description The invention relates to a conflict-free transmission method of a sensor network, which comprises the following steps that: the working period of a coordinator is divided into a time slot sequence which consists of continuous time slots, the time slots in the time slot sequence are numbered and a number sequence which consists of the numbers of the time slots is periodic; the coordinator which works in the time slots in the time slot sequence is virtualized to be virtual coordinators corresponding to the time slots and the time slots with the same number correspond to the same virtual coordinator; general nodes connect with the virtual coordinators; the general nodes send guard time slot allocation requests to the virtual coordinators; the virtual coordinators transmit reply information to the general nodes according to the guard time slot allocation requests; and the general nodes transmit data to the virtual coordinators according to the reply information.
