In the case of the restrictions of energy on wireless sensor nodes,how to choose a reasonable routing protocol of adaptive topology change and control transmission radius effectively to improve the whole performance of the sensor networks becomes the issue on current research fields.Based on RSSI ranging technology,this novel introduced and compared three transmission distance control strategies,which utilizes time-delay and energy-comsumption as the reference index.Simulation results show that,choosing transmission radius dynamically can obviously improve the whole performance of the system,prolong the lifetime of the network and decrease the energy consumption and time delay of the sensor nodes.
