Optimal Design of Wireless Sensor Network Topology Structure Based on Smart Home

Considering more sensors are used in the smart home, and redundancy exit in the traditional star-mesh hybrid structure of the sensor nodes, an improved wireless sensor network topology structure is proposed. The evolutionary game theory methods is used to optimize the hybrid structure.In this way,when the appropriate transmission distance is found,efficiency and robustness of data collection will be upgraded. And it is proved that it can effectively optimize the network topology structure to achieve reduced redundancy and power consumption by means of the simulation.
