Data Fusion Technology Based on LEACH Protocol

doi:10.3969/j.issn.1006-2475.2017.10.006

Abstract

Abstract: In this paper, a multi-level data fusion scheme based on LEACH protocol (MLDA-LEACH) is proposed. According to the hierarchy of LEACH protocol, first of all, the clusters use Kalman filtering algorithm to acquire the source data filtering to remove noise; secondly, the cluster nodes use distribution graph method to treat raw data to improve data accuracy, and then the adaptive weighted algorithm is used to aggregate the effective data. Simulation results show that MLDA-LEACH can effectively reduce energy consumption and prolong the life cycle of wireless sensor networks.

Key words: LEACH, data fusion, Kalman filtering, distribution graph, adaptive weighted, sensor
