Integrating Sensor Networks and Grid Computing pdf full abstract presentation paper journal ppt
Abstract: Integrating sensor networks and grid computing in sensor-grid computing is like giving ‘eyes’ and ‘ears’ to the computational grid. Real-time information about phenomena in the physical world can be processed, modelled, correlated and mined to permit on-the-fly decisions and actions to be taken on a large scale. Examples include environment monitoring with prediction and early warning of natural disasters, and missile detection, tracking and interception. We describe some early work in sensor-grid computing, and discuss the research challenges that need to be overcome before such a vision can become reality, such as web services and service discovery, interconnection and networking, coordinated quality of service (QoS) mechanisms, robust and scalable distributed algorithms and efficient querying.

Satellite Encryption full paper download

Abstract: The main aim of this paper is to create awareness towards satellite encryption. In an age of explosive worldwide growth of electronic data storage and satellite communications, many vital national interests required the effective protection of information. Especially when used in coordination with other tools for information security, encryption in all of its applications, including data confidentiality, data integrity, and user authentication, is a most powerful tool for protecting information. Encryption is a powerful tool that can be used to protect information stored and communicated in digital form via satellite. Encryption can help to assure confidentiality of data; to detect unauthorized alterations in data and thereby help to maintain its integrity; and, to authenticate the asserted identity of an individual or a computer system. Encryption can be used in a number of applications to secure voice, data communications and stored information.

Three-Tier Framework for Intruder Information Sharing Sensor Networks seminar paper

Paper Presentation on A Three-Tier Framework for Intruder Information Sharing in Sensor Networks ( Paper Presentation )
Abstract:In sensor networks, an intruder (i.e., compromised node) identified and isolated in one place can be relocated and/or duplicated to other places to continue attacks; hence, detection and isolation of the same intruder or its clones may have to be conducted repeatedly, wasting scarce network resources.
Therefore, once an intruder is identified, it should be known to all innocent nodes such that the intruder or its clones can be recognized when appearing elsewhere. However, secure, efficient and scalable sharing of intruder information remains a challenging and unsolved problem. To address this problem, we propose a three-tier framework, consisting of a verifiable intruder reporting (VIR) scheme, a quorum based caching (QBC) scheme for efficiently propagating intruder reports to the whole network, and a collaborative Bloom Filter (CBF) scheme for handling intruder information locally. Extensive analysis and evaluations are also conducted to verify the efficiency and scalability of the proposed framework.

Designing an Adaptive Acoustic Modem for Underwater Sensor Networks seminar paper

Paper Presentations ppts topic Designing an Adaptive Acoustic Modem for Underwater Sensor Networks (Seminar Paper Presentations)
Abstract:There is a growing interest in using underwater networked systems for oceanographic applications. These networks often rely on acoustic communication, which poses a number of challenges for reliable data transmission. The underwater acoustic channel is highly variable; each link can experience vastly different conditions, which change according to environmental factors as well as the locations of the communicating nodes. This makes it difficult to ensure reliable communication. Furthermore, due to the high transmit power, the energy consumed in transmitting data is substantial, which is exacerbated at lower data rates. The main challenge that we address in this article is how to build a system that provides reliable and energy efficient communication in underwater sensor networks. To this end, we propose an adaptive underwater acoustic modem which changes its parameters according to the situation. We present the design of such a modem and provide supporting results from simulations and experiments.

Index Terms—Acoustic modem, underwater sensor networks, wireless communication.

REDTACTON -A Human Area Network Technology abstract paper

Seminar Papers Pharmacy Presentations technical IEEE ppts topics abstract on REDTACTON- A Human Area Networking Technology (Seminar Paper Presentations)
Abstract:
This paper gives you a detailed explanation of the most advanced and the newly introduced networking technology which is still under development.That is the REDTACTON. RedTacton is a Human Area Networking technology, which is under development.It uses the surface of the human body as a safe, high speed network transmission path. It is completely distinct from wireless and infrared technologies as it uses the minute electric field emitted on the surface of the human body.A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. RedTacton works through shoes and clothing as well. When the physical contact gets separated, the communication is ended.This type of networking technology is a very advanced and a very secure one.The redtacton may prove to be a best way for the transmission of highly confidential issues and data.The following paper will give you beter understanding and explanation.

Abstract: Recently, demand for high-speed Internet access is rapidly increasing and a lot of people enjoy broadband wired Internet access services using ADSL ( Asymmetric Digital Subscriber Line)or cable modems at home.

On the other hand, the cellular phone is getting very popular and users enjoy its location-free and wire-free services. The cellular phone also enables people; to connect their laptop computers; to the Internet in location-free and wire-free manners. However,present cellular systems like GSM (Global System for Mobile communications) can provide much lower data rates compared with those provided by the wired access systems, over a few Mbps(Mega bit per second. Even in the next generation cellular system, UMTS ( Universal Mobile Telecommunications System), the maximum data rate of its initial service is limited up to 384kbps therefore even UMTS cannot satisfy users’ expectation of high-speed wireless Internet access.

Optical Network Architecture Abstract download Seminar paper

Seminar Paper Pharmacy Presentations technical IEEE ppt topics Abstract papers on Optical network abstract download Paper Presentation
Abstract: One of the major issues in the networking industry today is tremendous demand for more and more bandwidth. However, with the development of optical networks and the use of Dense Wavelength Division Multiplexing (DWDM) technology, a new and probably, a very crucial milestone is being reached in network evolution. The existing SONET/SDH network architecture is best suited for voice traffic rather than today’s high-speed data traffic. To upgrade the system to handle this kind of traffic is very expensive and hence the need for the development of an intelligent all-optical network. Such a network will bring intelligence and scalability to the optical domain by combining the intelligence and functional capability of SONET/SDH, the tremendous bandwidth of DWDM and innovative networking software to spawn a variety of optical transport, switching and management related products. This paper deals with optical network architecture and explains virtual topology along with optical layer and higher layer interface.

Socket Interface paper presentation | Application Interface seminar report full

Paper Pharmacy Presentations technical seminar ppts Abstract papers on Socket Interface using TCP/IP Protocols
Abstract:
We must have an interface between the application programs and the protocol software in order to use network facilities. My seminar is on a model of an interface between application programs and TCP/IP protocols. The standard of TCP/IP protocol do not specify exactly how application programs interact with the protocol software. Thus the interface architecture is not standardized; its design lies outside of scope of the protocol suite. It is further should be noticed that it is inappropriate to tie the protocols to a particular interface because no single interface architecture works well on all systems. In particular, because protocol software resides in a computer’s operating system, interface details depend on the operating system.

In spite of lack of standards, a programmer must know about the such interfaces to be able to use TCP/IP. Although I have chosen UNIX operating system in order to explain the model, it has widely accepted and is used in many systems.
