Lower Energy Consumption

ABSTRACT This research demonstrates that the optimization for lower energy consumption leads to cross layer design from the two ends namely physical layer and the application layer. This optimization for quality of service requirements demands integration of multiple OSI layers (Open Systems Interconnect) Beginning from the physical layer the probability of successful radio packet delivery is first explored. This probability along with network energy consumption is traded off to let CTP-SN (Cooperative Transmission Protocol for Sensor Networks) demonstrate that sensor […]

Voip Future Telephony| Information Systems Dissertations

The Impact of VoIP on the Future of Telephony With the dawning of a new age of pervasive computing, there is a greater requirement for the exchange of data to be made possible between computing assets that are connected to a network. Interactions require an exchange of various multimedia formats as well as the provision of enhanced services including instant messaging and presence management. There is, therefore, a need for a converged network that is capable of carrying both voice […]

Piezoelectric Energy Home Analysis

1.0 Introduction In Malaysia, each house using electricity at Tenaga Nasional Berhad (TNB). With the use of electricity, the family in each house to do the activities and generate electrical appliances such as air conditioners, refrigerators, washing machines and others. Basically when using a lot of electricity, home users should pay a lot of bills. Some homes also have alternative energy like solar, water and wind, but it has disadvantages because of the use of solar energy they generate during […]

Robot Design

Robot is a kind of automatic machine, which has particularly a series of similar competences as human-being, such as sensing capability, planning capability, moving capability and so on. The word ‘Robot’ was referred by Czech writer Karel ?apek in his play R.U.R (Rossum’s Universal Robots), which was published in 1920. [1] Moreover, the word robotics, which describes this kind of field of study, was referred accidentally by the science fiction writer Isaac Asimov. In his science fiction, all the robots […]

Improvement of Building Management System to Save Energy

Improvement of Building Management System to Save Energy 1. Introduction of BMS Building Management System (BMS) is to control and monitor building services systems in an efficient way by centralizing the control of individual systems ( 1.1). The systems include HVAC, Fire Services Lift, Escalator, Lighting, Electrical Distribution, Steam & Hot Water, and Plumbing & Drainage. The main function of BMS is centralized control & monitoring and fault management. So it has another name call Central Control and Monitoring System […]

The Art and Science

Introduction Electronics is the art and science of getting electrons to move in the way we want to do useful work. An electron is a sub-atomic particle that carries a charge of energy. Each electron is so small that it can carry only a tiny bit of energy. The charge of electrons is measured in coulombs. One coulomb is the charge carried by 6,250,000,000,000,000,000 electrons. That’s 6.25 X 1018 electrons for you math whizzes. Every good electronics text begins with […]

Broadband Network in Malaysia

The intention of this final year project is to study about the high speed wireless broadband network in Malaysia. This project consists of two major parts; which are investigating of problems of service in wireless broadband network and improvement and enhancement in wireless broadband network in Malaysia. For each part, is further divided into the making of comparison between wireless broadband providers in Malaysia. The research part requires the study about the improvement and enhancement about the wireless broadband technology […]

Gps Tracking System

GPS Tracking (a) Tracking Global Positioning System (GPS) is a global satellite navigation system that used a network of satellites into orbit by the U. S. Department of Defense. GPS satellites circle the earth twice a day for a very precise orbit and transmit signal information to earth. GPS receivers for the information and use triangulation to calculate the user’s exact location. (b) the accuracy of the tracking method GPS receivers are extremely accurate, because they are parallel to the […]

What does Vehicle Tracking System Mean?

What is vehicle tracking system? Vehicle tracking system is to track the vehicle’s location and it’s kind of electronic device and need to install in the vehicle. There are many kind of vehicle tracking system like GPS, RFID, fleet tracking system, VTU, satellite tracking, etc. Among them, I would like to introduce the GPS vehicle tracking system, RFID vehicle tracking system and VTU vehicle tracking unit. There are two tracking system, active and passive. Passive tracking is only record the […]

Ad Hoc Network

Ad hoc network Abstract A mobile ad hoc network (MANET) is consisting of wireless mobile nodes. The communication of these mobile nodes is carried out without any centralized control. Routing is a critical issue in MANET. The focus of this thesis is on the performance of routing protocols. We compare three routing protocols in MANET i.e. AODV, DSR and OLSR. OPNET is the simulation tool. These routing protocols performance are analyzed by three important metrics: delay, network load and throughput. […]

Reliable Data Transmission over Wireless Network

CHAPTER – 1 INTRODUCTION TO THE STUDY 1.1 INTRODUCTION TO THE PROBLEM This report specifies the wireless secured communication in an enterprise when there is increasing demand of ubiquitous multimedia data services, future wireless networks are expected to provide services with wider coverage area, reliable and higher data throughput with security. To acheive these goals, wider bandwith at higher carrier frequency above 2GHz is forseen to be needed. Since the radio propogation in these frequency band is more velnurable to […]

Video Transmission in Wireless Mesh Networks

1. Introduction: Video transmission in Wireless Mesh Networks Recently there has been research interest in supporting Wireless Mesh Networks (WMN). Wireless Mesh Networks provides cheap and efficient network connectivity in a large region. There are number of significant advantages by using multipath for video communications, such as load balancing, potentially higher video bit rate and improved error resilience (Vishnu Navda). Video applications development has been impulsive. For provide round-the-clock surveillance of critical areas of their communities municipalities now organize video […]

Private Branch Exchange System

INTRODUCTION 1.0 INTRODUCTION Private branch exchange system (PBXs) operates as a connection within private organizations usually a business. Because they incorporate telephones, the general term “extension” is used to refer to any end point on the branch. The PBX handles calls between these extensions. The primary advantage of PBXs was cost savings on internal phone calls: handling the circuit switching locally reduced charges for local phone services. The private branch exchange (PBX) provides internal station-to-station communications for a well-defined set […]
