In Wireless Sensor Networks (WSNs), sensor nodes play the most important role. These
sensor nodes are mainly un-chargeable, so it an issue regarding lifetime of the network. The …

Wireless sensor networks have many sensor nodes with a limited energy in a limited area.
One of key issues in wireless sensor networks is to prolong the network lifetime. In this …

In recent years, there has been increasing research interest in Wireless Sensor Networks
(WSNs). WSN consist of small nodes with sensing, processing and wireless communications …

In the past few years, the use of wireless sensor networks (WSNs) potentially increased in
applications such as intrusion detection, forest fire detection, disaster management and …

One of the important problems for wireless sensor networks is increasing the network
lifetime. Clustering is an efficient technique for prolonging the lifetime of wireless sensor …

The energy of a node in Wireless Sensor Networks (WSNs) is limited, so WSNs need energy
saving algorithms. We propose an unequal clustering algorithm based on spacing and RE …

One of the main challenges of wireless sensor network is how to improve its life time. The
limited energy of nodes is the main obstacle. We may overcome this problem by optimizing …
