Distributed Signal Processing in Sensor Networks

In recent years, the widespread availability of embedded processors and easily accessible wireless networks have resulted in a new sensing concept based on connecting a large number of inexpensive and small sensors in a sensor network. In principle, a sensor network can be highly scalable, cost effective, and robust with respect to individual sensor’s failure. However, there are important theor...

Linear coherent distributed estimation with cluster-based sensor networks

The authors consider distributed estimation using sensor network with coherent multiple access channel model and LMMSE fusion rule. The sensors in the network are divided into a number of clusters. Sensors within the same cluster are allowed to collaborate through an amplification matrix to form a message this then transmitted. They formulate the problem of choosing the amplification matrices a...

Design and evaluation of two distributed methods for sensors placement in Wireless Sensor Networks

Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...
