INTRODUCTION A sensor network is an infrastructure comprised of sensing (measuring), computing, and communication elements that gives an administrator the ability to instrument, observe, and react to events and phenomena in a particular environment. The supervisor typically is a civil, governmental, commercial , or industrial body. The environment can be(More)
This study aims at highlighting the Routing and Wavelength Assignment (RWA) problems in WDM Optical networks and describes the Routing Algorithms and their performance comparison. Since routing decisions play an important role in evaluating the blocking performance of a network it is critical to choose a wavelength assignment scheme that should take into(More)
— In this paper, simulations are performed to reaffirm the relationship between the resistivity and the thickness of the Hydrocarbon reservoir by considering double layers of Hydrocarbon in seabed logging application. In order to establish this correlation, various simulation models are carried out using Computer Simulation Technology (CST) tool and the(More)
— Marine controlled source electromagnetic (CSEM) sensing method used for the detection of hydrocarbons based reservoirs in seabed logging application does not perform well due to the presence of the airwaves (or sea-surface). These airwaves interfere with the signal that comes from the subsurface seafloor and also tend to dominate in the receiver response(More)
The inability of wavelength conversion between links in All-Optical networks causes congestion and hence results in Packet loss. We have Proposed a GMPLS-Based All-Optical networks that would dynamically locate path for switching in case of congestion, using maximum utilization of Control Plane resources thus ensuring guaranteed QoS. This paper presents the(More)
