Wireless sensor networks (WSN) consist of a set of sensors and collection sinks that gather
and analyze environmental conditions. Spurred by the growing need for data collection and …

A major concern in wireless sensor network (WSN) is how to maximize the network lifetime
while maintaining the coverage requirement. Since the energy of sensor node is limited, the …

In this article, the coverage reliability of wireless sensor network is evaluated from a new
perspective. Based on the DS evidence theory, we define the concept of belief degree of …

To solve the problem of unbalanced loads and the short network lifetime of heterogeneous
wireless sensor networks, this paper proposes a node‐selection algorithm based on energy …

The reliability of k-barrier coverage for wireless sensor networks is evaluated in this article.
We construct a two-dimensional k-within-consecutive-r× s-out-of-m× n: F system to describe …

A sophisticated method for node deployment can efficiently reduce the energy consumption
of a Wireless Sensor Network (WSN) and prolong the corresponding network lifetime …

Abstract Wireless Sensor Networks (WSNs) has become one the promising research theme
due to the availability of wide range of applications useful for almost each and every area of …

In order to monitor the gas leakage, the gas sensors are deployed conventionally in
chemical industry park, with little considerations given to the gas characteristics and weather …

In dense IoT deployments of wireless sensor networks (WSNs), sensor placement,
coverage, connectivity, and energy constraints determine the overall network lifetime. In …

Technological advances have led to the emergence of wireless sensor nodes in wireless
networks. Sensor nodes are usually battery powered and hence have strict energy …
