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...

Wireless sensor network consists of large number of tiny sensor nodes which are usually deployed in a harsh environment. Self configuration and infrastructure less are the two fundamental properties of sensor networks. Sensor nodes are highly energy constrained devices because they are battery operated devices and due to harsh environment deployment it is impossible to change or recharge their ...

Wireless sensor network is defined as wireless network of sensor nodes in which Routing technique is one of the most challenging issues. One of the major issues in WSNs is the limited battery power of the network sensor nodes. The battery power plays an important role in increasing the lifetime of the nodes. In WSN, routing among various routing technique, energy consumption is one of the most ...

This paper presents a uniform clustering approach which aims to cover entire field with identical clusters scattered over the field. The Cluster head is elected using the LEACH protocol for every cluster locally. Both LEACH and I-LEACH (Identical clustering LEACH) were compared through extensive simulations using NS2 simulator which shows that I-LEACH performs better than LEACH protocol. I-LEAC...

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....

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...

The most important routing protocol LEACH of wireless sensor networks (WSNs) has been incorporated by W. Heinzelman.
