A Comprehensive Survey on Routing Schemes for High Speed Networks

--Veenu Pondwal and Himanshi Saini

It is observed that the impact of network failures is more pronounced in high speed networks. To maintain optimal network performance parameters, it is essential to deal with network routing in an efficient manner. To maintain network survivability after occurrence of failures, the routing technique implemented for high speed network should work for failure-prone networks. In this paper, a comprehensive survey of existing routing techniques in optical networks, such as Ad hoc On-Demand Distance Vector (AODV) routing, Destination Sequenced Distance Vector (DSDV) routing protocol, Dynamic Source Routing (DSR), Zone Routing Protocols (ZRP), Temporally Ordered Routing Algorithm (TORA), and Greedy Perimeter Stateless Routing (GPRS) protocol, has been presented. Each routing technique has its limitations and advantages. Implementation of a particular technique in a network is dependent on the size of the network, geographical area and network performance desired. Network performance is measured through various parameters such as Packet Delivery Ratio (PDR), link throughput, link bandwidth, delay, throughput, etc.

Performance Analysis of MIMO Detection Schemes for M-Ary QAM Modulation

--V K Chaubey, Girish Kakalwar and P C Hariprasad

Implementation of orthogonal space time coding to gain ultimate bandwidth efficiency at higher bitrate is an attractive choice to exploit the capability of Multi-Input Multi-Output (MIMO) system in wireless faded environment. The paper presents a suitable mathematical model to evaluate the performance of such a receiver under Zero Forcing (ZF) and Singular Value Decomposition (SVD) schemes for two different configurations of 2 x 2 and 3 x 3 MIMO structures. The model has been tested to evaluate the performance of 16-QAM and 64-QAM modulation schemes to establish the superior performance of SVD scheme over ZF especially at low SNR. The paper also reports comparative performance of Symbol Error Rate (SER) with respect to SNR for QPSK, 16-QAM and 64-QAM schemes to understand the qualitative and quantitative inferences for a suitable practical design.

A Comparison of Generalized Cross-Correlation Methods for Time Delay Estimation

--Ritu and Sanjeev Kumar Dhull

Time Delay Estimation (TDE) between the signals received at the spatial sensor pair has been a topic of significant importance because this estimated delay can be used as input in plenty of applications for further processing of the signal. The estimation of the delay should be accurate enough in order to avoid or minimize the propagation of the error to the subsequent stages. The generalized cross-correlation method is the most popular and widely used technique for TDE due to accuracy and low computational complexity. The paper presents a comparison of weighting functions used in generalized cross-correlation along with their simulation results. It has been shown how each weight affects the peak sharpening in the correlation function. Simulation has been carried out with different types of sound and noise. The effect of varying Signal-to-Noise Ratio (SNR) on the estimated delay has also been studied.

Performance Testing of Composite Dielectric Patch Antenna

--B Premalatha, M V S Prasad and M B R Murthy

Microstrip antennae are low profile and less weight and are preferred for conformal low profile antennae requirements. A patch using two different dielectric materials in substrate is simulated for operation at 2.5 GHz and the performance is analyzed. The effect of placement of the two materials is investigated. The gain and bandwidth values are reported and discussed. The analysis is carried out with the help of HFSS (High Frequency Structural Simulator) software.

Design and Analysis of High Gain Proximity Feed Microstrip Patch Antenna for Wi-Fi Applications

--Y Pandu Rangaiah and R V S Satyanarayana

The modern communication systems need development in antennas which have large bandwidth and low profile. Profile is the physical size of the antenna and it should be as small as possible for easy installation and operation. The paper deals with design aspects of square microstrip patch antenna with proximity feed and its properties. In this paper, simulations are carried out on C-band square microstrip patch antenna that suits Wi-Fi and bluetooth applications. With the adjusted parameters, the designed antenna exhibits maximum gain of 7 dBi and return loss –40 dB at center frequency 5 GHz. Desired patch antenna design was simulated using ANSYS HFSS software. The substrate material used for designing of microstrip patch antenna is RT Duroid 5880 and the thickness of the substrate is 1.6 mm.

A Survey of Various Reversible Binary to Gray Code Converters

--P Gowthami

Reversible logic has attained importance in the recent developments of high speed and low power digital systems. This factor calls for a performance analysis of different reversible binary to gray code converters. To know the different combinations of reversible gates used in the design for the construction of reversible binary to gray code converters, several binary to gray code converters are analyzed in this paper

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
