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

Seminar on Wireless Sensor Networks is an Intelligent Electronic Devices



Abstract

Automation of electric power distribution in a cost-efficient and reliable manner can be accomplished by complete automation of the load dispatch centers and substations on a large scale. For efficient load balancing among the feed lines, a continuous monitoring of parameters, such as voltage, current in the line, temperature, pressure, and oil level of the transformers is required. Currently, automation is done with th ....etc

Interference-Minimized Multipath Routing with Congestion Control in Wireless Sensor Network for High-Rate Streaming - IEEE TRANSACTIONS ON MOBILE COMPUTING, VOL. 7, NO. 9, glomosim

Abstract—
High-rate streaming in WSN is required for future applications to provide high-quality information of battlefield hot spots. Although recent advances have enabled large-scale WSN to be deployed supported by high-bandwidth backbone network for high-rate streaming, the WSN remains the bottleneck due to the low-rate radios used and the effects of ....etc

Efficient water management is a major concern in many cropping systems in semiarid and arid areas. Distributed in-field sensor-based irrigation systemsoffer a potential solution to support site-specific irrigation management that allows producers to maximize their productivity while saving water. This paper describes details of the design and instrumentation of variable rate irrigation, a wireless sensor network, and software for real-time in-field sensing and control of a site-specific precision linear-move irrigation system. Field conditions ....etc

Abstract.
Heterogeneous wireless sensor network (heterogeneous WSN) consists of sensor nodes with different ability, such as different computing power and sensing range. Compared with homogeneous WSN, deployment and topology control are more complex in heterogeneous WSN. In this paper, a deployment and topology control method is presented for heterogeneous sensor nodes with different communication and sensing range. It is based on the irregular sensor model used to approximate the behavior of sensor nodes. Besides, a cost model is proposed t ....etc
