YANG Jia, LIU Xiaoli, XU Qiang. A new clustering routing protocol for heterogeneous WSNs[J]. 2020, (4): 121-124+128. DOI: 10.13873/J.1000-9787(2020)04-0121-04.
Aiming at the problem that the cluster head node is overloaded
the energy consumption of nearby nodes is unbalanced and the system robustness is poor in heterogeneous wireless sensor networks( WSNs)
a clustering routing algorithm based on dual cluster heads for heterogeneous WSNs is proposed. Firstly
the algorithm uses quantum optimization algorithm and particle swarm optimization( PSO) algorithm to construct a network model for dual cluster heads to solve the problem of node energy consumption. Then
optimize the primary and secondary cluster head fitness functions
so that the cluster head distribution is resonable and can improve the system robustness. Establish the weight of the cluster head and the base station side to construct a directed connectivity graph
use the minimum spanning tree for inter-cluster communication
reduce node energy consumption. The simulation results show that the algorithm effectively reduces the network energy consumption
