Debt based mechanism to stimulate cooperation in Ad hoc networks
Ad hoc网络的基于债务关系的合作激励机制

The incentive mechanism for cooperation is a decisive fact to extend the application of Ad hoc networks. But in networks with insufficient resource the cost of incentive mechanism must be restricted. In the application of file sharing, this paper proposed an incentive mechanism called SDE. Since only concerns direct interaction information, SDE was easy to be implemented in distributed way. SDE could also avoid the cheat behavior and the attack behavior of global reputation schemes and the problem of the fake of money within virtual currency schemes. By constructing repeat games among nodes, the nodes were willing to maintain the availability of debt relationships spontaneously. It proposed a routing algorithm in debt networks called M-PGA which can match the dynamic by adopting the idea of local routing and improve the routing performance by routing selection based on best path.
