Deadline-aware Emergency Data Resource Allocation Control for IEEE 802.11ax

In the event of a natural disaster, congested wireless access points must transfer emergency messages within a waiting deadline for the starting time of message transmission. This paper proposes a scheduler for resource unit (RU) allocation in IEEE 802.11ax to meet the waiting deadline of emergency messages, such as crucial camera image data for understanding post-disaster situations. A simulation shows that the proposed scheduler is able to allocate the emergency messages in the RUs according to the waiting deadline.
