Wireless Sensor Networks (WSNs) are considered to be among the most important scientific
domains. Yet, the exploitation of WSNs suffers from the severe energy restrictions of their …

In the past two decades, network clustering has been proven as efficient approach for data
collection and routing in wireless sensor networks (WSNs). It provides several advantages …

Battery-powered sensor nodes encounter substantial energy constraints, especially in linear
wireless sensor network (LWSN) applications like border surveillance and road, bridge …

Abstract Wireless Sensor Networks (WSNs) frequently have distinguished amount of data
loss, causing data integrity issues. Sensor nodes are inherently a cheap piece of hardware …

In recent times, there has been a surge in the popularity of nature-inspired algorithms (NIAs)

Abstract We consider the Backup Placement problem in networks in the CONGEST
distributed setting. Given a network graph G=(V, E), the goal of each vertex v∈ V is selecting …

Energy efficiency is the major issue that arises in Wireless Sensor Networks (WSNs).
Batteries that are typically the main power source of a WSN have a restricted lifetime. Hence …

A novel technique is proposed to optimize energy efficiency for wireless networks based on
hierarchical mobile clustering. The new bi-level clustering technique minimizes mutual …

Clustering is one of the essential techniques in wireless sensor network (WSN). Clustering is
done to achieve the energy efficiency, improve network lifetime and the scalability of the …
