We consider the throughput/delay tradeoffs for scheduling data transmissions in a mobile ad-hoc network.To reduce delays in the network, each user sends redundant packets along multiple paths to the destination.Assuming the network has a cell partitioned structure and users move according to a simplified iid mobility model, we compute the exact network capacity and the exact end-to-end queuing delay when no redundancy is used.The capacity achieving algorithm is a modified version of the Grossglauser-Tse 2-hop relay algorithm and provides O(N) delay (where N is the number of users). We then show that redundancy cannot increase capacity, but can significantly improve delay.The following necessary tradeoff is established: delay/rate 驴 O(N).Two protocols which use redundancy and operate near the boundary of this curve are developed, with delays of O(\sqrt {\text{N}}) and O(log(N)), respectively. Networks with non-iid mobility are also considered and shown through simulation to closely match the performance of iid systems in the O(\sqrt {\text{N}}) delay regime.
