A NEW MULTI-PATH AODV ROUTING BASED ON DISTANCE OF
NODES FROM THE NETWORK CENTRE.


Introduction:

END-TO-END packet delay is one of the canonical metrics in Internet Protocol (IP) networks, and is important both from the network operator and application performance points of view. For example the quality of Voice Over IP is directly dependent on delay, and network providers may have Service Level Agreements (SLAs) specifying allowable values of delay statistics across the domains they control. An important component of ....etc

Wireless Sludge Level Monitoring based on Bluetooth Sensing Nodes



I. INTRODUCTION
Sedimentation (settling) is the separation of suspended
particles that are heavier than water. The sedimentation of
particles is based on the gravity force from the differences in
density between particles and the fluid. Secondary
sedimentation tanks are fundamental facilities in activated
wastewater treatment processes. Usually a secondary
sedimentation tank is a cylindrical concrete buildin ....etc

INTRODUCTION

RAIN (also called channel bonding, redundant array of independent nodes, reliable array of independent nodes, or random array of independent nodes) is a cluster of nodes connected in a network topology with multiple interfaces and redundant storage. RAIN is used to increase fault tolerance. It is an implementation of RAID across nodes instead of across disk arrays.
RAIN can provide fully automated data recovery in a local area network (LAN) or wide area network (WAN) even if multiple nodes fail. A browser-based, centralized, s ....etc

Abstract-

We have analyzed the effect of innovations in Nanotechnology on Wireless Sensor Networks (WSN) and have modeled Carbon Nanotube (CNT) and Micro-Electro- Mechanical Systems (MEMS) based sensor nodes. SUGAR library in MATLAB has been used to illustrate the static analysis of deflection, display the structure and to compute the displacement parameters of a cantilever beam subjected to an external force. A WSN (Wireless Sensor Network) model has been programmed using Simulink in MATLAB. We have shown the integrati ....etc

RELIABLE ARRAY OF INDEPENDENT NODES

ABSTRACT

Nowadays the number of people who are using Internet is dramatically increasing. With no hesitation, it can be said that the Internet is indeed the most popular media of communication prevailing in the present world scenario. But many of the users are nowadays facing the problem of failure in maintaining the connection with the cyber world.

The prime reason for the problem is that in the existing technology of connection with the Internet, a client is ....etc

Wireless Sensor Network (WSN) nodes are often deployed in harsh environments where the possibility of permanent and especially intermittent faults due to environmental hazards is significantly increased, while silicon aging effects are also exacerbated. Thus, online and in-field testing is necessary to guarantee correctness of operation. At the same time, online testing of processors integrated in WSN nodes has the requirement of minimum energy consumption, because these devices operate on battery, cannot be connected to any external power supp ....etc

how to set sleep and wakeup for nodes in ns2 in aodv

public:
AODV();
void CLUSTERING();
..
AODV.cc :
void AODV::CLUSTERING(){
if(current_){
while(numberofNodes){
// Selecting clusters
}
}
}
Now we know how the mechanism of ns2 works.so let's get started with sleep nodes.
First of all there is 4 functions in ns2 for turning a node to 'off', 'on', 'sleep', 'idle'. The difference between these are not so big.
As you know the 'off' function turns a node to off but it still broadcasts something based on your protocol.
$ns_ at 7.0 $ ....etc

Scheduling Sleeping Nodes in High Density Cluster based Sensor Nodes (VC++)
ACM Transactions on Mobile Networks and Applications, Volume 10,

Abstract: In order to conserve battery power in very dense sensor networks, some sensor nodes may be put into the sleep state while other sensor nodes remain active for the sensing and communication tasks. In this paper, we study the node sleep scheduling problem in the context of clustered sensor networks. We propose and analyze the Linear Distance-based Scheduling (LDS) technique for sleeping in eac ....etc

Abstract
In sensor networks, nodes commonly rely on each other to route massages to a base station. Although this practice conserves power it can obscure the cause of measurement in a portion of the network. For example, when a base station ceases to receive measurements from a region of nodes it can not immediately determine whether this is because of the destruction of all the nodes in that region or merely the result of the failure of a few nodes bearing much of the routing load. Previous solutions to this problem typically consists of rer ....etc
