Abstract: Data packet compression provides a simple and effective solution for the data aggregation of Wireless Sensor Network (WSN). Research was conducted on a data packet compression technology which was based on order coding. Two limitations were analyzed, which were too concentrated and too complex, and a new distributed coding by ordering algorithm (DCOA) was put forward. The new algorithm established a new implementation flow, designed a new mapping table data structure, reduced the complexity of implementation and balanced the energy load of the nodes through the distributed dynamic processing, and significantly increased the efficiency of data aggregation. The superiority of the algorithm is verified through simulation experiments.
