Abstract:
A communication apparatus in wireless sensor network and a method thereof are provided to remove instability of a network, thereby improving stabilization of a sensor network. If a connection setting failure report message is received from an error generating bridge system, a search unit searches a newly used channel and a bridge system(240) performing channel switching. An information management unit replaces information about sensor nodes(210) connected to the searched bridge system with information about sensor nodes newly connected to the searched bridge system through a channel.
Abstract:
PURPOSE: A farm management method and system therefor are provided to execute an inner actuator of a farm by determining the simultaneous execution of other actuator. CONSTITUTION: In case an execution mode of an actuator is automatic mode, a control apparatus determines the existence of an actuator which is need to be simultaneously executed with corresponding actuator(S303,S305). In case the simultaneous execution target actuator is not existed, the control apparatus determines the existence of an execution target actuator according to the received external environment conditions(S306). The execution target actuator is not existed, the control apparatus determines the existence of the actuator which is need to be executed in current time(S307).
