In this paper, we discuss TCP congestion control in the future heterogeneous mobile Internet where various access links such as a wireless LAN and a cellular network are integrated. Vertical handover (VH), which is a handover technique between different types of access links, is one of the most important technologies. However, the vertical handover(More)
SUMMARY This survey summarizes the state-of-the-art research on network coding, mainly focusing on its applications to computer networking. Network coding generalizes traditional store-and-forward routing techniques by allowing intermediate nodes in networks to encode several received packets into a single coded packet before forwarding. Network coding was(More)
We investigate the use of compressive sampling for networked feedback control systems. The method proposed serves to compress the control vectors which are transmitted through rate-limited channels without much deterioration of control performance. The control vectors are obtained by an &#x2113;<sup>1</sup>-&#x2113;<sup>2</sup> optimization, which can be(More)
Keywords: Sketch-based 3D model retrieval Evaluation SHREC contest Large-scale Benchmark a b s t r a c t Sketch based 3D shape retrieval has become an important research topic in content based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on a(More)
This paper considers a fairness issue between uplink and downlink flows in IEEE 802.11 wireless LANs, where uplink flows dominate over downlink flows in terms of wireless bandwidth usage. As a solution to this unfairness, the authors propose modifying the IEEE 802.11 MAC protocol at access points (APs). Our scheme dynamically controls the minimum contention(More)
—A significant amount of wireless traffic will be carried in the Internet, and wireless connections need to share the network resources with wired connections. However, in a wireless network environment, TCP, one of the most important transport protocol of TCP/IP, suffers from significant throughput degradation due to the lossy characteristics of a wireless(More)
