1 Cloud Computing: A Review, Neeraj Chopra, Tanvir Singh, Amit Kumar
Cloud computing is the next step on the path to more efficient use of computing resources which is a mixture of the new ideas, technology and delivery models. This means that access to infrastructure such as servers, software, and data center space or network equipment; a computing platform and solution stack are all delivered cheaply and efficiently over the Internet. All of this is available instantly on demand and is billed according to usage or subscription, just like for any other utility. In this paper, we have discussed the concept of cloud computing along with types, benefits, limitations and applications.
2 Coordinated Multipoint (CoMP) Reception and Transmission for LTE-Advanced/4G, Satnam Singh, Amit Kumar, Dr.Sawtantar Singh Khurmi, Tanvir Singh
Wireless data usage is increasing at a phenomenal rate and driving the need for continued innovations in wireless data technologies to provide more capacity and higher quality of service. In order to meet all the requirements of IMT-Advanced as defined by ITU for LTE-Advanced/4G, several key technology components have been investigated 3GPP. In addition to relaying and repeater solutions to enhance coverage and cell edge data rates, Coordinated Multi-Point transmission/reception (CoMP) is considered by 3GPP as a tool to improve coverage, cell-edge throughput and system efficiency. This paper provides a brief insight in to the technologies including its architecture, working and challenges in the deployment of CoMP.
3 Distributions of Linux and its Comprehensive Comparison with Windows, Vasishath Kaushal, Tanvir singh, Amit Kumar
Todays Operating Systems (OS) are much more advanced in terms of usability, ease of use, hardware compatibility and performance. The major player in the desktop OS market is Microsoft Windows. While Microsoft claims that windows is the fastest operating system, but the open source communities like those of Linux have demonstrated using proofs that Linux is much faster than windows in various aspects. Also, with the advent of viruses, security issues were raised in front of windows which drew peoples attention towards Linux. The recent advancements in Linux have made it much more user friendly and compatible with most of the hardware platforms. This paper basically explains the distributions of Linux and performance differences of windows and Linux in similar environments.
4 IMT- Advanced: The ITU standard for 4G Mobile Communication, Amit Kumar, Dr. Yunfei Liu, Tanvir Singh, Dr. Sawtantar Singh Khurmi
The use of Information and Communication Technology (ICT) services, such as mobile phones and the Internet, continues to grow worldwide and Trends show explosive bandwidth growth of the Internet at large and for mobile broadband networks in particular. This is, consequently, driving the need for continued innovations in wireless data technologies to provide more capacity and higher quality of service. The International Telecommunications Union (ITU) has coined the term International Mobile Telecommunications-Advanced (IMT-Advanced) to identify mobile systems whose capabilities go beyond those of IMT-2000. Some of the key features of IMT-Advanced will be; Worldwide functionality & roaming, Compatibility of services, Interworking with other radio access systems and Enhanced peak data rates to support advanced services and applications (100 Mbit/s for high and 1 Gbit/s for low mobility). The IMT-Advanced systems will support low to high mobility applications and wide range of data rates, in accordance with service demands in multiuser environment. This paper provides a brief insight in to the IMT-Advanced standards and its key requirements which will be a pathway to next generation of wireless communication or 4G.
5 Sustainability in Wireless Mobile Communication Networks through Alternative Energy Resources, Amit Kumar; Dr. Yunfei Liu; Dr. Manu Sood; Tanvir Singh; Sunder Gopal Singh
The combination of rising energy costs and our insatiable appetite for technology advancements will lead to significant environmental impact unless aggressively addressed by a unified strategy. The explosive development of ICT (information and communication technology) industry has emerged as one of the major sources of world energy consumption. In fact ICT industry ranks among the top energy consumers, with 2% to 10% energy consumption in the world. This paper addresses the energy optimization of wireless mobile networks through alternative energy resources in wireless mobile communication to tread the path of energy sustainability. The study includes the overview of alternative energy resources like wind power, solar power, including their economic, environmental and social impact on wireless mobile communication networks.
