Wireless sensor networks form the crux of a wide range of automated applications that are
gaining popularity with every passing day. The journey of wireless sensor networks has …

Several data collection algorithms, which are based on the combination of using mobile
sinks and multiple-hop forwarding, have been proposed to prolong the network lifetime of …

The hotspot problem is one of the primary challenges in the wireless sensor networks
(WSNs) because it isolates the sink node from the remaining part of the WSN. A mobile sink …

In wireless sensor networks (WSNs), the energy-hole or hotspot problem is an important,
challenging issue because it isolates some nodes from the sink. The hotspot problem is …

Abstract Data collection using Mobile Sink (MS) is one of the best approaches to address the
hot spot issue resulting from multihop data collection and extend the lifetime of Wireless …

Energy conservation is one of the main problems in a wireless sensor network (WSN).
Compared with a single cluster head (CH), a dual CH optimization was proposed for less …

Recently, a number of applications in military and environmental monitoring have made
wireless sensor networks (WSNs) a research center. Data collection from mobile sinks is …

Abstract Wireless Sensor Networks (WSNs), as the fundamental infrastructure, are
indispensable for the Industrial Internet of Things (IIoT). In particular, the security and …

This paper deals with the problem of large-scale data collection in wireless sensor networks
equipped with multiple multi-interface mobile sinks. Employing mobile sinks for data …

In the clustering routing protocol, prolonging the lifetime of the sensor network depends to a
large extent on the rationality of the cluster head node selection. The selection of cluster …
