... collision and less idle wait- ing time in backoff procedure. In “Incomplete Game , access delay performance is far better than “NM”, and comparable with “IBM”, as it can easily adapt the variable game ... no collision and low waiting time in backoff procedure. For “Incomplete Game channel efficiency almost keep constant after 30 nodes, as each node can adapt to the variable game state...
