Abstract：In the design and layout of Wireless Sensor Networks (WSNs), multiple Sink node locating is the key step in network
topology. It is very important to control energy-consumption of network communication. By analyzing the layout of Sink node model,
an improved three chain hybrid genetic algorithm is proposed to solve the Sink node’s optimal location problem. The experimental
results show that compared with the enumeration algorithm, the three chain hybrid genetic algorithm for the Sink node has better
solutions and higher efficiency of the algorithm, which can reduce the energy consumption of wireless sensor networks and improve
the network performance.
