Abstract：A cooperative handover mechanism based on a Hierarchical Network Coding (HNC) is proposed for multi-hop, multi-path handover scenario in wireless internet of things in this paper. Based on traditional practical network coding, HNC makes use of the different hop between mobile terminal and network access point, and adopts multi intermediate circle to divide levels in the network. With the cooperation of intermediate nodes in different levels, mobile terminal can establish handover connection with remote access point. HNC keeps reliable handover connections during the terminal is moving.
