“…The connection is not unexpected given the fact that both our approach and [13] use the same utility functions to achieve fairness. However, unlike those approaches, which find longterm fair rates, our algorithm can find either long-term or short-term fair rates.…”

“…For ǫ = 1/2, the algorithm is similar to the procedures proposed for single channel, single-hop, TDMA networks [13] and for conventional single-hop OFDMA networks [14]. The connection is not unexpected given the fact that both our approach and [13] use the same utility functions to achieve fairness.…”

“…This ensures that A i [t] remains roughly constant over time under stationary channel conditions. Under reasonably general conditions, PF maximizes the sum of the logarithms of per-AT throughput [11] when the channel conditions of ATs are independent. Moreover, if their channel conditions are identically distributed, PF ensures that all ATs are allocated equal number of slots in the long term.…”

“…Obviously, the performance of the considered system not only depends on node cooperation, it also depends on the metric used to select the (m, r) pair. Originally from Kelly's work [15], the proportionally fair scheduling (PFS) algorithm [16][17][18][19][20][21] has spurred the development of a large number of network utility maximization (NUM) algorithms since 1997 [22][23][24][25][26], and is implemented in current 3G networks [27] as the most-cited NUM method. Being a promising scheme for fair resource allocation, PFS has shown excellent balance between throughput and fairness via multi-user diversity and game-theoretic equilibrium.…”
