The focus of this paper is to implement four channeldense wave length division multiplexing (DWDM) system, with each channel of 10Gbps over optical span of 100Km in the presence of Four Wave Mixing (FWM) under the impact of equaland unequalchannel spacing. In this proposed work, the comparison of DWDM system with equaland unequal-channel spacing varying(More)

To sum up the advantages and counterbalance the drawbacks of various optical amplifier types, a hybrid amplifier can be made. Here a combination of two most popular and frequently used amplifiers i.e. EDFA-RFA i.e. Erbium Doped Fiber Amplifier altogether with Raman Fiber Amplifier; has been used to calculate the lowest gain variation in C band i.e. from(More)
Limited resources especially energy partially marred the massive applicability's of Wireless Sensor Networks (WSNs). As a result power effectiveness has become one of the significant topics of research. In this paper, physical layer parameters especially modulation techniques have been considered to enhance the network lifetime of WSNs. This paper proposes(More)
Cloud is emerging as a utility paradigm for effectively executing large scale distributed workflows with huge computation and data transfer requirements. The heterogeneity in cloud resources makes it challenging for scheduling workflow tasks effectively. The goal is to find an optimized mapping between individual workflow tasks and cloud resources, based on(More)
Optical Burst Switching (OBS) is one of the most important switching technologies for future IP over wavelength division multiplexing (WDM) networks. In OBS Network, the burst assembly technique is a challenging issue in the implementation of the system. Burst assembly influences burst characteristics, which negatively impacts network performance. In this(More)
Energy optimization is considered as one of the challenging research topics of Wireless Sensor Networks. Several solutions in the form of clustering, data fusion & aggregation, optimal and smart routing have come forward and it is concluded that one needs to incorporate these solutions in order to effectively optimize energy of WSNs. This paper provides(More)
We consider the extension of network lifetime of battery driven wireless sensor networks by splitting the sensing area into uniform clusters and implementing heterogeneous modulation schemes at different members of the clusters. A cross-layer optimization has been proposed to reduce total energy expenditure of the network; at network layer, routing is done(More)
