increasingly being used to disseminate data in today's Internet aiming at reducing the load on the origin server and the traffic on t...
