Dynamic sectorisation based on genetic algorithms for OFDMA networks

OFDMA is the multiple access technique proposed for future communication systems. With growing demands for high data rates radio resource management is an important aspect for OFDMA systems. Sectorisation is one such radio resource management technique that has been proposed as an efficient scheme to improve system performance for GSM, CDMA and OFDMA systems. In this paper, a dynamic sectorisation method based on using a Genetic Algorithm (GA) for OFDMA networks is designed and verified by simulation. The algorithm proposed in this paper can give up to 50% enhancement of system throughput in OFDMA networks for heavily loaded and unbalanced traffic scenarios.
