Abstract
Bandwidth-delay product (BDP) and its upper bound (BDP-UB) have been well-understood in wireline networks such as the Internet. However, they have not been carefully studied in the multi-hop wireless ad hoc network (MANET) domain. In this paper, we show that the most significant difference of computing BDP and BDP-UB in MANET is the coupling of bandwidth and delay over a wireless link, where only one packet is allowed to be transmitted over the channel at a time. Based on this observation, we prove that BDP-UB of a path in MANET is upper bounded by is the number of round-trip hops of the path. We then further obtain two tighter bounds of BDP-UB, and verify them through ns-2 simulations.
