Adaptive control method for WSN link based on interference estimation |
| |
| Abstract: | In view of problem that existing transmission power control algorithms of wireless sensor network do not take full account of actual channel interference,calculation method of optimal transmission power based on interference estimation was given.An adaptive rate adjustment algorithm was proposed in consideration of time-varying characteristics of communication channels and the number of active nodes. Finally feasibility of the proposed method was verified through experiments. |
