Thus energy efficiency is one of the most important issues and designing energy efficient protocols is critical for prolonging the lifetime. This paper introduces a two routing protocols namely, LEACH and EAMMH in Homogenous & Heterogeneous system supported by simulation scripts, and analysis of the results against known metrics with energy and network lifetime being major among them. Simulation results using MATLAB shows that the proposed EAMMH in Homogenous & Heterogeneous system significantly reduces energy consumption and increases the total lifetime of the wireless sensor network.
An enhanced energy-efficient routing protocol for wireless sensor network
International Journal of Electrical and Computer Engineering (IJECE), 2020
Recent few years, Wireless Sensor Network (WSN) has been an increasingly important technology that has been applied in almost all domains, even in complex environments where human activity is impossible. In WSN, various factors are impacted energy consumption, such as communication protocols, packet data transmission, and limited battery. So, the lifespan of the WSNs is limited. In this context, energy efficiency is the factor most attracted by many researchers. In this paper, we proposed a new improved LEACH routing protocol. This proposed protocol based on the current energy to select cluster-heads, and it uses a root cluster-head with more current energy and low distance to the sink to gather all data, then sends it to the sink. The simulation results in MATLAB confirmed that the proposed algorithm performed better than the conventional LEACH protocol, and increased the network lifetime in WSN.

As the use of wireless sensor networks is increasing day by day at the same time they are facing the problem of energy constraint in terms of limited battery life time. Network lifetime of system is directly related to energy dissipation in sensor nodes. Hence more energy dissipation results in decreasing network lifetime of sensor network. This paper concerns with investigation of energy efficiency and network lifetime of three routing protocols: LEACH, PEGASIS and Multi-chain PEGASIS; in wireless sensor network. This paper also concentrates on finding the most energy efficient protocol so that energy efficient protocol that have high network lifetime can be utilized in wireless sensor network.
A multi-hop routing protocol for an energy-efficient in wireless sensor network
International Journal of Electrical and Computer Engineering (IJECE), 2023
The low-energy adaptive clustering hierarchy (LEACH) protocol has been developed to be implemented in wireless sensor networks (WSNs) systems such as healthcare and military systems. LEACH protocol depends on clustering the employed sensors and electing one cluster head (CH) for each cluster. The CH nodes are changed periodically to evenly distribute the energy load among sensors. Updating the CH node requires electing different CH and re-clustering sensors. This process consumes sensors' energy due to sending and receiving many broadcast and unicast messages thus reduces the network lifetime, which is regarded as a significant issue in LEACH. This research develops a new approach based on modifying the LEACH protocol to minimize the need of updating the cluster head. The proposal aims to extend the WSN's lifetime by maintaining the sensor nodes' energy. The suggested approach has been evaluated and shown remarkable efficiency in comparison with basic LEACH protocol and not-clustered protocol in terms of extending network lifetime and reducing the required sent messages in the network reflected by 15%, and, in addition, reducing the need to reformatting the clusters frequently and saving network resources.
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
Enhanced LEACH Protocol based Energy Efficient Routing in Wireless Sensor Network
The nodes of the Wireless Sensor Network (WSN) have a limited battery power and unchangeable because it is normally deployed in geographical areas where the human interventions are limited. The applications of WSN requires a continuous connection between the nodes and BS should be maintain to transmit the data even when there is no data to transmitted. Therefore, the energy efficient protocols are the primary need of WSN. Many algorithms were developed and this paper presents a novel protocol " Enhanced LEACH " to improve energy efficiency, lifetime and scalability of the network. This proposed scheme introduces some parameters in CH election like distance between nodes, residual energy of nodes and so on. The parameters are combined with LEACH threshold probability function to elect the best CH. The elected CH follows a data transmission power levels in order to extend the lifetime of the network. Enhanced LEACH is compared with LEACH using the metrics such as throughput, lifetime, low amount of energy as well. The simulation results show the proposed scheme consumes less energy, low cost, less collision, less transmission time and increase network lifetime when compared to LEACH.
