Random access scheme
WebbThe proposed random access technique works in the following way: as soon as a user has a packet available for transmission, the first instance is sent in the next available slot while the other l 1 copies for the same packet are placed in the next N swN1 slots with equally distributed probability. N WebbA variety of counter-based broadcast schemes have been proposed to mitigate the broadcast-storm problems, using the count threshold value and a random access delay. …

WebbInternet of Drones (IoD), designed to coordinate the access of unmanned aerial vehicles (UAVs), is a specific application of the Internet of Things (IoT). Drones are used to control airspace and offer services such as rescue, traffic surveillance, environmental monitoring, delivery and so on. However, IoD continues to suffer from privacy and security issues. … Webb• Non-persistent CSMA: if medium idle, transmit; otherwise wait a random time before re-trying. – Thus, station does not continuously sense channel when it is in use. • P-persistent: when channel idle detected, transmits packet in the first slot with p. – Slotted channel, i.e., with probability q = p-1, defers to next slot. 96
