Free Space Optical Communications: An Overview

Bridging the so-called “last mile” in communication networks has revived keen interest in free-Space Optics (FSO), also known as fiber-free or fiberless optics, which is a technology that transports data via laser technology. It is a line-of-sight technology that currently enables optical transmission up to 2.5 Gbps of data, voice and video through the air at long distances (4km), allowing optical connectivity without deploying fiber-optic cable or securing spectrum licenses. It is moving closer to being a realistic alternative to laying fiber in access networks. This paper presents an introduction to FSO and the current state of its technology

MARKOV CHAIN MONTE CARLO SOLUTION OF POISSON’S EQUATION

The classical Monte Carlo methods (fixed random walk, floating random walk, Exodus method) are useful in calculation potentials one point at a time. The Markov chain Monte Carlo method (MCMCM) overcomes this limitation by calculating the potential at all grid points simultaneously. This method has been used for whole field computation for problems involving Laplace’s equation. This paper extends the application of MCMCM to problems involving Poisson’s equations. The two illustrative examples are provided with hand calculation. DOI: 10.17762/ijritcc2321-8169.15012

The FUTURE INTERNET RESEARCH

The number of users connected to the Internet has grown exponentially. New applications have led to the convergence of voice and data networks. The capacity of the original Internet is rapidly becoming inadequate to handle large volumes of traffic patterns delivered by new services such as mobile communications, server virtualization, cloud services, and big data. The future of Internet heavily depends on future Internet research. The paper provides a brief introduction to future Internet research
