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

With innumerable number of road accidents happening everyday, every year due to drunken driving has become an important issue of concern. The life threatening addiction of alcohol has ruined many lives and futures.The device BREATH-O-METER detects and alerts about the level of alcohol consumed by a person. It provides a a non-invasive method of measuring the humanâ„¢s blood alcohol content (BAC).
The first breath analyzer used used chemical oxidation and photometry to determine alcohol concentration. The detectors that followed have conv ....etc

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
