Currency boosts content dissemination in noncooperative ad-hoc networks

In most of research works on the wireless ad-hoc network, it is often assumed that all nodes in the network are cooperative to relay packets. However, it is natural for nodes to be reluctant to cooperate by force due to the consumption of resources. Thus, a concept of noncooperative ad-hoc networks is being widely accepted in the latest research works. For the noncooperative ad-hoc networks, a framework which stimulates nodes to mutually cooperate was proposed by W. Yuen. It was shown that the framework utilizes more net capacity of the network than the multi-hop cooperative ad-hoc network does by exploiting data diversity and eliminating redundant bandwidth wastes for the multi-hop packet relays. In this paper, we suggest a content dissemination protocol which adopts currency and we show that adopting currency outperforms the previously proposed one through extensive simulations
