| Abstract: | The optimization of node distribution is studied to reduce the energy consumption and ensure the effective information acquisition in wireless sensor network.A precise mathematic definition is given to the control model covering a wireless sensor networks.According to the mobility of sensor nodes,an optimized distribution algorithm based on genetic algorithm is proposed,which,as shown in the simulation results,can not only optimize the node distribution in target area but reduce the network energy consumption and increase the whole coverage rate at a relatively low cost. |

| Keywords: | wireless sensor network mobile node network coverage rate network topology control genetic algorithm |
