To solve the problem of the efficient transmission in error-prone wireless network and unfairness attribute to retransmission. Inspired by the network coding

a transmission model based on coding group （TCG） was proposed. Because of the different type of packets of central station

this model also could be divided into internal transmission model （LTCG） and external transmission model （ETCG）. Furthermore

a transmission framework based on coding group （FTCG） was introduced as to the above model. At last

through the simulation

the transmission delay and throughput of the unicast strategy and FTCG separately were analyzed and compared. Moreover

under the condition of nodes’ burst error

the influence of the unicast strategy and retransmission based FTCG was proposed and analyzed. Simulation results show that FTCG can improve the transmission efficiency and solve the sharp decrement of performance with the condition of nodes’ burst error. FTCG can keep the transmission fairness of the different data.
