This project will explore the role of barter-exchange incentives for cooperation in wireless networks. While cooperative wireless techniques show great promise, they also assume a degree of trust and a form of "selfless" behavior that may not be realistic. Cooperating terminals will accrue benefits, but they will also incur costs (wasted battery energy being an obvious example). Over time, benefits might logically be expected to exceed costs for most participants, but in the short term there will be winners and losers, and we cannot realistically assume that enlightened self-interest will prevail. The sizable literature on incentive mechanisms for wireless networks has emphasized abstract mechanisms in which nodes receive some form of credit for helping other nodes. These prior efforts often mimic the operation of a complex economy. In doing so, they illustrate the difficulties inherent in this approach. The efficient operation of a complex economy requires such enablers as a stable currency, a system of credit and credit-worthiness, a shared understanding of what things are worth, and a good deal of record keeping. It may be that this complexity is not warranted here, and that a simpler approach, based on the mechanisms of barter and exchange, can provide the necessary incentives for the degree of cooperation we require.In this project, we propose to explore the roles and limitations of barter-exchange incentive mechanisms for wireless networks. The specific research tasks include mechanisms for inducing cooperation between nodes by exchange of bandwidth, network connectivity, and content. The barter-exchange mechanisms proposed here provide a means to compensate terminals for temporal inequities in benefits and costs. Further, they also provide a mechanism by which cognitive radios can organize themselves into networks and/or operate efficiently in shared spectrums. The research proposed here is of great relevance to the anticipated deployment of cognitive radio networks including those planned for the wireless subnets of the GENI facility. The proposed educational supplement to the research activities here will also train graduate students in cooperative communications, an area of emerging interest in wireless data communications.

该项目将探讨易货交换激励对于无线网络合作的作用。虽然协作无线技术显示出巨大的前景，但它们也假设了一定程度的信任和一种可能不现实的“无私”行为形式。 合作终端会带来好处，但也会产生成本（浪费电池能量就是一个明显的例子）。随着时间的推移，从逻辑上讲，大多数参与者的收益可能会超过成本，但短期内就会有赢家和输家，我们不能现实地假设开明的自身利益将会占上风。关于无线网络激励机制的大量文献都强调抽象机制，在这种机制中，节点因帮助其他节点而获得某种形式的信用。这些先前的努力通常模仿复杂经济的运作。通过这样做，他们说明了这种方法固有的困难。复杂经济的有效运作需要稳定的货币、信用和信誉体系、对事物价值的共同理解以及大量记录保存等推动因素。也许这种复杂性在这里是不必要的，基于易货和交换机制的更简单的方法可以为我们所需的合作程度提供必要的激励。在这个项目中，我们建议探索角色和无线网络易货交换激励机制的局限性。具体的研究任务包括通过交换带宽、网络连接和内容来诱导节点之间合作的机制。这里提出的易货交换机制提供了一种补偿终端在利益和成本方面暂时不平等的方法。此外，它们还提供了一种机制，认知无线电可以通过该机制将自身组织成网络和/或在共享频谱中高效运行。这里提出的研究与认知无线电网络的预期部署密切相关，包括为 GENI 设施的无线子网规划的网络。拟议的研究活动的教育补充还将培训研究生合作通信，这是无线数据通信中新兴的兴趣领域。
