One of the fundamental services provided by a wireless sensor network (WSN) is the
monitoring of a specified region of interest (RoI). Considering the fact that emergence of …

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 …

The Internet of Things (IoT) evolving from the conventional wireless sensor networks (WSNs)
with more smart sensors has attracted significant attention. As one of the most crucial metrics …

The deployment of Internet of Things (IoT) temperature sensors in urban areas is essential
for the monitoring and understanding of the thermal environment. However, accurate …

Abstract Wireless Sensor Networks (WSNs) are a special class of wireless networks where
randomly and densely distributed sensor nodes take local measurements of a phenomenon …

Sensor nodes located in the vicinity of a static sink drain rapidly their batteries since they
have to carry more traffic burden. This situation results in network partition, holes as well as …

In the carrier-based coverage repair problem, a single mobile robot replaces damaged
sensors by picking up spare ones in the region of interest or carrying them from a base …

The coverage problem is critical for wireless sensor network. The quality of coverage is the
key factor of service quality. The network holes can decrease the network connectivity and …

Aiming at the deficiencies of the population of the bat algorithm, which is easy to fall into the
local optimum, the bat algorithm with inertia factor and Lévy flight strategy is proposed and …

Node deployment is a basic requirement of active monitoring in hybrid sensor networks,
especially for unmanned monitoring and dangerous scenes. This paper proposes an …
