To apply this service, the […]
Performance of microstrip low pass filter with stub loaded Electromagnetic Band Gap ground plane Mariselvam V, Raju S Abstract A novel elliptic-function low-pass filter (LPF) is Presented, which consists of a Electromagnetic band gap on the ground plane. The Electromagnetic band gap provides the required wideband attenuation in stop band, while the slot provides steep transition from pass band to stop band. A 5.4 […]
With the popularity of broadband services of the terminal users the demands for bandwidth in the access network is rapidly increasing. Rapid increase of global data traffic and massive deployment of new networks are becoming a key environmental, social and economic issue. The access network consumes about 70% of overall network energy. Passive Optical Networks (PON) has been considered to be one of the most […]
Development of a Resilient Wireless Sensor Network for Real-Time Outdoor Applications Maneesha Vinodini Ramesh, Parvathy Rajan, Divya Pullarkat Abstract Wireless sensor networks that are deployed for any outdoor applications face the challenge of link variations. The outdoor sensor network would be affected because of unpredictable changes in the environment. The effect can vary accordingly with a single hop and a multi hop sensor network. […]
A novel approach for adaptive energy efficient transmission in WSNs S Murthy Vedireswarapu, Muni Bhaskar. Athikayala Shankar.T Abstract In wireless sensor networks (WSNs), sensor nodes work on finite capacity batteries. So, in order to increase network lifetime the mobile sensor nodes should be operated at low power. Hence, we need a novel approach for efficient scheme for transmission in WSNs. In this scheme, according […]
Pre, Post and Mix Compensation techniques for 50 Gbps Duobinary System Rupinder Kaur, Sanjeev Dewra Abstract: In this paper, the performance of duobinary system is analyzed by using different dispersion compensation techniques. The dispersion compensation techniques tested are Pre Compensation, Post Compensation and Mix Compensation. These techniques are applied to duobinary system, which operates at a bit rate of 50 Gbps. It is found […]
As was concluded on the first chapter of the work, one of the best routing protocols, which is less energy-intensive and in the same time have other good conditions, like mobility, multipath usability, effective data aggregation, and so on, is Directed-Diffusion. Thus, Directed-Diffusion is chosen as a base protocol for reaching the goals of the dissertation. The importance of the energy-efficiency characteristic in sensor networks […]
Dual band bandpass filter using Meandered ring resonator using loaded DGS Mariselvam V, Raju S Abstract Compact microstrip dual-band bandpass filter (DBBPF) with high selectivity and good suppression for wireless local area networks (WLANs) is proposed utilizing a novel embedded scheme resonator loaded ring resonator DGS. Two passbands are produced by a pair of embedded half-wavelength meandered stepped-impedance resonator (MSIR) and a quad wavelength short […]
INTRODUCTION This chapter covers the introduction to packet classification. Problems for packet classification, objectives to overcome the problem involved in packet classification, motivation to do the project on packet classification and also the organization of the project. The development of the internet grows for every year, because of the easy access of the internet. The gain of the internet can be obtained through the smartphones, […]
A New Algorithm to Enhance Radio Wave Propagation Strength in Dead Spots for Cellular Mobile WiFi Downloads Using Cloud Networks Signal loss is a major problem for cellular wireless devices, resulting in dropped calls and failure in downloading data. Our research uses a combination of different interaction models to provide an easy interface to replace traditional control methods for maintaining signal levels. The lossy WiFi […]
