Over the last several years, various clustering algorithms for wireless sensor networks have
been proposed to prolong network lifetime. Most clustering algorithms provide an equal …

Because a sensor node in wireless sensor networks is battery operated and energy
constrained, reducing energy consumption of each node is one of important issues. The …

Radio transmission and reception consumes a lot of energy in a wireless sensor network
(WSN), which are made of low-cost, low-power, small in size, and multifunctional sensor …

In this paper, a Single-Hop Unequal Clustering (SHUC) algorithm is proposed for wireless
sensor networks. The SHUC algorithm consists of three different parts. Firstly, an average …

Sensor nodes in sensor networks often gather data and deliver them to the sink. However,
the energy and radio range constraints force them to cooperate in transmitting the data to the …

The necessity of wireless sensor networks is increasing in the recent years. So many
researches are studied in wireless sensor networks. The clustering algorithm provides an …

A new unequal clustering protocol with local re-clustering mechanism is proposed to
mitigate the'hot spot'problem and thereby prolong the network lifetime of a wireless sensor …

In order to prolong the lifetime of sensor nodes, wireless sensor networks are partitioned into
clusters. The most of the proposed Equal Clustering algorithms do not consider location of …
