Mandayam, NarayanRutgers Univ New BrunswickCooperation and Conflict: Coalitional Games in Spectrum SharingCooperative communication techniques hold the promise of promoting efficient spectrum sharing and a good deal of important research has studied approaches such as collaborative signal processing, cooperative coding, relaying and forwarding. What is perhaps less generally considered in research studies is that cooperation may involve significant costs, and that the greatest immediate benefits will not necessarily go to the users that bear the greatest immediate cost. For example, cooperation may require that a terminal delay its own transmissions and use its limited energy budget to relay messages for other terminals. Moreover, even if there were no added cost in terms of energy or delay, the rules by which the benefit is distributed may create yet another type of disincentive to cooperation. Thus, even in the absence of any transaction costs for cooperation, the aggregate benefits of user cooperation can only be realized through techniques that provide adequate incentives to each user, and for each transaction.This project is using coalitional game theory as a framework to provide significant insight into the dynamics of cooperative communications as well as the incentives through which such cooperation might be achieved. Integrating models from game theory with communications and information theory, the cooperation mechanisms being studied are: (1) coalitions in receiver cooperation, (2) coalitions in transmitter cooperation, and (3) incentives and costs in coalition formation. This project is contributing to the knowledge and technology of coalition formation that can result in improved spectrum sharing in cognitive radio networks. An educational supplement to the theoretical research activities is using the ORBIT Testbed for evaluating simple practical coalition formation mechanisms.

Mandayam，NarayanRutgers University New Brunswick合作与冲突：频谱共享中的联盟博弈合作通信技术有望促进有效的频谱共享，大量重要的研究已经研究了诸如协作信号处理、协作编码、中继和转发等方法。在研究工作中，人们可能较少考虑到的是，合作可能涉及巨大的成本，最大的直接利益不一定属于承担最大直接成本的用户。例如，协作可能要求终端延迟其自身的传输，并使用其有限的能量预算来为其他终端中继消息。此外，即使在能源或延迟方面没有增加成本，分配利益的规则也可能产生另一种抑制合作的因素。因此，即使在没有任何交易成本的合作，用户合作的总收益只能通过技术，提供足够的激励每个用户，并为每一个transaction.This项目是使用联盟博弈论作为一个框架，以提供显着的洞察合作通信的动态，以及通过这种合作可能实现的激励。结合博弈论与通信和信息理论的模型，研究的合作机制是：（1）接收方合作中的联盟，（2）发射方合作中的联盟，以及（3）联盟形成中的激励和成本。该项目有助于形成联盟的知识和技术，从而改善认知无线电网络中的频谱共享。理论研究活动的一个教育补充是使用ORBIT测试平台来评估简单实用的联盟形成机制。
