A Dynamic Frequency Allocation Scheme for IEEE 802.16 OFDMA-Based WMANs Using Hungary Algorithm
Emerging Directions in Embedded and Ubiquitous Computing
In IEEE 802.16 Wireless Metropolitan Area Networks (WMAN) with Orthogonal Frequency Division Multiple Access (OFDMA) physical layer, dynamic subchannel allocation algorithm (DSAA) is essential for a Base Station (BS) to efficiently utilize bandwidth capacity. Conventional DSAAs usually group all subcarriers into a number of subchannels and allocate subchannels to Subscriber Stations (SS), one for each SS, according to its traffic demand and channel quality of the link between BS. However, thedoi:10.1007/978-3-540-77090-9_19 dblp:conf/euc/SheuYC07 fatcat:wge7a4evkfevja2cw5qcm2bkoe
