Due to the necessity of saving energy cost in low-powered devices, extending the lifetime of a sensor node powered by battery in both homogeneous and heterogeneous wireless sensor networks (WSNs) is area of interest. To save battery power in sensor networks, many research works including low energy adaptive clustering hierarchy (LEACH) and its variants use clustering techniques to reduce energy...

This paper gives a brief description about some routing protocols like EEE LEACH, LEACH and Direct Transmission protocol (DTx) in Wireless Sensor Network (WSN) and a comparison study of these protocols based on some performance matrices. Addition to this an attempt is done to calculate their transmission time and throughput. To calculate these, MATLAB environment is used. Finally, on the basis ...

Security of Wireless sensor network (WSN) turn out to be a very important issue with the rapid development of WSN that is vulnerable to a wide range of attacks due to deployment in the hostile environment and having limited resources. Clustered Networks have been proposed to reduce the power consumption in sensor networks. LEACH is a clustering based protocol that lessens energy dissipation in ...

Clustering protocols effectively utilize network resources for maximizing the lifetime of a mobile wireless sensor network. However, most of these protocols do not address the sensing coverage efficiency. Recently developed protocols, like LEACH-VF and K-LEACH-VF, take advantage of node mobility to combine sensor placement with clustering protocols to achieve the goal of jointly optimizing the ...

In wireless sensor network the bad distribution for cluster head was not taken into account in traditional clustering algorithm such as LEACH algorithm. However the distribution uniformity for the cluster head in wireless sensor networks is very critical, for the better cluster head distribution could effectively save the communication cost and prolong the the lifespan of the network. The math ...

Wireless Sensor Nodes are deployed in the hostile region to help the user by providing data to the user for the review purpose. These nodes are having limited power as they are battery operated. Hence, routing protocol used to deliver data to end users must be energy efficient to provide prolonged network lifetime. In this paper, we have proposed a decentralized clustering scheme based on seque...

One of the most important issues in Wireless Sensor Networks (WSNs) is severe energy restrictions. As the performance of Sensor Networks is strongly dependence to the network lifetime, researchers seek a way to use node energy supply effectively and increasing network lifetime. As a consequence, it is crucial to use routing algorithms result in decrease energy consumption and better bandwidth u...
