In the realm of Internet of Things (IoT), wireless sensor networks (WSNs) have been the
subject of ongoing research into the use of energy harvesting to capture ambient energy, and …

Wireless sensor networks (WSNs) are used to collect large amounts of data over a wide
area. However, the sensor nodes used in WSNs have a short lifespan because they are …

… scheme; Ikjune Yoon and Hyeok Kim designed and performed the experiments; Ikjune Yoon
and Dong Kun Noh analyzed the data; and the manuscript was written by Ikjune Yoon and …

This paper proposes a reliable wildfire monitoring system based on a wireless sensor
network (WSN) sparsely deployed in adverse conditions. The physical environment under …

Research on data routing strategies for wireless sensor networks (WSNs) has largely focused
on energy efficiency. However rapid advances in WSNs require routing protocols which …

In solar-powered wireless sensor networks (SP-WSNs), sensor nodes can continuously
harvest energy to relieve the energy constraint problem in battery-powered WSNs. With the …

Wireless rechargeable sensor nodes can collect additional data, which leads to an increase
in the precision of data analysis, when enough harvested energy is acquired. However, …

In this paper, we propose the algorithms which determine 1) the efficient anchor-node visiting
route of mobile sink in terms of energy supply and 2) the efficient energy amount to be …

By utilizing mobile sinks in wireless sensor networks (WSNs), WSNs can be deployed in
more challenging environments that cannot connect with the Internet, such as those that are …

In wireless sensor networks, a node that increases its sensing rate to gather more data
consumes more energy. Consequently, it will be exhausted earlier than other nodes. In this article…
