In this paper, the authors study the structure of WiMAX mesh networks and the influence of tree structure on the performance of the network. From a given network graph, they search for trees, which fulfill some network, QoS requirements. Since the searching space is very huge, they use genetic algorithm ...Download Now
Many data mining applications, ranging from Spam filtering to intrusion detection, are forced with active adversaries. Adversary deliberately manipulate data in order to reduce the classifier's accuracy, in all these applications, initially successful classifiers will degrade easily. In this paper the authors model the interaction between the adversary and the ...Download Now
A very efficient approach to increase the QoS and capacity of wireless communications is to control the transmit powers. The existing power control schemes are mostly designed for power adjustment in environments that the channel is varying slowly. However, when the user channels vary very fast these methods fail to ...Download Now
It has been shown that the well-known cutset bounds can be achieved for deterministic wireless networks by performing random coding at each intermediate node. The complexity and forwarding overhead of random coding scheme prohibits its application in practice. Recently, a practical low complexity alternative, rotational coding scheme was proposed in ...Download Now
