In a large-scale wireless sensor network, it is often desirable to count the number of nodes in
the network, or the number of nodes that are within communications range of a particular …

Size estimation is very important for a network's proper operation, but it is difficult to estimate
in underwater environment using conventional protocol based techniques. An alternative …

The performance of most array signal processing tasks relies on the presence of correlation
between sensor signals. In a wireless sensor network, where sensor nodes are spread out …

Estimation of the number of nodes in a communication network is very important, particularly
in ad hoc networks. But it is difficult to estimate in underwater wireless sensor networks due …

The problem of combining task performance and routing for the detection of correlated
random fields using multi-hop wireless sensor networks is considered. Under the …

We study the problem of maximizing lifetime in sensor networks that are deployed for
estimating an unknown parameter or process. Sensors take measurements and transport …

In this paper, we study the energy-efficient distributed estimation problem for a wireless
sensor network where a physical phenomena that produces correlated data is sensed by a …

Cardinality estimation of underwater network is somewhat troublesome using terrestrial
node estimation methods due to unique characteristics of underwater environment such as …

This paper explores metrics that capture to what degree packet reception on different links is
correlated. Specifically, it explores metrics that shed light on when and why opportunistic …

Distance estimation is vital for localization and many other applications in wireless sensor
networks (WSNs). Particularly, it is desirable to implement distance estimation as well as …
