| Summary: | A congestion control mechanism based on data delivery probability (CCM-DP) was proposed to work out the decline of data delivery performance on account of data congestion in delay tolerant networks (DTN) network coding-based data dissemination process.Considering the node mobility model,data delivery probability and data congestion degree,the data delivery probability model was constructed,and the congestion control mechanism was designed from two aspects,on the one hand,by the means of adjusting the packet forwarding process,it equilibriums the data packet delivery to avoid node congestion caused by too many packets received; and on the other hand,through the design of efficient discarding strategy,it reduces the impact of packet loss caused by data congestion.Ultimately,it was put into use in data dissemination process and some simulations were taken,the simulation results show that,CCM-DP can improve data delivery performance in data congestion environment. |
