چكيده فارسي :
In this paper, we propose a channel and queue
aware cross-layer algorithm for allocating power and sub-carriers
to users in Orthogonal Frequency Division Multiple Access
(OFDMA) networks. Our algorithm uses utility to build a
bridge between the physical layer and upper layers and also
to balance the efficienc and fairness of the radio resource
allocation. The objective is to develop a method based on two
practical assumptions for allocating resources to users. The firs
assumption is the fact that the OFDMA system operates with
a limited No. of bit rates and the second one is the fact that
the users which are scheduled for transmission, may not have
enough data to transmit. We further study the performance
of the proposed algorithm through simulations. Comparisons
with similar approaches are also conducted which are indicated
significan performance improvement.
