Taking into account both packet collision and backoff interval, we evaluate performance of probabilistic flooding in terms of temporal growth of the delivery ratio and the energy efficiency by computer simulation. Slotted ALOHA-type broadcast protocol is supposed and a node inserts random backoff interval based on its own current contention window value, prior to packet forwarding. Packets collide at a receiving node, when they are transmitted simultaneously. However, we consider no retransmission mechanism. Numerical results show that large contention window value results in not only slow growth of the delivery ratio but also slight improvement of the energy efficiency. However, the final delivery ratio and the ratio of collision reception can be improved by increasing the contention window value. It is also revealed that temporal behavior of the delivery ratio mainly depends on the product of the node density and the forwarding probability.
