This paper proposed a EELP (Energy Efficient LEACH Protocol) routing protocol based on LEACH. LEACH (Low Energy Adaptive Clustering Hierarchy) is seminal work in the area of clustering-based protocol, proposed by W.B. Heinzelman. In EELP, all nodes are organized sequentially in the rooms of the apartments of a multi-story building. In this protocol, cluster head (CH) selection is determined as the...
Wireless sensor networks have serious energy constrain, since external power sources are typically unavailable. Typical wireless sensor nodes use batteries or fuel cells as the power source. The primary design goal of routing protocols is to efficiently use the energy of sensor nodes and prolong the survival time of the network. This paper analyzes the classical clustering routing protocol LEACH and...
Energy efficiency and data reliability have always been the key problem in WSN. In this paper, firstly, a selection of cluster head algorithm is designed which is able to detect the energy change of nodes, rapidly ascertain new cluster head, and avoid excessive energy consumption between cluster head and cluster nodes. Secondly, differentiated service is introduced in our algorithm which makes achieve...
Design an energy efficient routing protocol for wireless sensor network is a very important issue because of the constrained energy of sensor nodes. In this paper, an energy efficient routing protocol (VBT-EBHRP) is proposed. In this protocol, a virtual backbone tree is constructed and based on the virtual backbone tree, a routing tree is constructed. The residual energies of the virtual backbone...
Wireless sensor networks are composed of cheap sensor nodes with limited energy resources. These networks require robust wireless communication protocols that are energy efficient in order to prolong the lifetime of the entire network. This paper studies the routing protocols and analyzes the performance of LEACH (low-energy adaptive clustering hierarchy) in-depth. It is found that the cluster heads...
In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy-efficient routing protocol. LEACH is very effective in enhancing nodes' lifetime from routing's aspect.This paper proposes an improved LEACH protocol for data gathering and aggregation in wireless sensor networks. Conventional LEACH includes distributed...
In this paper, the authors exposes the problems in LEACH when the network is in a large scope, a new routing protocol named LEACH-L is designed. The results of experiments show that LEACH-L can balance the energy dispatch of the sensors in different areas and make a longer lifetime of WSNs when the scope of WSNs goes into larger.
