This paper presents a new metric, Expected Data Rate (EDR), for accurately finding high-throughput paths in multihop ad hoc wireless networks. The metric is based upon a new model for transmission interference which is a critical factor in determining path throughput. This paper constructs a realistic and practical transmission interference model by determining transmission contention degree of each link as a function of the wireless link loss; quantifying the impact of the wireless link loss on medium access bakeoffs; and considering possible concurrent transmissions when two links do not interfere with each other. The transmission interference model also takes the non-optimality of IEEE 802.11 medium access scheduling into account.
