A Hybrid Fault-Tolerant Routing based on Gaussian Network for Wireless Sensor Network
Dung Nguyen Quoc,Niansheng Liu,Donghui Guo 한국통신학회 2022 Journal of communications and networks Vol.24 No.1
In this paper, we have proposed a hybrid faulttolerantrouting to solve fault-tolerant issue in wireless sensornetworks (WSNs) based on hierarchical topology. The hierarchicaltopology is a combination of clustering and the labeling ofsensor nodes as Gaussian integers. Accordingly, the network areais divided into small square grids, the cluster head of each gridis represented by a Gaussian integer. These cluster heads areconnected together to create a Gaussian network. Through nodesymmetry, and the shortest distance in the Gaussian network,as well as the advantages of multi-path routing, this paperproposes a hybrid fault-tolerant clustering routing protocol basedon Gaussian network for wireless sensor network (FCGW). Thepurpose of FCGW is to improve fault tolerance, increase datareliability and reduce energy consumption for wireless sensornetworks. The experimental results of the proposed scheme showthat FCGW protocol has high data reliability. In addition, theFCGW protocol consumes about 48% of the energy in thenetwork, while other protocols consume 70% more energy.
