This paper is on the background of the applied communications of automated vehicle in the multi-hop environment. The paper provides a dynamic time-slot assignment protocol for the ground wireless sensor network (WSN), based on TDMA. By interacting of the two-hop neighboring nodes information, the protocol finishes the dynamic time-slot assignment, realizes the efficient and fair sharing of channel, reduces the transfer delay of the end-to-end burst data, meets the communication demand of assignment on-demand in WSN, and prolongs the life-time of the network with the virtual backbone mechanism. The theoretical analysis and simulation results showed that the protocol provided has better adaptability for the burst network services and topological variation, comparing to the traditional static mac layer protocol in the TDMA system.
