In a peer to peer (P2P) network, users should cooperate (share resources) for effective operation. To enforce cooperation, incentive mechanisms are employed, which provide preference in service to more cooperative peers. Most of these incentive mechanisms are designed for the networks where upload and download capacities are independent of each other. In a wireless network, there are scenarios where upload and download capacity are not independent: increasing the upload capacity decreases the download capacity and vice-versa. We have demonstrated that some of the existing incentive mechanisms may not be as effective in such a setting. Therefore, we propose a new incentive mechanism for this setting. Using game theory and simulation, we also ascertain the effectiveness of the new mechanism w.r.t the existing ones in fostering cooperation.

在对等（P2P）网络中，用户应合作（共享资源）以有效运行。为了加强合作，采用了激励机制，该机制向更多合作伙伴提供服务方面的优惠。这些激励机制大多数是为上传和下载容量彼此独立的网络设计的。在无线网络中，有些情况下上传和下载的容量不是独立的：增加上传的容量会降低下载的容量，反之亦然。我们已经证明，某些现有的激励机制在这种情况下可能不那么有效。因此，我们针对这种情况提出了一种新的激励机制。使用博弈论和模拟，我们还可以确定新机制与现有机制在促进合作方面的有效性。
