摘要

嵌入式传感器网络(ESN)的传输效率由于误码率高和信道条件不一致而低于传统网络。在各种应用的部署中，传输效率低至47%。ESN中的传输错误可以通过自动重复请求、错误控制编码或混合ARQ三种基本方法进行恢复。本文提出了基于回声状态网络的能量约束下的错误恢复协议选择的见解。我们将ESN应用分为三大类，这大大简化了选择。此外，我们开发了一个能量模型来整合这三种方案，并根据预期通道条件和回声状态网络分类得出选择的推论。我们将能量驱动的选择应用到两个案例研究中，演示了选择错误恢复协议的简化过程。

Energy Driven Choice of Error Recovery Protocols in Embedded Sensor Network Systems

The transmission efficiency of embedded sensor networks (ESN) is lower than that of conventional networks due to high bit error rates and inconsistent channel conditions. Transmission efficiency as low as 47% has been experienced in deployments for various applications. Transmission errors in ESN can be recovered using three basic methods, automatic repeat request, error control coding or hybrid ARQ. This paper presents insights into the choice of error recovery protocols guided by the energy constraints imposed by ESN. We classify the ESN applications into three major classes, which significantly simplifies the choice. Further, we develop an energy model to incorporate the three schemes and draw inferences on the choice based on expected channel conditions and ESN classification. We apply the energy driven choice to two case studies, demonstrating the simplified process of choosing error recovery protocols.
