The most important factor within the wireless sensor network is to have effective network usage and increasing the lifetime of the individual nodes in order to operate the wireless network more efficiently. Many routing protocols have been developed for this purpose. One of these is the LEACH protocol presented by Wendi Heinzelman, which is especially well known as a simple and efficient cluste...

Wireless Sensor Network (WSN) comprises of sensor nodes, which form a network by building connections wirelessly, to send detected information from source to destination. Routing Protocols are utilized to shape honest to goodness and littlest routes between a starting node (source) and ending node (destination). Numerous WSN applications use various hierarchical routing protocols. Low Energy Ad...

In wireless sensor networks, sensor node always have a limited power resource. The energy consumed by sensor nodes to transfer the data to its destination becomes critical issue in designing WSN routing protocols. In this paper we propose a cluster routing protocol named I-LEACH to enhance the routing protocol LEACH. In the I-LEACH algorithm, selection of cluster heads is modified by using powe...

Water-environment monitoring network (WMN) is a wireless sensor network based real-time system, which collects, transmits, analyzes and processes water-environment parameters in large area. Both cluster selection mechanisms and energy saving strategies play an important role on designing network routing protocols for the WMN. Since those existing routing algorithms can not be used directly in t...

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 ...

This paper discusses advantages of LEACH Algorithm and the existing improved model which takes the famous hierarchy clustering routing protocol LEACH Algorithm as researching object. Then the paper indicates the problem that in the algorithm capacity factor of cluster head node is not taken into account leading the structure of clusters to be not so reasonable. This research discusses an energy...
