Wireless sensor networks (WSNs) have attracted much attention in recent years. In the many-
to-one WSNs, the nodes located around the sink relay the data from other sensor nodes …

Data aggregation is one of the essential and fundamental processes in Wireless Sensor
Networks (WSNs). When and how to gather data from the sensors to the sink has a direct …

Energy is one of the scarcest resources in wireless sensor network (WSN). One fundamental
way of conserving energy is judicious deployment of sensor nodes within the network area …

Wireless sensor networks (WSNs) have grown excessively due to their various applications
and low installation cost. One of the design challenges of the WSNs is to balance the energy …

Wireless sensor networks (WSNs) have increased in popularity since they play a relevant
role in many applications, such as environmental monitoring, fire detection, and health care …

In wireless sensor networks (WSNs), sensor nodes close to the sink consume more energy
than others because they are burdened with heavier relay traffic destined for the sink and …

In the last years, due to the limited resources of consumer products, energy-saving is known
as one of the design challenges of Wireless Sensor Networks (WSNs). Clustering is a …

Clustering wireless sensor network is an efficient way to reduce the energy consumption of
individual nodes in a cluster. In clustering, multihop routing techniques increase the load of …
