This paper presents a new call admission control (CAC) algorithm that takes into account the effect of mobility of users and adaptive modulation and coding (AMC) scheme, which can be used in orthogonal frequency division multiple access (OFDMA) systems with link adaptation. When the cell is decomposed into several concentric circles, time-frequency resources required for various traffics can be determined accurately, while resources reserved for handoff and AMC mode changed calls/connections or… CONTINUE READING
