Wireless sensor network (WSN) is a group of small power-constrained nodes that sense
data and communicate it to the base station (BS). These nodes cover a vast region of …

Energy efficiency has been a hot research topic for many years and many routing algorithms
have been proposed to improve energy efficiency and to prolong lifetime for wireless sensor …

In this paper, the blockchain technology is utilized to build the first incentive mechanism of
nodes as per data storage for wireless sensor networks (WSNs). In our system, the nodes …

In wireless sensor network, a large number of sensor nodes are distributed to cover a certain
area. Sensor node is little in size with restricted processing power, memory, and limited …

In wireless sensor networks (WSNs), nodes have limited energy and cannot be recharged.
In order to tackle this problem, clustering methods are employed to optimize energy …

Traditional wireless sensor networks (WSNs) with one static sink node suffer from the well-
known hot spot problem, that of sensor nodes near the static sink bear more traffic load than …

Wireless sensor networks have been employed widely in various fields, including military,
health care, and manufacturing applications. However, the sensor nodes are limited in terms …

This paper proposes a novel energy-aware and layering-based clustering and routing
protocol (EA-CRP) for gathering data in WSNs. The main goal of EA-CRP is to reduce the …

With the development of Internet of Things (IoT), more and more sensors, actuators and
mobile devices have been deployed into our daily lives. The result is that tremendous data …

In wireless sensor networks (WSNs), the sensed data by sensors need to be gathered, so
that one very important application is periodical data collection. There is much effort which …
