Comparing RT-WiFi and HCCA approaches to handle real-time traffic in open communication environments |
Abstract | ||
|---|---|---|
In this paper we make a comparative assessment between the RT-WiFi and HCCA approaches to handle realtime traffic in IEEE 802.11 networks operating in open communication environments. The main focus will be on the assessment of the admission control mechanism proposed for the RT-WiFi upper layer, that is based on a non-preemptive EDF scheduling algorithm combined with a mechanism that measures the blockage times on medium access of real-time stations due to retransmissions and delays. The goal is to achieve a good compromise between medium utilization and timeliness. This proposal is compared with HCCA, and the results show that RT-WiFi offers a significantly better behavior in what concerns the maximum number of admitted streams. |
