Submarine WSN node energy consumption control algorithm considering ship dynamic position
Due to the lack of continuous and stable power supply in the seabed environment,sensor nodes usually rely on limited internal energy,and the dynamic location of ships on the seabed makes the node density layout more complex,resulting in unbalanced energy consumption of WSN nodes.Therefore,an energy consumption control algorithm for submar-ine WSN nodes considering ship dynamic position is proposed.The submarine WSN structure model is established,and the ship trajectory is predicted by polynomial Kalman filter.The submarine WSN cluster structure is divided,the number of nodes in each cluster is dynamically adjusted,the density of submarine WSN nodes is controlled,the energy consumption model of dynamic change of ship position is established,the energy consumption demand of each cluster node in different time periods is estimated,and the energy consumption of WSN nodes is balanced,so as to achieve node energy consumption control.Experimental results show that the proposed algorithm effectively balances node energy consumption,maintains connectivity and coverage,improves the overall performance of subsea WSN,and has a longer stable running time and a stable growth of failed nodes.
