A single spatial phase filter that discriminates multiple channels at the output of mode division multiplexing system is shown. Excellently low crosstalk performance is reported for 4 × 4 and 8 × 8 systems.
RFID (Radio Frequency Identification Technology) is a field of computerizing recognition process that is progressively gaining thrust in recent years and is now being seen as a means of enhancing data handling procedures, complimentary in many ways to other data capture technologies such as bar coding. A variety of devices and associated systems have been developed to satisfy a broad series of applications...
The Second IEEE/IFIP South Central Asian Himalayas Regional International Conference on INTERNET AH - ICI 2011 invites high-quality recent research results in the areas of Home and Health networking, Electronic commerce, Mobility and Mobile Payment, Broadband access, satellite services, rural communications and Mobile and Wireless Communications, optical communications and networking, architectures,...
Educational network interconnects various academic and research institutions. It provides a platform for knowledge sharing between different institutions. It can be implemented via National Regional Educational Network. For the sustainability of any educational network, active stakeholders play a vital role. These stakeholders could be considered as the major contributors of a knowledge base. The...
Many shortest path routing protocols have been proposed neglecting the effect of lower layers. Here, the Modified Ad-hoc On Demand Distance Vector routing based on Bit Error Rate (MAODV-BER) is proposed, where the route discovery of AODV has been modified to achieve the stable route by obtaining Bit Error Rate (BER) information from physical layer through cross-layer approach. Due to the use of multimedia...
The low cost solar power requiring for mobile transmitter/receiver tower antennas in remote areas with low traffic density and other uses in village sites, is developed. The power provides coverage to large areas having the mega cells presenting radii in the range of 100–500 km. The solar cell assembly parameters considering the top glass plate, thickness of the EVA film, back cover material, and...
This paper concentrates on the generic automation tool development for automating the process of validation of tools developed by Cisco. Cisco Smart Automation Tool can be used by engineers to automate the process of validating the tools that were developed by them. Cisco Smart Automation Tool reads the validation statements written by the developer or execution engineer from a text file or an excel...
Wireless Sensor Networks (WSNs) are composed of many sensors which are densely or sparsely deployed to get the necessary information. They are constraint on resources such as energy, memory, computational speed and communications bandwidth. Particularly power is another major issue in WSNs, therefore main stress has been given to minimize the number of transmission to extend sensor service time in...
Recommendation systems apply statistical and knowledge discovery techniques to the problem of making product recommendations and they are achieving widespread success in E-Commerce these days. A successful recommendation system fulfils several purposes and the choice of the methodology significantly influences the quality of recommendations and other aspects including scalability. As the volume of...
In today's communication scenario, high data rate single-carrier transmission may not be feasible due to too much complexity of the equalizer in the receiver. To overcome the frequency selectivity of the wideband channel experienced by single-carrier transmission, multiple carriers can be used for high rate data transmission. Orthogonal frequency division multiplexing (OFDM) , is multicarrier system...
Session sidejacking is the term used to describe the theft of cookies used to authenticate the user to a web server. Session sidejacking attack is a form of session hijacking where the hacker uses packet sniffers to listen to the traffic between the client and server to steal the session cookie. Most of the websites use Hypertext Transfer Protocol Secure (HTTPS) only for Login purpose in order to...
In this work, a free space optical (FSO) communication link for the ground-to-train system is experimentally demonstrated in the laboratory environment. The system can be used to provide high speed broadband services on fast moving trains. A line of sight (LOS) FSO communications link is presented and the measured Q-factor performance along the rail track for the prototype system is given. A downlink...
There are various types of search techniques developed so far for searching the numbers, searching strings and others. Searching in large database containing huge collection of data is done (in most of the cases) using numerical indexes. Though there are many efficient search methods available still they are not ideal. The ideal search is the one that performs search in constant time ie. O(1). Till...
The electrocardiogram (ECG) is an important bioelectrical signal which gives valuable information about the functional aspects of the heart both in normal and abnormal conditions. For several decades a considerable amount of research activity has been directed towards advancement in the clinical diagnosing of this disease using surface ECG and symptoms. This paper compares different methods that have...
The key focus of our work is to analyse some jitter control algorithms. We study a jitter control algorithm proposed by Mansour et. al [1] for networks with guaranteed quality of service (QoS) from a competitive analysis point of view. The authors have analysed the proposed algorithm (on-line algorithm) and also compared its performance to the off-line algorithm. In this paper, the analysis of the...
In recent years the attack vectors in the network world have increased many fold with the increased usage of Internet and with the exponential growth of various applications. Network Intrusion Detection System (NIDS) is one of the most sought after system by security experts in safeguarding the network from both external and internal attacks. NIDS works mainly in two modes: Online and Offline. Online...
Energy efficiency is a critical factor for operation of a wireless sensor network. In general, wireless sensor networks perform clustering and routing using localized neighbor information and simple rules only. In this paper, we propose an energy efficient clustering and routing method for wireless sensor networks by exploiting energy state information of neighbor sensor nodes for selection of cluster...
P2P has become a popular application among the Internet. The searching of the content and file sharing is perhaps the most popular application. An application uses flooding as their prevailing resource location method for content searching and file sharing. The basic problem with the flooding mechanism is that it creates a large volume of unnecessary traffic in the network mainly because a peer may...
