Other AbstractThe invention relates to a mixed topological structured wireless sensor network-oriented two-grade packet aggregation method. The method comprises the following steps that: various nodes in a wireless sensor network are constructed to form a net and star mixed topological structure based on the topological structure, a two-grade packet aggregation structure is established for periodical sensor data based on the topological structure and the aggregation structure, a packet format is determined and two-grade packet aggregation and disaggregation are performed a sink node in the network configures a routing node and an aggregation attribute on the routing node according to application according to the aggregation attribute, a sensor node performs first-grade aggregation to generate a first-grade aggregated packet according to the aggregation attribute, the routing node performs second-grade aggregation to generate a second-grade aggregated packet and the sink node is used for disaggregating the aggregated packets. The net and start mixed topological structure is adopted, and the two-grade packet aggregation method is designed, so that the communication times, the expense of a packet header, the energy consumption of the nodes and the interference among the nodes are lowered, and communication resources are saved.
