Abstract:

Wireless LAN MAC protocols can hardly make a balance between diverse traffic requirements of multi-users and network throughput efficiency.A bandwidth allocation model with super-frames and an optimization goal with a penalty function was established.After calculating the m nimum bandwidth satisfying a single user's QoS requirement,traffic cognition bandwidth allocation algorithm (TCBAA) for multi-users was proposed.Analysis and simulations experiment show that TCBAA can satisfy more users' QoS requirements under limited bandwidth resources,compared with fixed bandwidth allocation and maximum throughput allocation.

Key words: MAC schedule, traffic cognition, QoS, bandwidth allocation
