Method for transmitting data by several users to receiver, involves sending data using slotted ALOHA protocol, and setting cluster head for coordinating data transmission between users, to avoid collision between users of same cluster

摘要

The data is transmitted by the users (10b-10e) to the receiver, using the slotted ALOHA protocol. The users in the cluster (10) are divided, in which the cluster is comprised of several users who are able to communicate with each other. Each cluster has a cluster head (10a) which coordinates the data transmission between the users, so that collisions between users of the same cluster is avoided at the receiver, during data transmission by the users via common communication channel, while avoiding collisions occurring between data packets from users who belong to different clusters.
