Abstract:
Successive interference cancellation (SIC) is a physical layer mechanism, which eases packet collisions. It can decode simultaneously transmitted packets from multiple stations with different transmitting power levels, and hence raises the throughput of wireless networks. In an earlier work, the optimal throughput of an IEEE 802.11 network with SIC for a given initial contention window ($W$) is investigated. In this paper, we suggest that an optimal $W$ can be chosen to further improve the optimal throughput. We re-visit the throughput optimization problem with $W$ being another degree of freedom, and propose an efficient way to obtain the optimal $W$ and the corresponding probability mass function of power levels. Numerical results have verified that the optimal throughput can be further increased by allowing $W$ to be an optimal variable.
