Wireless sensor networks are the networks consisting of large number of small and tiny sensor nodes. The nodes are supplied with limited power, memory and other resources and perform in-network processing. In this paper, various issues are discussed that actually put the limitations in the well working and the life time of the network. In Wireless sensor network, nodes should consume less power, memory and so data aggregation should be performed. Security is another aspect which should be present in the network. Quality of service, routing, medium access schemes all are considered in designing the protocols.read more

Decentralized Estimation Under Correlated Noise
TL;DR: It is shown that knowledge of noise correlation at the sensors will help to improve the system performance, and that when noise at the fusion center is correlated, even with knowing the correlation structure, the systemperformance degrades.
