—A novel decentralized neural network (DNN) controller is proposed for a class of large-scale nonlinear systems with unknown interconnections. The objective is to design a DNN for a class of large-scale systems which do not satisfy the matching condition requirement. The NNs are used to approximate the unknown subsystem dynamics and the interconnections.(More)
Available congestion control schemes, for example transport control protocol (TCP), when applied to wireless networks results in a large number of packet drops, unfairness with a significant amount of wasted energy due to retransmissions. To fully utilize the hop by hop feedback information, a suite of novel, decentralized, predictive congestion control(More)
Dynamic key distribution has been proposed as an alternative for the pre-deployment of keys in wireless sensor networks. The keys are generated through the collaboration of the nodes in the network. Each participating node sends a partial key to a Head Cluster Head that later calculates the sub-network key and distributes it. The advantage of this approach(More)
Web mining is an active research area which mainly deals with the application on data mining techniques on the data that is provided by the internet, the World Wide Web(WWW). The Information provided by the internet could be in either webpages, links structure of WWW or Web server logs. Web content mining, Web usage mining and Web structure mining are the(More)
Resource constraints require that ad hoc wireless networks are energy efficient during transmission and rate adaptation. In this paper we propose a novel cross-layer energy-efficient rate adaptation scheme that employs Dynamic Programming (DP) principle to analytically select the modulation scheme online. The scheme uses channel state information from the(More)
