摘要

我们表明，当网络的每个节点都是想要向所有其他节点传输信息的源时，网络编码允许在无线自组织网络中实现显著的节能。能源效率直接影响电池寿命，因此是无线自组织网络的关键设计参数。我们提出了一种可实现的方法，用于在这种设置中执行网络编码。我们详细分析了理论案例，并利用所获得的见解提出了一种实用的、完全分布式的方法，用于现实的无线自组网场景。我们解决了诸如设置转发因子、管理代、传输范围影响和移动性等实际问题。我们使用理论分析和分组级仿真。

A Network Coding Approach to Energy Efficient Broadcasting: From Theory to Practice

We show that network coding allows to realize significant energy savings in a wireless ad-hoc network, when each node of the network is a source that wants to transmit information to all other nodes. Energy efficiency directly affects battery life and thus is a critical design parameter for wireless ad-hoc networks. We propose an implementable method for performing network coding in such a setting. We analyze theoretical cases in detail, and use the insights gained to propose a practical, fully distributed method for realistic wireless adhoc scenarios. We address practical issues such as setting the forwarding factor, managing generations, impact of transmission range and mobility. We use theoretical analysis and packet level simulation.
