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

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

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-

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

Accurate, Low-Energy Trajectory Mapping for Mobile Devices


INTRODUCTION
With the proliferation of sensor-equipped smartphones,
the decades-long promise of location-based mobile services
and mobile sensing applications is finally becoming
real. Many location-based applications periodically
probe the device s position sensor to obtain a stream of
position samples, and then process this stream to obtain
a trajectory. Examples include crowd-sourced traffic
and navigation appli ....etc
