Abstract-The current satellite communication systems generally use TDMA signal multiplexing method to improve the frequency efficiency. The system described in this paper has build a signal monitoring platform of TDMA satellite communication system by using general-purpose instruments, the platform has a flexible structure, strong real-time and high levels intelligent. Instead of the traditional monitoring method which uses the communication quality of the entire channel to replace the quality...
Abstract:One of the revolutionary and newest web design trend developing at this time is responsive web design. We have seen last couple of years the growth of handheld devices like smartphone, tablet and other gadgets in.According to research and statistics sales of tablet and smartphone is take over desktop and notebook in 2012, this growth is continue through next some years. increasing more consumers adopt mobile internet technologies in the coming years, those increase people are consume...
Performance Analysis of 802.16 (WiMax) NetworksAbstractThe selection of an appropriate routing protocol is a key issue when designing a scalable and efficient wireless networks. In this paper, we investigate different routing protocols and evaluate their performances on 802.16 WiMAX networks. A comparison between 802.16 and 802.11 ad hoc networks results is presented as well.IntroductionWireless networks play an important role in modern era for transmitting data with minimal overhead and...
Windows NT New Technology 3.1 was introduced one July 27th, on 1993 Windows History Microsoft, 2008. This system was mainly based for business applications, and for employ one servers. The hand purpose of the newer version was to unify Windows 3.1 and Windows NT. There were has few improvements one this version, the most significant being that Windows NT 3.1 was the first operating system that was fully 32 - compatible bit. It also introduced the new NTFS (New Technology File System) that...
CHAPTER 44.1 INTRODUCTION Due to the large number of sensors in WSN and limited communication range, data fusion is employed in order to reduce the traffic load from all the sensors to the base station. Even though this data collection and processing architecture drastically relieves the communication burden on the network, the nodes conducting data fusion are now vulnerable to malicious attacks. If a data fusion node is compromised, it can send bogus data to the base station; the base station...
Effective technology is essential for small businesses looking to increase the productivity of their people and business. Introducing technology such as a computer networks can help them to stay competitive by increasing productivity and by reducing hardware costs. Even simple networks make sharing information and resources easier, provide better security and enable easy backup facilities for any small businesses. One of the primary challenges small business owners face is to get the right...
Grid is a distributed computing architecture that integrates a large number of data and computing resources into a single virtual data management system. A Computational Grid is a natural extension of the former cluster computer where large computing tasks have to be computed at distributed computing resources. A safe registration and communication is essential in Computational Grid networks. This paper reports a secure tunnelling protocol which enhances the quality of Point-to-Point...
IntroductionObjective History of LAN and WAN which is the topic that chosen by me. The reason I choose this topic it is because nowadays people use to communicate with each other by using Internet rather than others traditional way. Some of them not really know what is it and what is the most common network are they using this recently. By doing this assignment, it allow me to get more information about the LAN and WAN and also the information of the connection between it. Here, in this...
Data communication is a combination of computer technology and communication technology. To transfer information between two media from different place we need transmissions channels, according to the different transmission media, there are wired data communications and wireless data communications points. But they are all through the transmission channel will link up with computer data terminal, leaving the data terminals in different locations to achieve software, hardware and information...
In this paper, we have described a redesign methodology for an existing network in the educational system of 6-9 levels in the State of Kuwait, through servers' consolidation. Our detailed study about the existing network showed that the existing servers are under-utilized by more than 44%, thereby increasing the tasks execution delay and maintenance cost. Our redesign methodology operates offline by taking a snapshot of the existing network topology with its clients, servers and their...
