We propose a new channel rate and queue state adaptive time resource allocation heuristic for the base stations in a multiuser wireless access scenario. Motivation of the scheme is derived through the effective capacity concept. Our proposed strategy accounts for fairness and quality-of-service (QoS) of the system on per frame basis. Our results show that the proposed scheme benefits the users with...
Orthogonal frequency division multiplexing (OFDM) with dynamic scheduling and resource allocation is a key component of most emerging broadband wireless access networks such as WiMAX and LTE (long term evolution) for 3GPP. However, scheduling and resource allocation in an OFDM system is complicated, especially in the uplink due to two reasons: (i) the discrete nature of subchannel assignments, and...
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...
