Abstract

In wireless ad-hoc networks using XOR network coding, intermediate nodes are required to XOR packets whenever possible. Although there are lots of existing incentive compatible schemes aiming to provide incentives for intermediate nodes to forward packets, they are not suitable for XOR network coding. In this paper, we first present a basic payment scheme to provide incentives to intermediate nodes to follow XOR network coding protocol. We prove that, under our scheme each intermediate node has incentives to follow the XOR protocol. Then we consider the overpayment in the basic scheme, and propose an enhanced payment scheme using SVM model to reduce the payment to a reasonable level. The results show that under the enhanced scheme, the payments can be reduced by up to 70%, and these payment are close to the real forwarding costs.
一种基于异或网络编码的无线自组网分组转发和减少支付的激励方案
在使用异或网络编码的无线自组织网络中,要求中间节点尽可能地对数据包进行异或。虽然已有许多激励兼容方案旨在为中间节点转发数据包提供激励,但它们都不适合异或网络编码。在本文中,我们首先提出了一个基本的支付方案,以激励中间节点遵循异或网络编码协议。我们证明,在我们的方案下,每个中间节点都有动机遵循异或协议。然后考虑了基本方案中的超额支付问题,提出了一种基于支持向量机模型的增强支付方案,使支付降低到合理的水平。结果表明,在改进方案下,支付费用最多可减少70%,并且这些支付费用接近真实的转发成本。
