Energy problem is a key issue for Wireless Sensor Network. It's a good idea to select a head
node for data aggregation to reduce the energy of data transmission. However, many …

ABSTRACT A wireless sensor network is a resource constraint network, in which all sensor
nodes have limited resources. In order to save resources and energy, data must be …

Clustering provides an effective way to prolong the lifetime of wireless sensor networks.
However, the head node may die much faster than other nodes due to its overburden. In this …

In recent years, wireless sensor networks have been used for various applications such as
environmental monitoring, military and medical applications. A wireless sensor network uses …

Abstract In Wireless Sensor Networks (WSN), one of the major issues is to maximize the
network lifetime. Since all sensor nodes directly send the data to the Base station, the …
