Efficient admission control algorithm for IEEE 802.11ad MAC handles isochronous and asynchronous traffic effectively.
Kivonat
The content discusses the importance of admission control in IEEE 802.11ad systems due to the availability of large bandwidth in the 60 GHz band. It introduces an admission control algorithm, EACIAR, that addresses isochronous and asynchronous traffic without assuming periodicity for asynchronous requests. The algorithm ensures linear runtime complexity while allocating resources proportionally fair. By maintaining a table for each request and following a detailed scheduling process, it guarantees SP allocation before deadlines. The article compares the proposed algorithm with related works and highlights its efficiency in handling various traffic types.
Statisztikák
IEEE 802.11ad supports two types of SP user traffic: isochronous and asynchronous.
The Traffic Specification (TSpec) element carries traffic parameters like Allocation Period (P), Minimum Allocation (Cmin), and Maximum Allocation (Cmax).
EACIAR algorithm has a linear runtime complexity.
For ISO requests, Ci is the duration of the task, and Pi is the period as well as the deadline of the task.
Dmax represents the maximum current deadline of all ASYNC requests.
