wireless sensor networks( WSNs) technology is used to collect data by aircraft prognostics and health management( PHM) system. The requirements of high real-time on information transmission for aircraft PHM
should shorten the network average path length by power control to optimize network topology. A power control algorithm based on small world theory( PCS) is proposed
the algorithm shortens network average path length by the means of adding short-cuts
and it uses genetic algorithm to optimize the shortcuts
so optimization network which has less communication cost and shorter network average path length can be obtained. The simulation results show that the PCS algorithm optimizes network topology
shortens network average path length and improves information transmission rate.
