As a classic clustering algorithm, LEACH is widely used in wireless sensor networks. Due to the random cluster head selection process, LEACH does not guarantee optimization for the number and position of cluster heads. In order to further optimize LEACH, an optimal energyefficient cluster-heads selection algorithm LEACH-G for LEACH protocol is presented. We calculate the optimal number of clust...

Clustering is an effective technique that can greatly contribute to overall system scalability, lifetime, and energy efficiency in wireless sensor networks (WSNs). In this paper, we propose an energy efficient clustering algorithm for WSNs based on the LEACH algorithm. LEACH (Low Energy Adaptive Clustering Hierarchy) is one of the most well known energy efficient clustering algorithms for WSNs....

Routing is an important challenge in WSN due to the presence of hundreds or thousands of sensor nodes. Low Energy Adaptive Clustering Hierarchy (LEACH) is a hierarchical routing and data dissemination protocol. LEACH divides a network domain into several sub-domains that are called clusters. Non-uniformity of cluster distribution and CHs selection without considering the positions of other sens...

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

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...

This paper summarizes the work used to improve low energy adaptive cluster hierarchy (LEACH) algorithm and proposes a new protocol “Seeded LEACH-KED” in order to increase the network lifetime and then compare its result with the LEACH , LEACH-C and LEACH-KED. Prolonging network lifetime is the way to provide energy efficient WSNs. This research is inspired by the fact that LEACH occupies a very...

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...

Due to the importance and need of wireless sensor networks in several applications, lots research has been carried out. The utmost challenging issue is regarding energy depletion network such that reducing consumed leads extending lifetime. most popular routing algorithm for purpose LEACH. Regrettably, it some limitations, this work produces Sectored-LEACH, which proposes solutions these limita...

There is tremendous increase in popularity of WSNs as the sensor network connects the virtual world and physical world together. Sensors nodes can be deployed in hostile environment where there is no access of human beings. Sensor nodes rely on battery power where it becomes a difficult task to replace the battery. So to improve the networks energy is very important task. To overcome this probl...
