A Proposal Approach for Load Distribution and Resources Sharing in IEEE 802.11 Networks
Résumé
Recently there is a growing interest in the internet and multimedia wirless networking where the bandwidth and the QoS metrics must profoundly adjusted to the application requirement. However the problem of user bandwidth availability arises as one of the most limit of this solution. In fact, the IEEE 802.11 standards do not provide performed mechanism of loading distribution among different APs of the network. Then an AP can be heavily overloaded leading to station throughput degradation. This paper focuses on the specification of a centralization solution for QoS management in IEEE 802.11 networks. It, mainly, presents the general architecture of the overall system based on a load balancing server over the AP(s) network resources. In addition, the paper addresses a protocol specification for AP and mobiles interactions intended to provide best resources allocation and efficiency on communication metrics. This protocol is being described and simulated with SDL and MSC tools as a first step before experimentation in real environment.
