Aimed at issues of network note premature death and short network life cycle exposed in civil aviation airport lounge bridge monitoring network for field testing at the airport an improved LEACH algorithm based on remaining energy and location is presented

consider nodes remaining energy average remaining energy of network and node location according to network environment factor

select the optimal cluster head in two steps

at the same time

use energy consumption estimation method to determine average remaining energy of network to balance network energy consumption can prolong lifetime of WSNs.Modeling and simulation on civil aviation airport lounge bridge monitoring management system by Matlab

results show that improved LEACH algorithm performs better than original routing layer LEACH algorithm in balance network energy consumption

prolong lifetime of WSNs.
