A hybrid CAC algorithm for maximizing downlink capacity of M-WiMAX systems

Abstract: Due to the implementation of an Adaptive Modulation-Coding (AMC) mechanism in the 802.16e physical layer, each connection's bandwidth requirements cannot be statically computed, but they derive as a function of the terminals' instantaneous Signal-to-Noise Ratio (SNR). Therefore, the Connection Admission Control (CAC) mechanism fails to establish an efficient policy that would optimally exploit the system's resources. In this respect, the present paper formulates initially an adequate method for statistically c… Show more

“…Thus, parameters and the algorithm for estimating the network traffic and the strategy of CAC decision are key point of CAC. At present, most proposed CAC technologies for Wi-MAX networks [3]- [10] use the classical Poisson process to describe the network traffic and focus on the design and optimization of decision strategy. While they ignored the effect that the network traffic model has a great impact on CAC decision.…”
