A family of variable offset-time based wavelength scheduling schemes for OBS edge-nodes, is proposed which performs 4–20 times better than ordinary LAUC-VF schedulers in terms of byte loss rate (ByLR). The schedulers accept a minimum and a maximum limit of offset-time along with the length of the burst as input and then return the appropriate wavelength and the exact offset-time, to be used for the...
In this paper, we propose a proactive burst assembly scheme for optical burst switching network where bursts are created in such a way that it suffers minimum loss at the immediate outgoing link. The future reservation states of individual wavelength channels are used to construct and update the availability state of the whole link as a function of time. The assembly algorithm, before assembling a...
Wireless sensor networks consisting of spatially distributed autonomous devices required to survive in unprotected environments. They are always susceptible to attack by malicious behavior of its routers (nodes) or external enemy nodes which could negatively affect secured routing and QoS and hence, vital wireless multimedia applications. In recent times, a lot of specific severe attacks have been...
