Various routing structures have been proposed for the data gathering in wireless sensor
networks, which are supposed to be efficient in terms of energy consumption and delivery …

Sensor nodes are typically battery-powered. As a result, maximizing the network lifetime is
an important optimization objective in the design of a WSN (Wireless Sensor Network). In …

Continuous queries in wireless sensor networks (WSNs) are founded on the premise of
query routing tree structures (denoted as T), which provide sensors with a path to the …

Data collection is a fundamental and important issue in wireless sensor networks (WSNs).
Recent research has shown that using mobile nodes to collect and carry data in WSNs has …

This paper designs and implements a tree-based routing algorithm that allows a user to
gather aggregated information from individual sensor node's readings in a large-scale …

Wireless sensor networks (WSN) consists of tiny autonomous devices called sensors
capable of sensing, processing and transmitting information. Energy consumption, routing …

In sensor networks, overlapping sensed areas result in the collection of partially redundant
data. Interior sensor nodes along a data collection tree can remove redundancies and …

We study the problem of transmitting data from a set of sensors to a base-station where the
data is to be gathered. Each sensor continuously generates data and has to transmit it …
