Abstract:

A energy-balanced clustering algorithm for WSN based on PSO (EBPSO) for uranium tailings storage nuclide monitoring has been proposed to extend the network lifespan of existing WSN. Firstly, in the cluster head(CH) election stage, the particle swarm optimization algorithm was used to select the most reasonable CH. Taking into account parameters such as sensor node energy, distance between CH and distance between CH and base stations, the most reasonable CH nodes were selected and applied to uranium tailings pond nuclide monitoring, thus forming a wireless sensor network. Secondly, at the data transmission stage, a technique for selecting forwarding nodes was proposed. Then, to reduce energy consumption, an energy threshold re-clustering strategy was applied. Finally, the performance of clustering routing algorithm based on PSO algorithm optimized fuzzy C-means (POFCA), low energy adaptive clustering hierarchy(LEACH), and energy-efficient unequal clustering(EEUC) method were compared. The simulation test results demonstrate that compared with POFCA, LEACH, and EEUC, the network lifetime of EBPSO algorithm is increased by 1.7%, 24.7% and 9.2% respectively. It successfully extends the network lifespan and is ideal for the application situation of uranium tailings pond nuclide monitoring.
