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

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

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 ....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

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

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:
Secure distance-based localization in the presence of cheating beacon (or anchor) nodes is an important problem in mobile wireless ad hoc and sensor networks. Despite significant research efforts in this direction, some fundamental questions still remain unaddressed: In the presence of cheating beacon nodes, what are the necessary and sufficient conditions to guarantee a bounded error during a two-dimensional distance-based location estimation? Under these necessary and sufficient co ....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

INTRODUCTION
Sensor networks are applied to various fields ranging from special application fields such as wild environment monitoring, industrial machine measurement and military purpose measurement to daily application fields such as fire monitoring and pollution monitoring. A wireless sensor network is a wire and wireless network, which consists of several sensor nodes deployed in a certain field.
A sensor node should have computation, sensing and wireless communication functions. A wireless sensor network limit ....etc
