Nâng cao hiệu quả giao thức LEACH trong mạng cảm biến không dây

Abstract

In recent years, Wireless Sensor Network (WSN) has been researched and applied in many fields such as rescuing, environmental monitoring, and IoT applications, etc. Especially, when the power source is limited, maintaining the working status of the sensor nodes in the network becomes more and more important. In this article, we explore the operation of the LEACH (Low Energy Adaptive Clustering Hierarchy) protocol - a protocol compatible with low-energy sources and propose a solution to improve efficiency in wireless sensor networks. The simulation results show that our solution is better in terms of the number of packets reaching the base station and the average lifetime of the sensor nodes.
