Energy Efficient Cluster Based Routing Protocol for Wireless Sensor Networks
Wireless sensor network are sophisticated systems that are used to collect data from an inaccessible environment. They consist of base station and hundred to thousand of tiny nodes called sensor nodes. Nodes in the sensor network are constrained by energy. The sensor networks where base station is very distant from the sensor field, the energy efficiency in the working of sensor networks plays an important role in the lifetime of the sensor networks. To prolong the life of the sensor network energy efficient techniques for routing is an important issue. In this paper we proposed a new algorithm for cluster head selection in each cluster for each round of communication. The clusters are fixed through out the network life time. Our proposed work is based on LEACH and LEACH-C. The protocol works efficiently to increase the overall network lifetime and outperforms LEACH in terms of minimizing the overall energy consumption.
Wireless sensor network are emerging in various fields like environmental monitoring, mining, surveillance system, medical monitoring. LEACH protocol is one of the predominantly used clustering routing protocols in wireless sensor networks. In Leach each node has equal chance to become a cluster head which make the energy dissipated of each node be moderately balanced. We have pioneered an improved algorithm named as Novel Leach based on Leach protocol. The proposed algorithm shows the significant improvement in network lifetime .Comparison of proposed algorithm is done with basic leach in terms of network life time, cluster head selection, energy consumption, and data transmission to base station. The simulation results shows that proposed algorithm can reduce network energy consumption and prolong network life commendably. Simulation of our protocol is done with Matlab.
Cluster Head Selection for in Wireless Sensor Networks
Wireless sensor network consists of several distributed sensor nodes. It is used for several environmental applications, military applications and health related applications. To prolong the lifetime of the sensor nodes, designing efficient routing protocols is critical. Most of the research in energy efficient data gathering in data centric applications of wireless sensor networks is motivated by LEACH (Low Energy Adaptive Clustering Hierarchy) scheme. It allows the rotation of cluster head role among the sensor nodes and tries to distribute the energy consumption over the network. Selection of sensor node for such role rotations greatly affects the energy efficiency of the network. Some of the routing protocol has a drawback that the cluster is not evenly distributed due to its randomized rotation of local cluster head. We have surveyed several existing methods for selecting energy efficient cluster head in wireless sensor networks. We have proposed an energy efficient cluster head selection method in which the cluster head selection and replacement cost is reduced and ultimately the network lifetime is increased. Using our proposed method, network life time is increased compared to existing methods. Keywords: WSN, CH, BS, LEACH, LEACH-B, LEACH-F
A new energy aware cluster head selection for LEACH in wireless sensor networks
IET Wireless Sensor Systems, 2021
Internet of Things (IoTs) as a new network pattern for the intelligent world usually uses wireless sensor networks (WSNs) as a perception layer which consisted of numerous number of sensor nodes scattered in the environment to gather intended information. The selected information then is sent to a base station (BS) to be sent to cloud server for further processing. Since the energy of sensor nodes is limited, the most significant challenge in these networks is reducing the energy consumption of the network. It is proved that dividing the network to clusters can significantly reduce the energy consumption. One of the most popular clustering protocols in WSNs is the Low-Energy Adaptive Clustering Hierarchy (LEACH). In this protocol, cluster heads (CHs) are selected randomly which results in poor performance in real scenarios. In this article, a new energy aware CH selection algorithm is proposed which selects CHs based on the residual energy, the position and centrality of nodes. It uses a variable range upon which the centrality and the number of neighbours of each node are calculated. Simulation results show that the proposed algorithm outperforms LEACH, Multi-hope Routing with LEACH (MR-LEACH) and Enhanced Multi-hop LEACH (EM-LEACH) in terms of reducing energy consumption, increasing network lifetime and improving network reliability.

A new energy aware routing protocol to optimize energy consumption and prolong network lifetime for Wireless Sensor Networks (WSNs) had been proposed in this paper. Cluster based routing techniques like the conventional Low Energy Adaptive Clustering Hierarchy (LEACH) are used to achieve scalable solutions and extend the network lifetime until the last node dies. Improved Energy Efficient LEACH (IMP-EEL) has been proposed in this work and compared with the other existing algorithms like LEACH, Residual Energy LEACH (RES-EL) and Distributed Residual Energy LEACH (DIS-RES-EL). The proposed algorithm (IMP-RES-EL) outperformed all the other algorithms in extending network lifetime, network stability, sending aggregated packets to Cluster heads (CHs) and to Base station(BS) and CH formation during their entire lifetime considered. With optimum routing established within the network as per the newly proposed clustering threshold, IMP-EEL has significantly reduced energy consumption and maintained 72% more energy efficiency than the LEACH homogeneous system.
Energy Efficient Cluster Based Routing Mechanism for Wireless Sensor Networks
Journal of emerging technologies and innovative research, 2018
The Wireless sensor networks is one of the premier research are from past few decades, so the need to maintain energy efficient routing between from the nodes to base station, proper data aggregation and scalability is the important concern. In hierarchical routing LEACH is one of the energy efficient clustering protocol, but only the problem is size of the clusters are not same either they may be small or large, which causes to reduce the network lifetime. The other protocol FZ-LEACH addresses the LEACH problem by selecting some random cluster heads, but not energy efficient. In this paper, we propose a new protocol enhanced far-zone cluster-based routing protocol with optimized algorithm (FZ-CRP), form's cluster heads and zone heads based on the intra communication cost and energy. If the node's energy is the less than or equal to average minimum reach ability power then that node is said to be in far zone, far zone node transmits the data to base station via far zone, cluster heads. The performance of the proposed is better when we compare with existed scenarios.

An Efficient Energy Utilization based Cluster Head Selection for Mobile Sensor Network
International Journal of Computer Applications
The sensor nodes in WSN (Wireless Sensor Network) are energy dependent and each and every functioning is only possible to exhaust some amount of power or energy. The WSN is decentralized network and nodes are free to move in limited radio range for communication. The routing protocol is performing important role for communication and better routing strategy is reduces the energy consumption and enhances the utilization of energy. LEACH is the energy efficient protocol and this protocol is only designed for energy based routing. In this paper we proposed a new multipath routing strategy with higher energy node selection scheme for selection of Cluster Head (CH) and route establishment. The performance of proposed LEACH protocol is compare with normal LEACH protocol in WSN. The energy utilization of nodes is improves if the possibility of link breakage is reduced and the proposed energy approach is established strong link in dynamic network. The proposed scheme ignores the shortest path routing procedure but established the reliable path in between source to destination. The packet retransmission is consumes the lot of extra energy for sending or forwarding the same data and also not sure, in next time data is successful deliver to destination. The multipath routing is improves the reliability of link in terms of mobility. If the node/s is the part of link and goes to out of range then instantly the alternative route is present for data delivery in dynamic network. The network performance is measure through performance metrics like throughput, routing overhead and number of survive nodes in dynamic network.
New Approach for Selecting Cluster Head based on LEACH Protocol for Wireless Sensor Networks
Proceedings of the 12th International Conference on Evaluation of Novel Approaches to Software Engineering, 2017
From hierarchical routing protocols, Low-Energy Adaptive Clustering Hierarchy (LEACH) has been considered as one of the effective algorithms that optimize energy and prolong the lifetime of network. In this paper, we propose a new approach of electing Cluster Head (CH) based on LEACH protocol. The selection of Cluster Head (CH) in LEACH is carried out randomly. In our proposed approach, we consider three fundamental criteria: the remaining energy, the number of neighbours within cluster range and the distance between node and CH. In fact, in our algorithm, we include these factors in calculation of threshold. Simulation results shows that our proposed approach beats LEACH protocol in regards of prolonging the lifetime of network and saving residual energy.
A Centralized Energy Efficient Distance Based Routing Protocol for Wireless Sensor Networks
Journal of Sensors, 2016
Wireless sensor network (WSN) typically consists of a large number of low cost wireless sensor nodes which collect and send various messages to a base station (BS). WSN nodes are small battery powered devices having limited energy resources. Replacement of such energy resources is not easy for thousands of nodes as they are inaccessible to users after their deployment. This generates a requirement of energy efficient routing protocol for increasing network lifetime while minimizing energy consumption. Low Energy Adaptive Clustering Hierarchy (LEACH) is a widely used classic clustering algorithm in WSNs. In this paper, we propose a Centralized Energy Efficient Distance (CEED) based routing protocol to evenly distribute energy dissipation among all sensor nodes. We calculate optimum number of cluster heads based on LEACH’s energy dissipation model. We propose a distributed cluster head selection algorithm based on dissipated energy of a node and its distance to BS. Moreover, we extend...
