Cooperation in ad hoc networks cannot be taken for granted when
nodes belong to distinct authoritative domains. In this paper we present
Cashflow, a virtual currency system to motivate nodes to participate in ad hoc
networks and to prevent selfishness. This system is different to previously
proposed virtual currency systems in that it uses a channel concept for data
transmission as well as a market system for pricing. The combination of
channel and market concept results in a number of positive system
characteristics. For instance, Cashflow provides implicit access regulation and
load balancing mechanisms to avoid overload situations in the network.
Additionally it considers node context for data transmission and pricing.
Cashflow also leaves the decision about the participation degree to the user,
which is an important but frequently neglected topic for the user acceptance of
virtual currency systems.
