In this paper, we propose a novel end-to-end QoS guaranteed approach in Cognitive Mobile Ad hoc Networks (MANETs). A "black box" concept is adopted in our approach. End-to-end QoS condition is reflected by some typical QoS parameters, QoS guaranteed is implemented by the adjustments of the tunable parameters in protocol stack and the complex mechanism(More)
A novel topology control approach for cognitive wireless networks is proposed in this paper. It includes sensing, decision-making and acting process. Sensing process is to collect necessary local information which will be used in the decision-making stage. Decision-making process uses game theory to decide the best moving positions of nodes. A local utility(More)
Internet technologies are making rapid progress, but achieving high performance of network application over the WAN remains a challenge. When branch office’s workers access enterprise applications locating in data center, the performances drop dramatically. To solve this problem, many hardware accelerators are produced. In this paper, we introduce a(More)
