Underwater wireless communications can enable
many scientific, environmental, commercial,
safety, and military applications. Wireless signal
transmission is also crucial to remotely control
instruments in ocean observatories and to enable
coordination of swarms of autonomous underwater
vehicles and robots, which will play the role
of mobile nodes in future ocean observation networks
by virtue of their flexibility and reconfigurability.
To make underwater applications
viable, efficient communication protocols among
underwater devices, ....etc

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

Impact of Node Mobility on Routing Protocols for Wireless Sensor Networks
G. Santhosh Kumar, M.V. Vinu Paul and K. Poulose Jacob
Abstract”
1
Wireless sensor networks monitor their
surrounding environment for the occurrence of some
anticipated phenomenon. Most of the research related to
sensor networks considers the static deployment of sensor
nodes. Mobility of sensor node can be considered as an
extra dimension of complexity, which poses interesting
and challenging problems. Node mobility is a very
important aspect in the des ....etc

Abstract
An Ad-Hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any evolving network infrastructure or centralized administration. Due to the limitations of the wireless environment it may be necessary for one mobile node to enlist the need of other hosts in forwarding a packet to its destination. Thus multiple network hops may be needed for one node to exchange data with another across the network. For this purpose a routing protocol is used to discover routes between these nodes ....etc

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

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

Abstract
A Mobile Ad-Hoc Network (MANET) is a decentralized network of autonomous mobile nodes able to communicate with each other over wireless links. Due to the mobility of the nodes, the topology of the network may rapidly be changing, making it impossible to use conventional routing tables maintained at fixed points (routers). Instead, each node is required to determine the best route to a given destination node by itself. Given their dynamic nature, route discovery in a MANET differs significantly from the more or less static routes in w ....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

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
