F-DARA Algorithm For Time Slot Allocation In Internet of Things

In multi-user wireless video transmission over Internet of Things, to ensure that all video senders have
sufficient transmission opportunity before their deadline expire is a challenging and key issue. Thus fuzzy
based delay aware resource allocation (F-DARA) algorithm is proposed in this paper. This algorithm solves
the problem without assuming detail packet level knowledge. Instead, transmission delay deadlines of each
sender’s video packets are converted into linearly decreasing weight distribution within the considered time
period. Non-stationary slot allocation method is a unique characteristic of F-DARA algorithm which
depends on the allocation of previous slots. This is different from all existing slot allocation policies such as
round-robin or rate-adaptive round-robin policies, which are stationary because the allocation of the
current slot does not depend on the allocation of previous slots.
