Wireless networks have displaced the well established and widely deployed wired
communication networks of the past. Tetherless access and new services offered to mobile …

Wireless sensor networks (WSNs) are effective for locating and tracking people and objects
in various industrial environments. Since energy consumption is critical to prolonging the …

Locating sensor nodes in an ad hoc wireless sensor network (WSN) is a challenging task. In
general, the network nodes are not synchronised and the internal delays within the nodes …

In line with recent research efforts made to conceive energy saving protocols and algorithms
and power sensitive network architectures, in this paper we propose a transmission strategy …

Study of pipeline networks which are used to transfer gas and oil from the production sites to
consumers has widened all over the globe. On the other hand, there is a colossal loss of …

A hybrid anchor-free localisation scheme for multihop wireless sensor networks is
presented. First, a relatively dense group of nodes is selected as a base, which are localised …

This paper presents a framework for optimizing the trade-off between energy consumption
and localization accuracy in hybrid localization systems combining Received Signal …

Sensor Networks have been heralded as one of 21 most enabling technologies for 21st
century by Business Week. In recent times wireless sensor networks have received …

This paper considers a two-tier hierarchical heterogeneous wireless sensor network using
the concept of clustering. The network has two type of nodes: regular sensor nodes …

Today, localization of nodes in Wireless Sensor Networks (WSNs) is a challenging problem.
Especially, it is almost impossible to guarantee that one algorithm giving optimal results for …
