In this paper we present results of evaluating and validating the three novel measurement based admission control algorithms for WiMAX dealing with connection requests that arrive in batches (ARAC, nscARAC, EMAC). We focus on the capacity of a future 4G system using non binary LDPC codes. Simulations rely solely on the use of VoIP traffic flows (with and without voice detection). In order to avoid actual FEC decoder implementation we use L2S interface described in IEEE 802.16 EMD. We use performance metrics characteristic to admission control to assess the system performance. Simulated nodes move according to the Leavy Walk distribution. All algorithms presented in the paper have been simulated using the ns2 platform with ViMACCS extension developed by authors as part of previous work.
