This paper addresses the issue of wireless resource allocation of a Mobile WiMAX cell based on OFDMA access technique. We compare two strategies: the MAX SNR which is the most used channel assignment technique and our proposal which is based on channel condition learning. As we distinguish four IEEE 802.16e-2005 service classes: UGS, rtPS, nrtPS and ErtPS, we combine these strategies with a scheduler...
The increasing development of mobile applications has changed the traditional demands of computer networks, which must now provide ubiquitous broadband wireless communication. In this context, IEEE 802.16 standardizes the physical and medium access control layers of the technology, aiming to allow network access in both nomadic and mobile scenarios. In this work we analyze the impact caused by overhead...
