Research ArticleOpen accessAll words, across the recordA New Distance Based Route Maintenance Strategy for Dynamic Source Routing ProtocolMuhammad F. Sjaugi, Mohamed Othman, Mohd. Fadlee A. RasidAlthough DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from the route cache. If alternative routes are not available, the source node, then, will enter route discovery phase to find new routes. We introduced a new … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,314 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordProvisioning QoS in Virtual Private Network using Dynamic SchedulingR. Ravi, S. RadhakrishnanActive and programmable networks change the functionality of routers and switches by using VPN endpoints and active packets. The authors present a new packet scheduling scheme called active scheduling to control and maintain QoS parameters in virtual private networks (VPNs) within the confines of adaptive and programmable networks. In active scheduling a VPN endpoint on the router monitors the accumulated … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,730 accessesView PDFCite

BaraniRainfall-runoff models are nonlinear processes according to the sequential and spatial distribution of the rainfall. So, it is difficult to explain the response of catchments systems with the simple models. In the present work simulation of the rainfall-runoff processes have been carried out by the Artificial Neural Networks (ANN) and the HEC-HMS models. The ANN models of Multi Layer Perceptron … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,528 accessesView PDFCite

QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,417 accessesView PDFCite
