For group communication, one of the most efficient methods is multicasting. Over a dynamic topology it is difficult to implement group membership management and multicast package forwarding. So a new algorithm in Economic Spatial Group Multicast protocol(ESGMP) which uses a virtual-zone-based structure which was proposed to provide multicasting environment, in which nodes are divided into Zones. A multicast tree is constructed and an cost efficient multicast packet forwarding procedure is obt...
Project essentially demonstrates a Small Office / Home Office network design architecture with minimal functionalities of printer and a server which can be used on a very small scale framework. It shows us the cost effectiveness of any equipment in a network. Table of Contents Abstract We plan to implement a SoHo network in a school campus where all the basic amenities of networking are accessible like a FTP server, print server, DHCP server, etc. Our main focus would be on security of the en...
The Clifford Stoll was promoted honeypot system in 1990 to monitor attacker's threats, he introduced this honeypot network for tracing attacker sources information by detecting attacker accessibility environment. The Lance Spitzner who introduced techniques in 1999 to build efficient Honeypots for the development of Honeynet project., I he introduced the concepts and architectures for Honeypot which gives information on Honeypot terms and notions 2.3 Types of Honey pots There are different ty...

Task 1 (5.b) Importance and Effectiveness of Legal Regulation in E-Commerce. Introduction The term 'Electronic commerce'(E-commerce) has been defined by Kalakota and Whinston as having many perspectives - communications, business, service and on-line. Electronic commerce is also defined as, any action undertaken by a business which requires a financial transaction to be carried out over a network such as the Internet. Electronic Data Interchange (EDI) is a form of electronic commerce concerne...
Memory stores, instructions and data. Memory is of two types, primary memory and secondary memory. Instruction or data given by input devices is first getting stored in the primary memory. Further user saves processed (executed) data in the secondary memory. Primary memory is temporary and secondary memory is permanent. Primary memory is the main memory of the computer system. It is faster than secondary memory. It directly communicates with CPU. 3.2 Memory Unit Computer uses several types of...
The coder part of the codec and demodulator part of the codec are way too different from each other. Write on some aspects of the difference between bÂÂoth of them. Ans :- Computer data sent over a modem are analog. The analog signals are digitized in the end office by a device called a codec coder - decoder producing a series of 8-bit numbers. The code makes 8000 codec is any technology for compressing and decompressing data.In telecommunications, short for coder/decoder a device that enco...
CHAPTER 1 INTRODUCTION 1.1 Introduction: In a university or in a college exam timetabling is a difficult problem. Exam timetabling should be done three times an academic year in a university. We should consider lots of rules to develop an exam timetable for a particular department such as Computing. In this project "Exam timetabling using constraint satisfaction", we consider Computing department to create a time table by keeping all the constraints in mind. We need to develop user friendly s...
Abstract Cloud computing is on the boom so is the security concerns related to its usage. Researchers and cloud computing services providers are in search of state of the art models to ensure the availability, security and safety of the users' information Cloud computing is the next generation architecture of IT Enterprise. Conventionally, the IT software and infrastructure was under physical, logical and personnel controls. Cloud computing provide an opportunity to share these resources to o...
Low Noise Amplifiers are solitary of the electronic amplifiers which are utilizing to enlarge feeble or extremely feeble signals which are confining by antennas. These amplifiers are the most important element utilize in the radio recipient circuit. It decreases the haphazardness from dissimilar period of in receipt of signal. LNAs are premeditated to comprise especially lavishly gains and especially depleted haphazardness stimulant. This is completed to decrease the overall haphazardness pro...
