International Journal of Computer Applications, 2015
Wireless Sensor Networks are made up of restricted energy driven resources. When the installation setup of sensor nodes are over usually they are inaccessible to the user. Hence the replacement of battery source is not feasible. In order to boost the life span of the network, the key design issue is to be enhanced which is energy efficiency. With the restricted energy supply, a number of network layer protocol have been anticipated to increase the operative life span of the network. LEACH(Low Energy Adaptive Clustering Hierarchy) is a Hierarchical Clustering Protocol provides solution for such issues. EEACRA(Energy Efficient Adaptive Cluster Routing Algorithm) a variant of LEACH have been proposed to improve the deficiency of LEACH which is based on the energy decision condition.The proposed EECRL(Energy Efficient Clustering Routing for LEACH)shows several improvement for whole network energy consumption and effectively prolong the network life cycle.

As these networks are energy constrained, energy efficiency in routing is crucial research issue nowadays. Many flat and hierarchical protocols have been proposed to improve the network lifetime. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is a well known energy efficient hierarchical routing protocol in WSN. In LEACH, nodes are divided into clusters and cluster heads for clusters are selected. Nodes send their data to respective cluster head and the cluster head is responsible to send the collected and aggregated data directly to the sink. This paper evaluates the performance of the LEACH protocol and gives an improvement to it for energy efficiency. The proposed protocol considers many parameters like residual energy and distance from base station etc. for cluster head selection and energy efficient routing.
Wireless Sensor Network (WSN) is an emerging technology that shows great promise for various futuristic applications both for mass public and military. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. They are very useful for military, environmental, and scientific applications to name a few. Routing is a very important phase in any type of communication. Moreover, Routing procedure consumes more power than any other phase. Therefore, if some changes are made in this phase, then drastic changes in energy consumption may be observed. LEACH (Low Energy Adaptive Clustering Hierarchy) is designed in such a way that it consumes less energy comparatively. If still, changes are done then it can be improved. In this paper, LEACH protocol functioning is explained. In addition to this, variants of LEACH are discussed in brief.
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.
Ee-Leach(Low Energy Adaptive Clustering Hierarchy) Modified Protocol
A wireless sensor network is made by many homogeneous and/or nodes which can sense data and communicate to each other. As energy is a scarce resource in WSN, the main issue is energy efficient routing. Many flat and hierarchical protocols have been projected to enhance the network lifetime. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is a basic energy efficient hierarchical routing protocol in WSN. In LEACH, cluster heads are selected and cluster is formed by joining non cluster head nodes. Member nodes transmit the data to respective cluster head and the cluster head is conscientious to transmit the gathered and aggregated data directly to the base station. This paper examines the performance of the conventional LEACH protocol and gives an enhancement to it for energy efficiency. The proposed protocol considers many parameters like residual energy and distance from base station etc. for cluster head selection and energy efficient routing.
ENERGY AWARE DYNAMIC CLUSTERING AND HIERARCHICAL ROUTING BASED ON LEACH FOR WSN
TJPRC, 2013
Optimization of resource utilization especially energy with higher Quality of Service (QoS) parameter such as packet delivery ratio etc, is an open and active research issue in wireless sensor networks (WSN). Existing methods such as direct transmission, multi-hop routing, minimum transmission energy and static clustering methods were not optimal for certain applications. LEACH protocol is built on the assumption of direct communication between cluster head and Sink nodes. Where as in many real time applications cluster head to cluster head communication is required. The Proposed work in this paper is an improvement in LEACH protocol by means of dynamic cluster head selection and routing from Cluster head to sink node through other cluster heads and their by increases the network life time. The proposed work gives better performance of network life time, low energy consumption compared to LEACH.
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.

Due to the wide range of applications the use of wireless sensor networks (WSNs) in past few years have increased a lot and it has become a hot research area now a days. One of the important issues in wireless sensor network is the inherent limited battery power in network sensor nodes. Since most of the energy is consumed by the radio transmission and reception, energy efficient routing protocol is required to enhance the lifetime of WSN.
