Abstract	We consider the problem of joint network coding and packet scheduling for multimedia transmission from the Access Point (AP) to multiple receivers in 802.11 networks. The state of receivers is described by a hidden Markov model and the AP acts as a decision maker which employs a partially observable Markov decision process (POMDP) to optimize the media transmission. Importantly, we introduce a simulation-based dynamic programming algorithm as a solution tool for our POMDP abstract. Our simulation-based algorithm simplifies the modeling process as well as reduces the computational complexity of the solution process. Our simulation results demonstrate that the proposed scheme provides higher performance than the network coding scheme without using optimization techniques and traditional retransmission scheme.
