Abstract

The bandwidth allocation in IEEE 802.11 is defined as assigning two-dimensional blocks in time and frequency domain (which are called Bursts) to users. Resource allocation is vital for system efficiency; however, the detail is not defined in the standard and left open to the implementer. Many algorithms have been proposed for this purpose in OFDMA-based networks. In this paper, a GENETIC ALGORITHM for BURST CONSTRUCTION in WiMAX networks is proposed which adheres to rectangular structure of DOWNLINK frames in IEEE 802.16 standard. In the proposed GENETIC ALGORITHM, user requests with specific area are mapped to chromosomes. After passing the evolution stages, an optimized burst allocation is obtained for the requests in terms of shape and position. The goal of the proposed GENETIC ALGORITHM is to locate maximum number of bursts in the frame such that, wasted space is minimized. Simulation results confirm that, our proposed algorithm can produce a near-to-optimal solution by means of an Iterative search.
