| 摘 要： | 为了解决多信道路由同频信道分集的难题,有效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),在选路阶段量化网络编码后传输的性能优势,综合考虑无线信道传输信道差错及干扰的影响,使用能体现网络编码性能优势的判据进行多信道路由选择. 仿真结果表明,该机制在无线多跳网络中能有效地增强节点对数据的处理能力,与传统多信道判据相比,系统吞吐量有10%～20%的增益.

| Abstract: | The problem of intra-channel diversity in multi-channel routing can be relived efficiently using a technology proposed here called network coding.It leads to an increase of the spectral efficiency.In this framework,a coding-aware metric weighted cumulative coding-aware expected transmission time(WCECTT) for multi-channel routing is proposed.It can fairly quantify the network coding gain when considering the wireless transmission conditions and intra-frequency interference.This metric can be used to determin... |
