Connected Sensor Cover: Self-Organization of Sensor Networks for Efficient Query Execution (Java)
IEEE/ACM Transactions on Networking, Vol. 14, No. 1

Abstract:
Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor network can be exploited to reduce the communication cost incurred in execution of such queries. Any reduction in communication cost would result in an efficient use of the battery energy, which is ....etc

Wireless Sensor Networks

Technology Overview


The individual nodes that constitute a wireless sensor network are generally small in size and use power-efficient batteries to extend their operational longevity. Depending on its function, each node has a sensor board that facilitates the detection and measurement of heat, vibrations, air-pressure and magnetic fields (among other things). The motes developed at UC Berkeley are a typical example of such devices. Motes h ....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 deri ....etc

1. Introduction

The advent of integrated circuits, which became possible because of the tremendous progress in semiconductor technology, resulted in the low cost microprocessor. Thus if it is possible to design a low cost sensor which is silicon based then the overall cost of the control system can be reduced .We can have integrated sensors which has electronics and the transduction element together on one silicon chip. This complete system can be called as system-on-chip .The main aim of integrating the electronics and the sensor is to make ....etc
