Energy efficiency is resent issue in wireless sensor network (WSN). Hierarchical routing or Clustering is best solution for reducing energy consumption in WSN. LEACH (Low energy adaptive clustering hierarchy) is good hierarchical protocol. There are many protocols introduced based on LEACH but still have issue of energy efficiency. Lots of research is going on CH (cluster head) election algorithm,...
In order to solve the problems of LEACH (Low Energy Adaptive Clustering Hierarchy) nodes short life cycle and consumption imbalance, the paper proposes an improved algorithm of LEACH. The main idea of the improved algorithm is to consider the current position and the current energy of the node, which can be more evenly distributed cluster head, in order to prolong the life cycle of the node. A comparison...
In Wireless Sensor Network, the total energy consumption determines the lifetime of the entire network. As a result, a number of recently-designed energy-efficient routing algorithm stated that clustering approach has an important issue for organizing a network into a connected hierarchy and increasing the network lifetime. The clustering hierarchical model consists in two main steps, cluster heads...
Recently, Wireless Sensor Network (WSN) had grown rapidly. But, The WSN operates as a restricted energy in vulnerable environment. LEACH is a hierarchical clustering protocol that provides efficient consumption of energy. Existences of very large and very small clusters affect performance. FZ-LEACH improves performance for Large-scale WSN. In this paper, we find problem of FZ-LEACH and propose a solution...
In this paper, a new heterogeneous wireless sensor networks (HWSNs) model with energy heterogeneity and computational heterogeneity is proposed. Energy dissipation structure and optimal cluster head number function in HWSNs are obtained based on mathematics model, providing the guidance for designing energy efficient clustering routing protocols. Besides, we propose a new energy efficient routing...
Future wireless sensor networks (WSNs) are predicted to use thousands of sensor nodes. Moreover due to the limited resources of sensor nodes a core challenge is how to prolong WSN lifetime. Group-based or cluster-based approaches are well known methods used to enhance the lifetime and performance of such large scale networks. For these approaches each group leader in a group of nodes plays an important...
