In wireless sensor networks (WSNs), reducing sensor node energy consumption and increasing network lifetime are becoming more and more challenging due to large scale. Hierarchical protocols, especially Low Energy Adaptive Clustering Hierarchy (LEACH), are considered as the best energy-efficient for WSNs. However, LEACH need to be enhanced to support scalability in large WSNs. In this paper, we propose...
An energy efficient routing protocol is the major concern in Wireless Sensor Networks (WSNs). In this paper, we describe LEACH routing protocol and some of its new versions. After that we propose an energy efficient hierarchical routing protocol, developed from LEACH. The basic concept involved in increasing energy efficiency and hence lifetime is to keep radio communication distance as minimum as...
In the field of wireless sensor network, it is one of the hottest issues of current research that how to maintain the quality of network coverage and balance nodes' energy consumption to optimize the network lifetime. This paper analyzed LEACH (low energy adaptive clustering hierarchy) and proposed an energy-efficient distributed clustering algorithm on coverage (ECAC). In the algorithm, the redundancy...
Wireless sensor network consists of hundreds or thousands of tiny sensor nodes, which can monitor remote environment and it's useful in military and civilian applications. The limitation of the batteries of sensor nodes necessitates that the energy efficiency is a key issue in WSN. We proposed a novel protocol LEACH-L based on the geographical location of nodes, which improves the LEACH on its clustering...
