For the problem of long video transmission delay and low nerwork efficiency caused by high energy consumption, A DP-MDP (Dynamic Programming & Markov Decision Processes) video transmission scheme is proposed. The scheme take advantage of that the user instant request is independent to the past states and combine the DP algorithm with MDP to resolve related problem of the user request process, so it can significantly reduce the server and backbone network transmission loss of hot video, then improve the network efficiency. The theoretical analysis and derivation based an DP algorithm are conducted to the entire transmission process, then we establish the analytical expression based on DP algorithm. The simulation results show that compare to conventional video transmission, the video transmission program based on the DP-MDP can effectively save total energy and reduce the system transmission delay.DOI : http://dx.doi.org/10.11591/telkomnika.v12i3.4138
