Abstract — Multiuser diversity has been shown to increase the throughput of mobile ad hoc wireless networks (MANET) when compared to fixed networks. We present a different multiuser diversity strategy for packet relaying, which permits more than one-copy (multi-copies) of a packet being received by relay nodes, thus allowing to decrease the delay on such networks for a fixed number of total users ¢. We show that the £¥¤§¦© ¨ throughput is preserved by our multi-copy technique when ¢ goes to infinity. In addition, we find that the average delay and variance scale like £¥¤�¢� ¨ and £¥¤�¢��� ¨ respectively for both one-copy and multi-copies techniques. We also show that for a fixed ¢ and by multi-copy forwarding, a maximum bounded delay value can be guaranteed. I
