Optimal Parameter Settings for Forward Error Correction Schemes for Multimedia Streaming over Wireless Networks

This paper investigates algorithms to determine an optimal choice of the FEC parameters (n, k) to mitigate the effects of packet loss due to buffer overflow at a wireless base station on multimedia traffic. We develop an analytic model of the considered network scenario that takes into account the traffic arrival rates, the channel loss characteristics, the size of the buffer at the wireless access point, and the influence of the FEC parameters on the packet loss. Applying the theory of recurrent linear equations, we present a new approach to establish a closed form solution of the underlying Markov model for the buffer occupancy and verify the analytical results via simulations
