Delay Model for Saturated IEEE 802.16 Networks

Hai L. Vu, Sammy Chan
2008 2008 New Technologies, Mobility and Security  
In this paper, we propose an analytical model to evaluate the average packet delay and its standard deviation in a saturated IEEE 802.16 network.  ...  unsaturated networks. 978-2-9532443-0-4  ...  The delay of the random access protocol specified in the IEEE 802.16 standard was investigated in [8] for a saturated network using Markov models.  ...

Voice quality framework for VoIP over WLANs

Md. Atiur Rahman Siddique
In conjunction to network performance, we also incorporate the characteristics of voice codecs and dejitter buffer. We identify that the delay and loss in the queue degrade [...]  ...  In this thesis, we model the voice capacity of the DCF and PCF based WLANs with a special attention to the voice quality to assist in network design and planning.  ...  A number of works in the literature investigated the performance of the IEEE 802.11 networks which is of great essence in order to analyze the voice performance of VoIP in such networks.  ...
