In a wireless ad hoc network, packets are sent from node-to-node in a multihop fashion until they reach the destination. In this paper we investigate the capacity of a wireless ad hoc network in supporting packet video transport. The ad hoc network consists of n homogeneous video users with each of them also serving as a relay node for other users. We investigate how the time delay affects the video throughput in such an ad hoc network and how to provide a time-delay bounded packet video delivery service over such a network? The analytical results indicate that appropriate joint admission and power control have to be employed in order to efficiently utilize the network capacity while operating under the delay constraint as the distance between source and destination changes.
