Optimal choice of FEC parameters to protect against queueing losses in wireless networks

This paper proposes algorithms to determine an optimal choice of the FEC parameters (n, k) to mitigate against the effects of packet loss due to buffer overflow at a wireless base station on multimedia traffic. To solve this problem, we develop analytic models of the considered network scenarios that take into account traffic the arrival rates, the channel loss characteristics, and the size of the buffer at the wireless base station. We develop an iterative procedure to compute the packet loss probabilities after FEC recovery and verify the analytical results via simulation.
