Delay Limited Capacity of Ad hoc Networks: Asymptotically Optimal Transmission and Relaying Strategy
15 years 5 months ago
— The delay limited capacity of an ad hoc wireless network confined to a finite region is investigated. A transmission and relaying strategy making use of the nodes’ motion t...
