Therefore the existing protocol stack improved by cross-layer design will be helpful to promote the performances of the next generation wireless system.
通过对现有协议栈进行改进，加入跨层设计方案则有助于改善下一代无线系统性能。
Cross layer design technique which jointly optimize several layers of protocol stack could improve network performance significantly.
联合优化协议栈中各层的跨层设计技术能够显著提高网络的性能。
Secondly, it keeps the low coupling and high cohesion virtue of layers in protocol stack after adding cross-layer design, so as to keep the OSI layering architecture.
其次，它使加入跨层设计后的网络协议栈每个层仍具有高内聚、低耦合的特征，从而保持了网络协议栈良好的软件架构。
