CHAPTER 1
INTRODUCTION
A wireless sensor network is a distributed collection of a large number of sensor nodes, which are deployed either inside or very close to the phenomenon. The position of these sensor nodes need not be pre-determined and this allows the random deployment in various applications. Other factor which comes into the focus is that sensor network protocols and algorithms must incorporate self organizing capabilities. Wireless sensor networks are collections of distributed nodes which are capable of ....etc

Abstract-

Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipate low power for low-voltage DCM ....etc

INTRODUCTION
The ocean covers some 70% of our planet and is a rich fund of information on global health, climate change, and resource degradation. Studying marine ecosystems, ensuring port security, and monitoring oil pipelines and leaks of hazardous materials in transit are some of the specific reasons for profiling the concentration and distribution of substances in the ocean.
Considerable research has been conducted to develop and assess methods of sensing the ocean on spatial and temporal scales ranging fr ....etc

Abstract
In this letter, we analyze a class of Opportunistic Power Allocation (OPA) and sensor selection schemes for parameter estimation in wireless sensor networks. In all cases, only sensors experiencing favorable conditions participate in the estimation process by adjusting their transmit power on the basis of local Channel State Information (CSI) and Residual Energy Information. We address a number of classical problems: the minimization of distortion and transmit power, or the enhancement of network lifetime. Furthermore, we derive an ....etc

Wireless distributed microsensor systems will enable fault tolerant monitoring and control of a variety of applications. Due to the large number of microsensor nodes that may be deployed and the long required system lifetimes, replacing the battery is not an option. Sensor systems must utilize the minimal
possible energy while operating over a wide range of operating scenarios. This paper presents an overview of the key technologies required for low-energy distributed microsensors. These include power aware computation/communication component ....etc
