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...

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...

Low-Energy Adaptive Clustering Hierarchy (LEACH) is one of the most popular distributed cluster-based routing protocols in wireless sensor networks. Clustering algorithm of the LEACH is simple but offers no guarantee about even distribution of cluster heads over the network. And it assumes that each cluster head transmits data to sink over a single hop. In this paper, we propose a new method fo...

Increased use of Wireless sensor Networks (WSNs) in variety of applications has enabled the designers to create autonomous sensors, which can be deployed randomly, without human supervision, for the purpose of sensing and communicating valuable data. Many energy-efficient routing protocols are designed for WSNs based on clustering structure. In this paper, we have proposed iMODLEACH protocol wh...

Since all sensor nodes in wireless sensor networks work by their own embedded batteries, if a node runs out of its battery, the sensor network cannot operate normally. In this situation we should employ the routing protocols which can consume the energy of nodes efficiently. Many protocols for energy efficient routing in sensor networks have been suggested but LEACH and PEGASIS are most well kn...

Wireless Sensor Network (WSN) has been considered as a promising method for reliably monitoring civil and military environment in hazardous or dangerous conditions. Usually, sensor webs consisting of nodes with limited power and limited wireless communications are deployed to collect useful information from the field. Due to these reasons, how to improve energy efficiency is a critical issue fo...
