中文摘要	A method for two-stage packet aggregation facing wireless sensor network with hybrid topology structure includes: building various nodes in a wireless sensor network into a hybrid topology structure which combines the star topology and mesh topology establishing a two-stage packet aggregation architecture for periodic sensor data based on the above described topology structure determining the packet format, aggregating and disaggregating the two-stage packets based on the topology structure and aggregation architecture according to the application, the aggregated nodes in the network configuring router nodes and aggregation attributes of the nodes according to the aggregation attribute, the sensor nodes performing the first-stage aggregation and generates an first-stage aggregation packet according to the aggregation attributes, the router node implementing second-stage aggregation and generating a second-stage aggregation packet the aggregation nodes taking charge of disaggregating the aggregated packets. The present invention adopts the above described hybrid topology structure, designs a two-stage packet aggregation method, decreases the overhead of packet-head, reduces the energy consumption of the nodes and inter-node interference, and saves communication resources.
