In clustering-based approaches, cluster heads closer to the sink are usually burdened with
much more relay traffic and thus, tend to die early. To address this problem, distance-aware …

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 …

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 …

Hot spots in a wireless sensor network emerge as locations under heavy traffic load. Nodes
in such areas quickly deplete energy resources, leading to disruption in network services …

Recent experimental studies have revealed that a large percentage of wireless links are
lossy and unreliable for data delivery in wireless sensor networks (WSNs). Such findings …

In clustering algorithms for wireless sensor networks, cluster heads close to the sink node
usually encounter much more relay traffic and therefore lose energy rapidly. To address this …

Clustering is a useful technique for reducing energy consumption in wireless sensor
networks (WSN). To achieve a better network lifetime performance, different clustering …

In the paper, we consider a network of energy constrained sensors deployed over a region.
Each sensor node in such a network is systematically gathering and transmitting sensed …

Cluster architectures are an effective approach for organizing sensor networks to balance
the load and prolong network life. To cluster wireless sensor networks, this paper proposes …

We propose a novel scheme that aims to determine the optimal number of clusters based on
the field conditions and the positions of mobile sink nodes. In addition, we merge algorithms …
