Abstract	A new network transmission framework highlighting the concept of cross-layer co-design for packet loss reduction is presented in this article. The proposed framework takes into account the correlation between the packet loss rate and the packet size under a given channel condition, and assigns different tasks to layers involved: physical/ MAC layer for monitoring current channel statuses, IP layer for fragmentation, transport layer for bandwidth allocation, and application for the selection of coding method and compression rate. Our proposed scheme can detect current channel conditions and dynamically adjusts parameters in each layer to match the changing channel status. Especially, when a mobile node is conducting a handover process,the radio signals and channel conditions will change rapidly. The proposed scheme can accommodate the variation quickly and prepares adequate data for corresponding node in advance, so that we can reduce the handover delay and make seamless handover possible.
