Congestion control mechanism based on data delivery probability in DTN data dissemination network by Yi XIA, Guang-hong DENG

“…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.…”

Linear precoding for interference suppression in multi-cell multi-user TDD MIMO downlink by Zu-jun LIU, Jie-ling WANG, De-chun SUN, Ke-chu YI

“…To suppress multi-user interference (MUI) and inter-cell interference (ICI) existing in multi-cell multi-user TDD MIMO downlink,an interference suppression algorithm through designing precoder was proposed.Firstly,a precoding matrix was designed for MUI suppression,with the help of the QR decomposition of generalized MMSE channel inversion.And then the second precoding matrix was designed to suppress ICI and residual MUI,using a signal leakage criterion.The proposed algorithm could utilize TDD MIMO channel reciprocity,and thus did not require users' feedback information.The algorithm had been simulated in a multi-user TDD MIMO system composed of urban micro-cells.Simulation results show that,the proposed algorithm can effectively improve system capacity and user's average SINR.…”
