Wireless Sensor Networks

A wireless sensor network consists of large Number Of Nodes.Large number of heterogeneous Sensor devices spread over a large field.They perform Wireless sensing and Data Networking. Group of sensors linked by wireless media to perform distributed sensing tasks
Each node has three components: sensing, processing, and communication. Networked sensors can continue to operate accurately in face of failure of individual sensors.Each sensor node operates autonomously with no central point of control in the network. E ....etc

Problems and solutoions to WiFi security



Hoe it Works?
Basically the working of WiFi is based on transmission process. In this process the data which is going to be transferred has to be transmitted in the form of radio signals, and then the device transmits these signals to antenna which is used for transferring of data. This antenna is which is used for transmission purpose is connected with a wired LAN or DSL. A router is also connected with the device w ....etc

SECURITY RISKS AND SOLUTIONS IN AD-HOC ROUTING PROTOCOLS
Presented By:
Dr.H.B.Kekre
Professor, Thadomal Sahhani Engineering College, Bandra(w), Mumbai,India

ABSTRACT
Mobile Ad-Hoc Networks (MANETs) are becoming
increasingly popular as more and more mobile devices
find their way to the public, besides traditional uses
such as military battlefields and disaster situations they
are being used more and more in every-day situations.
With this increased usage comes the need for making the
networks secure as w ....etc

ABSTRACT
Wi-Fi, which stands for Wireless Fidelity, is a radio technology that networks computers so they connect to each other and to the Internet without wires .Users can share documents and projects, as well as an Internet connection among various computer stations, and easily connect to a broadband Internet connection while traveling. By using a Wi-Fi network, individuals can network desktop computers, laptops and PDAs and share networked peripherals like servers and printers.

Well this is the project that i chose for my final Sem...we need help.....we need some Java coding samples for the routing protocls like DSR ADOV, and Key management protocols.....We still dont have clarity with what we are going to do....we have a week to present our project...please help...i have to give my presentation on 27/3/2010


i have attached the coding details which i collected and the paper(its IEEE paper) please seee if needed..... ....etc

Introduction

Wireless sensor networks are increasingly
prevalent (or at least that was the prevailing thought in 2002)
 Sensors are very resource-limited
(SmartDust)
– Slow communication links (10 kbps)
– Limited computing power (8-bit, 4 MHz)
– Limited memory and storage (512 bytes)
– Limited batter ....etc

Roll No 870090
MCA 4th Semester


Introduction
Bluetooth, or IEEE 802.15, specifications are developed by the Bluetooth SIG,originally established by Ericsson,Toshiba,Motorola,Intel,IBM and Nokia.The latest version is Bluetooth 2.0 with data transfer rate 3Mbps
WiFi is controlled by the WiFi alliance, an industry forum. Its specifications form IEEE 802.11 standards.WiFi comes in various flavors like 802.11a,b,g etc
Both Bluetooth and WiFi a ....etc

Abstract:Network security is a complicated subject, historically only tackled by well trained and experienced experts. However as more and more people become wired an increasing number of people need to understand the basics of security in a networked world in this document we discuss some of the network security issues in TCP/IP.
The Transmission control protocol/Internet protocol (TCP/IP) suite is a very widely used technique that is employed inter connect computing facilities in modern network environments TCP/IP is the language of ....etc

The two most important phenomena impacting telecommunications over the past decade have been explosive parallel growth of both the internet and mobile telephone services. The internet brought the benefits of data communications to the masses with email, the web, and ecommerce; while mobile service has enabled follow-me anywhere/always on telephony. The internet helped accelerate the trend from voice-centric to data-centric networking. Data already exceeds voice traffic and the data share continues to grow. Now these two worlds are converging. ....etc
