To solve the problems of some studies have pointed out that for TCP-Veno at light load network environment can not use the bandwidth effectively,while under the heavy load network environment can not accurately distinguish between congestion loss and wireless random packet loss,which result in frequent congestion and other troubles.An improved algorithm called TCP Veno+ is proposed.Based on the statistic data of the congestion packet loss event and wireless random packet loss event in a certain period,the probability of the two different loss events are computed respectively.Then it is used to modify the loss differentiation algorithm of original TCP-Veno to improve the loss distinguishing accuracy.The simulation results show that the improved algorithm in heterogeneous wireless networks has good performance,fairness,and stabilityp.
