Adaptive Resource Allocation Algorithm in Wireless Access Network
Abstract: Wireless network
state varies with the surrounding environment, however, the existing resourceallocation
algorithm cannot adapt to the varying network state, which results to the
underutilization of frequency and power resource. Therefore, in this paper, we
propose an adaptive resource allocation algorithm which can efficiently adapt
to the varying network state by building an optimal mathematical model and then
changing the weighted value of the objective function. Furthermore, the optimal
allocation of subcarrier and power is derived by using the Lagrange dual
decomposition and the subgradient method. Simulation results show that the
proposed algorithm can adaptively allocate the resource to the users according to
the varying user density which represents the network state.
