Research On Energy Efficient Routing Protocol LEACH For Wireless Sensor Networks
In recent era of Wireless Technology, energy efficient design and latest wireless technologies have enabled new exciting applications for wireless devices. These types of applications covers a wide range including real time and streaming video and audio delivery, transfer of large amount of data from one device to another. These applications require high performance on the network, they usually suffering from resource constraints. Wireless devices are often having limited energy resource because nodes are battery operated. This makes application with limited bandwidth & making the transfer error prone. A wireless sensor network which consists of a group of sensor nodes enables the monitoring of a variety of environments for applications. In WSNs, it is very critical to operate sensor network for a long time. In this case, data fusion is helpful to reduce the amount of data transmitted between sensor nodes and base station. The LEACH (Low Energy Adaptive Clustering Hierarchy) protocol is an elegant solution to this problem. In this paper, LEACH protocol is discussed.

A Survey on LEACH-Based Energy Aware Protocols for Wireless Sensor Networks
2013
Due to the advances in wireless communications and electronics technology, Wireless Sensor Networks (WSNs) are used in many applications such as civil and military application. A WSN is composed on many nodes each of which is basically equipped with a sensing device to collect data from the environment, a processing unit to do some operations on data, a transceiver to send and receive collected, and an energy source to provide the required energy to operate (usually a battery). In most applications sensor nodes are randomly deployed in the field. Therefore, battery replacement or charging is considered not practical. As a result, routing protocols must be energy-efficient to prolong the network lifetime. Researchers have been working to develop routing techniques that enhances the WSN lifetime among which is the hierarchical routing. In this paper, we present a recent survey of hierarchical routing protocols which are based on LEACH protocol. Specifically, we will show the network life time and energy consumption for each protocol. Furthermore, a comparison of these protocols in terms of advantages (improvements over LEACH), disadvantages, assumptions, and the Cluster Head selection criteria are provided. 1
This paper propose a new low power consumption routing protocol for wireless sensor networks based on clustering approach. The suggest protocol is to use energy more evenly selected node cluster-heads, and save the energy dissipated when routing captured data to the base station. Simulation results have shown that suggest protocol allows a reduction in energy dissipation and a life of greater network. Various hierarchical routing solutions practice clustering techniques, to reduce energy consumption and enable scaling; The KOCA (K-hop Overlapping Clustering Algorithm) forms overlapped K-Clusters (cluster with K-hop) to enable inter-cluster multi-hop routing; and the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol, whichever arrange the sensors nodes as a layered clustering construction to decrease data delivery time. In order to illustrate the substantial assets of KOCA, the simulations show the impact of mobility on the performance of sensors LEACH and M-LEACH (Multi-hop Low Energy Adaptive Clustering Hierarchy) in WSNs (Wireless sensor networks) environments. Therefore, the results obtained have shown that the mobility has a significant impact on the performance of these two protocols in terms of lifetime of the network and the number of data sent to the base station packets. The KOCA provided better performance than these two protocols. The simulations applying the NS2 simulator present the protocol perform good presentation in both delivering data and energy conservation. It create a small number of clusters, and distributes energy consumption equally on the network.
Wireless sensor network is an emerging technology which has an immense scope of research and development. It has the potential of quick capturing, processing and transferring data with high resolution to the base station. WSN consists of multiple sensor nodes, these nodes have low storage capability and limited battery life which dies due to the computation and transmission of data. It is not feasible to replace these batteries due to their placement in isolated areas. In this paper we will emphasize on maximizing energy efficiency and improvement of life span of network. Clustering is the technique which balances the load on sensor network and reduces energy dissipation. LEACH is one of the selforganized clustering routing protocols which will be explored and modified. Further we will compare various LEACH protocols on the basis of their features and we will throw some light on future possibilities and outdo
Energy Efficient LEACH protocol for Wireless Sensor Network (I-LEACH)
IJSRD, 2013
In the wireless sensor networks (WSNs), the sensor nodes (called motes) are usually scattered in a sensor field an area in which the sensor nodes are deployed. These motes are small in size and have limited processing power, memory and battery life. In WSNs, conservation of energy, which is directly related to network life time, is considered relatively more important souse of energy efficient routing algorithms is one of the ways to reduce the energy conservation. In general, routing algorithms in WSNs can be divided into flat, hierarchical and location based routing. There are two reasons behind the hierarchical routing Low Energy Adaptive Clustering Hierarchy (LEACH) protocol be in explored. One, the sensor networks are dense and a lot of redundancy is involved in communication. Second, in order to increase the scalability of the sensor network keeping in mind the security aspects of communication. Cluster based routing holds great promise for many to one and one to many communication paradigms that are pre valentines or networks.
A Novel Improvement in LEACH Protocol for Decreasing Energy Loss in Wireless Sensor Networks
Port-Said Engineering Research Journal, 2021
One of the most important Internet of Things technologies is the Wireless Sensor Network (WSN), and it has recently gained a lot of interest because of its applications in monitoring, army, health, automation, agricultural, environment, and underwater. Two of the most important requirements for observing and detecting wireless topics within WSN are clarity of information disseminated and energy efficient. As a result, several forms of study are carried out. Many routing protocols that are based on topology with a hierarchical and clustering structure have been created to give a better result for deducing the network's energy exhaustion in WSN. However, these protocols do not consider all the necessary and important parameters for extending network life. In this suggested paper, we introduce two new methods to boost the WSN which raises energy-efficient and network lifetime. The simulated results of the proposed approaches are then compared to the prime LEACH Protocol with fixing...
An energy efficient routing protocol is the major attentiveness for researcher in field of Wireless Sensor Networks (WSNs). In this paper, we present some energy efficient hierarchal routing protocols, prosper from conventional Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol. Fundamental objective of our consideration is to analyze, how these ex-tended routing protocols work in order to optimize lifetime of network nodes and how quality of routing protocols is improved for WSNs. Furthermore, this paper also emphasizes on some issues experienced by LEACH and also explains how these issues are tackled by other enhanced routing protocols from classi-cal LEACH. We analytically compare the features and performance issues of each hierarchal routing protocol. We also simulate selected clustering routing protocols for our study in order to elaborate the enhancement achieved by ameliorate routing protocols.
ENERGY-BALANCED IMPROVED LEACH ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORKS
A proper sensor node clustering is an effective topology control that can balance energy consumption among sensor nodes and increase network scalability and life time. As the use of wireless sensor networks (WSNs) has grown enormously, the need for energy-efficient routing and data aggregation has also risen. LEACH （Low Energy Adaptive Cluster Hierarchy） is a hierarchical clustering protocol that provides an elegant solution for such protocols. Random clustering is the main deficiency of LEACH. In this paper an energy balanced clustering approach is proposed, in which the K-mean clustering algorithm is applied. It is centralized clustering algorithm that based on minimum energy clustering to form optimal clusters. For the candidate nodes, the location and the residual energy are used as key parameters to select the cluster head (CH). The method shows that the proposed approach outperforms LEACH in terms of energy conservation and network life time prolonging.
