Problems solved by technology
However, this time slot allocation method is based on the same business importance. When the data volume of sensor nodes changes dynamically, there is a risk that some sensor nodes cannot allocate time slots on time, and the utilization rate of time slots is low.
[0004] In order to solve the above problems, dynamic time slot allocation methods based on neighbor time slot exchange are widely used, such as Adjacent Timeslot Handoff-TDMA and Swap Wireless Access Protocol-TDMA. The dynamic time slot transfer method only realizes the transfer of time slots from rich nodes to nodes with insufficient time slots, without considering the priority of system business; when the sensor node's time slot demand is greater than the total number of time slots provided by the sink node, there is no time slot for rich nodes , and it is necessary to ensure reliable transmission of high-priority services, this dynamic time slot allocation method cannot achieve effective allocation of time slots

The invention relates to a wireless sensor network data acquisition method for dynamically adjusting a transmission time slot based on a service priority, and the method comprises the steps: enabling a sensor node in a wireless sensor network to set the service priority according to the importance degree of a service, and flexibly adjusting the service priority according to the data size of the node and the change of an acquisition service, and the aggregation node dynamically adjusts the service transmission time slot of the sensor node according to the change of the service priority so as to ensure that data with high service priority is transmitted preferentially. According to the method for dynamically adjusting the transmission time slot based on the service priority, reasonable utilization of the transmission time slot can be promoted, and reliable transmission of high-priority data is ensured.
Description
