In this paper, the problem of end-to-end weighted max-min fair rate assignment in a two-channel multi-hop CDMA wireless access network is discussed. We show that end-to-end endweighted global max-min fairness (hierarchical as well as flow-based) can be achieved by simple extension of mac-layer fairness. In particular, we show that weighted end-to-end flow-based as well as hierarchical global max-min fairness can be simply insured if and only if weighted mac-layer max-min and weighted transport-layer max-min fair rates are achieved. The same results can easily be shown to be valid for more general wireless networks, which will be briefly discussed in this paper as well. In addition, we discuss a mac-layer algorithm, MAC-G G algorithm, that, with careful choice of parameters, not only provides weighted ¿-proportional fairness at the mac layer, but also leads to end-to-end weighted global max-min fairness (both flow-based and hierarchical) with an appropriate higher-layer protocol (i.e. weighted transport-layer max-min fair protocol).
