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)
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)
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)
