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 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 ....etc

As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. Sensor networks have been identified as being useful in a variety of domains to include the battlefield and perimeter defense. So far, much research has focused on making sensor networks feasible and useful, and has not concentrated on security. We present a suite of security building blocks optimized for resource constrained environments and wireless communication. SPINS has two secure building blocks: SNEP and ?TESLA SNEP provides the foll ....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

WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called motes that form an ad-hoc network to transmit this data to a computer that function as a server. The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote. ....etc

Power consumption, physical size, and architecture design of sensor node processors have been the focus of sensor network research in the architecture community. What lies at the foundation for these research is the hardware- level design which determines the boundaries for achievable utility and performance. Architecture design and evaluation, however, cannot be accomplished independent of the applications and software that run on these sensor nodes. On one hand, some researchers have proposed architectures that can cater to a variety of appli ....etc
