Network channel access protocol - interference and load adaptive

A network channel access protocol is indicated. Furthermore, specifically it is adapted for load, interference is avoided, and the distributed local determination channel access protocol which controls access to the share channel set by a node group is indicated. Share channel space is divided to the communication slot of a large number repeated with a predetermined time interval. The permission which uses a slot in order to communicate between all two nodes is dynamically adjusted with a channel access protocol. In order that a channel access protocol may be local, may presume the load to a (i) neighboring node, may be adapted for (ii) load and may avoid interference, it assigns use of a slot, or cancels assignment, and forces and announces use of a slot publicly in the interference area about (iii) itself.
