Comparison of Incentive-Based Cooperation Strategies for Hybrid Networks

Abstract

Abstract. Today's public Wireless LANs are restricted to hotspots. With the current technology, providers can only target a small audience and in turn charge high prices for their service to generate revenue. Also, providers can not react appropriate to dynamic changes of the demand. With multi-hop cellular networks the coverage area can be increased and the installation costs and investment risks for the provider can be reduced. However, the individual customers play an important role in such networks and their participation must be encouraged. Therefore, we propose a cooperation and accounting scheme which introduces monetary rewards. We compare our scheme called CASHnet with the Nuglet scheme using simulations under the criteria of network liveliness as well as goodput, overhead and packet error rate.

Dynamic reputation-based incentive mechanism considering heterogeneous networks

“…Nuglets [24]- [26] and CASHnet [27] used a virtual currency to stimulate cooperation in decentralized pricing-based incentive schemes. A proposed pricing-based scheme called Sprite [28] used a central trust authority that determines the charges and credit for each node.…”

Routing game in hybrid wireless mesh networks with selfish mesh clients

“…However, the amount of charging or rewarding is also decided as a fixed rate. Weyland, Staub and Braun (2005) also proposed incentive-based schemes called CASHnet in which the payment or reward is based on the distance to the gateway. Not all these charging/rewarding methods are truthful for selfish participants.…”
