A Review on Advancements in Optical Communication System

Communication systems are revolutionized by the tremendous research being done in this direction. The need is the mother of the invention. The need of data transfer in increasing every day. There is the big demand for the fast optical communication systems. The optical fibers have the big potential of carrying the different channels which can transmit the data at amazing speed. In this work we have studied the research done in the field of technological development taking place in fiber communication system. The focus is on the use of fiber link as a modern medium of communication in the optical range.Communication system, Optical data transfer, Channel, Fiber link, Optical range

The Continuous Linked Structure Flooding in MANET

In some applications for adhoc networks optimal dissemination is a key issue (e.g. service discovery, network management). In this paper,  we are creating  and exploiting continuous (sub) structures to achieve an efficient (as far as low network resource usage is concerned) dissemination by building a two-layer protocol. Firstly, single-hop clusters, among continuous- connected  devices, are created.  Secondly,  on  top  of  those clusters, inter-cluster relays (ICR) are determined. This leads to an overall continuous-connected structure. The results show that the proposed continuous linked structure flooding (CLSF) protocol efficiently disseminates data among continuous nodes. Interestingly with growing density both the number of forwarding nodes and the bandwidth used remain comparatively low. Therefore we plan to use CLSF as a basis for a continuous service discovery.
