F-DARAAlgorithm forTime 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
