用于多信道路由的完全编码意识的判据

为了解决多信道路由同频信道分集难题，从而有效的提高系统频谱利用率，提出一种新的具有网络编码意识的多信道路由判据WCECTT (Weighted Cumulative Coding-aware ETT)，在选路阶段量化网络编码后传输的性能优势，并综合考虑无线信道传输信道差错及干扰的影响，真正实现了具有完全编码意识的多信道路由。使用C++实现配置了WCECTT的无线多跳系统并进行性能仿真，结果表明该机制在无线多跳网络中，能够有效地增强节点对数据的处理能力，相比于不使用网络编码的系统，具有10%-20%的系统吞吐量增益。

A novel network coding-aware metrics for multi-radio routing

The problem of intra-channel diversity in multi-channel routing can be relived efficiently using new proposed technology called “Network coding”, and hence spectral efficiency can be increased. In this framework, a novel routing metrics WCECTT (Weighted Cumulative Coding-aware ETT) which fairly quantify the network coding gain while considering the wireless transmission conditions and intra-frequency interference is proposed. This metric can be used to determine the optimum path from the coding-available paths and the coding- unavailable ones. We implement the WCECTT routing in wireless mesh system in C++ and conduct extensive evaluation, and the simulation results illustrate that compared with the ones which oblivious of coding gains using ,transmission efficiency can be sharply increased in the whole network and achieves 10%-20% throughput gains.
