Li-Fi (Light Fidelity)-The future technology in Wireless communication pdf full ppt

Li-Fi (Light Fidelity)-The future technology In Wireless communication pdf full abstract presentation paper journal ppt
Abstract:Li-Fi stands for Light-Fidelity. Li-Fi technology,proposed by the German physicist - Harald Haas, provides transmission of data through illumination by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. This paper focuses on developing a Li-Fi based system and analyzes its performance with respect to existing technology. Wi-Fi is great for general wireless coverage within buildings, whereas Li-Fi is ideal for high density wireless data coverage in confined area and for relieving radio interference issues. Li-Fi provides better bandwidth, efficiency, availability and security than Wi-Fi and has already achieved blisteringly high speed in the lab. By leveraging the low-cost nature of LEDs and lighting units there are many opportunities to exploit this medium, from public internet access through street lamps to auto-piloted cars that communicate through their headlights. Haas envisions a future where data for laptops, smart phones, and tablets will be transmitted through the light in a room. Keywords—Li-Fi, Wi-Fi, high-brightness LED, photodiode,wireless communication.

Low-Power Wireless Sensor Nodes Ubiquitous Long-Term Biomedical Signal Monitoring paper full journal ppt

Low-Power Wireless Sensor Nodes for Ubiquitous Long-Term Biomedical Signal Monitoring paper full journal ppt
Abstract: In the past few years, the use of wireless sensor nodes for remote health care monitoring has been advocated as an attractive alternative to the traditional hospital-centric health care system from both the economic perspective and the patient comfort viewpoint. The semiconductor industry plays a crucial role in making the changes in the health care system a reality. User acceptance of remote health monitoring systems depends on their comfort level, among other factors. The comfort level directly translates to the form factor, which is ultimately defined by the battery size and system power consumption. This article introduces low-power wireless sensor nodes for biomedical applications that are capable of operating autonomously or on very small batteries. In particular, we take a closer look at component-level power optimizations for the radio and the digital signal processing core as well as the trade-off between radio power consumption and on-node processing. We also provide a system-level model for WSNs that helps in guiding the power optimization process with respect to various trade-offs.

Cross-Layer Optimized MAC to Support Multihop QoS Routing for Wireless Sensor Networks

Cross-Layer Optimized MAC to Support Multihop QoS Routing for Wireless Sensor Networks
Abstract—This paper presents an efficient hybrid mediumaccess control (HMAC) protocol with an embedded cross-layer optimization solution to provide routing-layer coarse-grained end to-end quality-of-service (QoS) support for latency-sensitive traffic flows. A novel channel-reservation technique is proposed to significantly reduce the end-to-end delay for delay-sensitive traffic flows by allowing packets to go through multiple hops within a single medium-access control (MAC) frame and by also giving them higher priority channel access to reduce possible queuing delay. Our proposed protocol (HMAC) combines energy-efficient features of the existing contention-based and time-division multipleaccess (TDMA)-based MAC protocols and adopts a short frame structure to expedite packet delivery. Simulation results in ns-2 show that HMAC achieves significant performance improvements in energy consumption, latency, and throughput over existing MAC protocols.

Index Terms—End-to-end latency, energy efficiency, hybrid medium-access control (HMAC), latency-sensitive traffic, quality of service (QoS).

Security in Wireless Sensor Networks using Frequency Hopping paper full

Security in Wireless Sensor Networks using Frequency Hopping
Abstract: A Wireless Sensor Network (WSN) is a collection of thousands of tiny sensor nodes having the capability of wireless communication, limited computation and sensing. These networks are vulnerable to internal and external attacks due to the lack of tamper-resistant packaging and the insecure nature of  wireless communication channels. Since most of the existing routing protocols are application specific and hence do not satisfy the security constraints of wireless sensor networks. Whenever any device comes within the frequency range can get the access to the transmitting data and may affect the transmission. In this paper, we simulated the concept of frequency hopping and proved it a better approach to provide security in WSN.

General Terms: Wireless Sensor Networks, Security, Frequency Hopping.

Design on dielectric Resonator chip antennas for wave wireless applications ieee paper ppt

This Paper is Submitted by Kiran.P (Osmania University)
Paper Presentation on Design & studies on dielectric Resonator On-chip antennas for Millimeter wave wireless applications ( Paper Presentation )
Abstract:Dielectric resonator antenna systems are more realistic antenna system for VLSI Chips due to its simplicity in the integration with other system and monolithic fabrication. DRAs have attracted the antenna designers in microwave and millimeter wave band due to its features like high radiation efficiency, light weight, small size, and low profile, low temperature coefficient of frequency, zero conductor losses and suitable scale in microwave band. DRs of low loss dielectric material, having dielectric constant as 10 < Er < 100 are ideally suitable for antenna applications. When a dielectric resonator is not entirely enclosed by a conducting boundary, it can radiate, and so it becomes an antenna, named Dielectric resonator antenna (DRA).As compared to microstrip antenna, DRAs have much wider impedance bandwidth and they don't support surface waves. In this paper we studied the cylindrical Dielectric resonator antenna configuration along with co-planar waveguide on a semiconductor substrate for millimeter wave wireless application (60GHz).

Keywords- Dielectric resonator antenna, millimeter wave, coplanar waveguide

Long Term Evolution (LTE) - 4g Technology Paper Presentation full

Seminar Papers Presentations IEEE topics abstract Full on Long Term Evolution (LTE) (Seminar Paper Presentations)
Abstract: Long Term Evolution (LTE) is the project name of a new high performance air interface for cellular mobile communication systems.It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. Where the current generation of mobile telecommunication networks are collectively known as 3G, LTE is marketed as 4G. LTE is a standard for wireless data communications technology and an evolution of the GSM/UMTS standards .
LTE, short for Long Term Evolution, is considered by many to be the obvious successor to the current generation of UMTS 3G technology, which is based upon WCDMA, HSDPA, HSUPA, and HSPA. LTE is not a replacement for UMTS in the way that UMTS was a replacement for GSM, but rather an update to the UMTS technology that will enable it to provide significantly faster data rates for both uploading and downloading. Verizon Wireless in the U.S., which is partly owned by Vodafone, has already said that it will support LTE as its 4G technology of choice, abandoning its current CDMA based network.

Worldwide Interoperability for Microwave Access Paper Presentation

Seminar Papers Pharmacy Presentations technical IEEE ppts topics abstract on Worldwide Interoperability for Microwave Access (Seminar Paper Presentations)
Abstract:The two driving forces of modern Internet are broadband, and wireless. The WiMax standard combines the two, delivering high-speed broadband Internet access over a wireless connection. The main problems with broadband access are that it is pretty expensive and it doesn't reach all areas. The main problem with WiFi access is that hot spots are very small, so coverage is sparse.

Here comes the technology of Wi-MAX, acronym for Worldwide Interoperability for Microwave Access and goes by and it also goes by the IEEE name 802.16. This technology would provide high speed of Broadband service, wireless access, and most importantly wide coverage area unlike the Wi-Fi. Because it can be used over relatively long distances, it is an effective "last mile" solution for delivering broadband to the home, and for creating wireless "hot spots" in places like airports, college campuses, and small communities.

Seminar Papers Pharmacy Presentations technical IEEE ppts topics abstract on Wireless Charging Of Mobile Phones Using Micro Waves (Seminar Paper Presentations)
Abstract:With mobile phones becoming a basic part of life, the recharging of mobile phone batteries has always been a problem . The mobile phones vary in their talk time and battery stand by according to their manufacturer and batteries. All these phones irrespective of their manufacturer and batteries have to be put to recharge after the battery has drained out. The main objective of their manufacturer and battery make. In this paper a new proposal has been made so as to make the recharging of the mobile phones is done automatically as you talk in your mobile phone! This is done by use of microwaves. The microwave signal is transmitted from the transmitter along with the message signal using special kind of antennas called slotted wave guide antenna at a frequency is 2.45GHz. There are minimal additions, which have to be made in the mobile handsets, which are the addition of a sensor, a “rectenna” and a filter. With the above setup, the need for separate chargers for mobile phones is eliminated and makes charging universal . Thus the more you talk, the mobile phones is eliminated and makes charging universal. Thus the more you talk, the more is your mobile phone charged! With this proposal the manufacturers would be able to remove the talk time and battery stand by from their phone specifications!

Seminar Papers Pharmacy Presentations technical IEEE ppts topics abstract on Hi-Fi Audio Technology(Seminar Paper Presentations)
Abstract: This paper presents a sufficiently low bit rate Hi-Fi audio coding technique with low computation designed for transmitting real-time high-quality audio signal over wireless channel. This technique applies wavelet packet transform to decompose audio signal into subbands to eliminate redundant data using spectral and temporal masking properties. The encoded audio data is framed with some critical field is protected by channel coding to improve noise immunity when frames are transmitted wirelessly. Experimental results show that transparent CD-audio quality can be achieved at 80kbps encoding bit rate. Moreover, the proposed technique still offers near CD-audio quality when frames are transmitted over AWGN channel with BER below 10-5. These encouraging results clearly exhibit the superior features of our technique compared to others such as Ogg/Vorbis and MP3, which are ubiquitously employed nowadays.

Seminar Papers Pharmacy Presentations technical IEEE topics Abstract on WIMAX (Seminar Paper Presentations)
Abstract: WiMax has helped to push the wireless communication scenario into hyperdrive.For many years cables ruled the world. Optical fibers played a dominant role for its higher bit rates and faster transmission. But the installation of cables caused a greater difficulty and thus led to wireless access. The foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having coverage area of 91mts. No doubt, introduction of Wi-Fi wireless networks has proved a revolutionary solution to “last mile” problem.However, the standard's original limitations for data exchange rate and range, number of channels, high cost of the infrastructure have not yet made it possible for Wi-Fi to become a total threat to cellular networks on the one hand, and hard-wire networks, on the other. But the mans continuous quest for even better technology despite the substantial advantages of present technologies led to the introduction of new, more up-to-date standards for data exchange rate i.e., WiMAX.

Abstract
: Incorporating the environment sensing capability of wireless sensor networks into video based surveillance systems can pro-vide advanced services at a lower cost than traditional surveillance systems .The inte-grated mobile surveillance and wireless sen-sor system (iMouse)use static and mobile wireless sensors to detect and then analyze unusual events in the environment.
The remarkable advances of micro sensing, micro electromechanical sys-tem (MEMS) and wireless communication technologies have promoted the develop-ment of wireless sensor networks .A WSN consists of many sensor nodes densely dep-loyed in a field, each able to collect envi-ronmental information and together able to support multihop ad hoc routing.
Traditional surveillance systems typi-cally collect a large volume of videos from wallboard cameras, which require huge computation or manpower to analyze. Inte-gration WSN’s sensing capability into these systems can reduce such overhead while providing more advance, context –rich ser-vices. For example, in a security application, when the system detects an intruder, it can conduct in depth analyses to identify the possible source.
