This paper presents the current scenario of energy availability in a typical rural telecom system and proposes green energy utilization in rural telecom sector in India. The paper discusses the renewable energy source as the best alternative for rural telecom to supply the required load at any given time. The technical suitability and financial viability of using green energy sources to meet en...

New technology based start-ups play a very important role in developing the economy of a country. In India, telecom sector has seen unprecedented growth over the last decade and this has led to emergence of several telecom related start-ups. However, product based B2B start-ups are rare and existing ones have to undergo several challenges in commercializing. Surprisingly not much research work ...

The random forests method is one of the most successful ensemble methods. However, random forests do not have high performance when dealing with very-high-dimensional data in presence of dependencies. In this case one can expect that there exist many combinations between the variables and unfortunately the usual random forests method does not effectively exploit this situation. We here investig...

This paper analyzes telecom consumer relationship by exploring customer switching behavior and classifying communication categories to support companies in planning applicable communication to thwart the consumer switching and improving consumer loyalty. Quantitative research is carried out by surveying 383 telecom consumers who have experienced the switching process. Findings uncover that tele...

One of the major issues in the future Internet is the integration of telecom networks with the Internet. In many countries, large Internet Service Providers (ISPs) are also telecom operators that have been focusing on providing Internet services through their telecom networks with telecom-grade mechanisms. In this article, we show that IP Multimedia Subsystem (IMS) is a telecom-grade mechanism ...

This work addresses the unification of some basic functions and thresholds used in nonparametric estimation of signals by shrinkage in the wavelet domain. The Soft and Hard thresholding functions are presented as degenerate smooth sigmoid based shrinkage functions. The shrinkage achieved by this new family of sigmoid based functions is then shown to be equivalent to a regularisation of wavelet ...

the goal of this paper is to compile strategies for a chinese international telecommunication vendor which entered into iran telecom market in the year 2000. since zte is involved with business in more than 135 countries and it is out of our power to collect huge data from all over the world, we have limited our strategies to iranian market and we will compile strategies for iran business unit...

While the notion of a Distributed DBMS has been familiar to the IT industry for several decades, within telecom networks the subscriber data management based on DDBMS technology is a novel addition to a service provider's infrastructure. Service providers are used to telecom networks that are efficient, reliable and easy to maintain and operate, in part thanks to the node model used in designin...

An extension of the non local (NL) means is proposed for images damaged by Poisson noise. The proposed method is guided by the noisy image and a pre-filtered image and is adapted to the statistics of Poisson noise. The influence of both images can be tuned using two filtering parameters. We propose an automatic setting to select these parameters based on estimated mean square error (MSE) minimi...
