同时，鉴于无线链路上传输的不可靠和高误码率，详细介绍了跨层协议设计的相关内容。
Furthermore, the design of cross-layer protocol is described in detail due to the fallibility of wireless links.
仿真结果表明，在移动自组织网络中，该能量有效的跨层协议不但能延长网络的生存时间，减少端到端延迟，而且可以提高网络吞吐率。
The simulation results indicate that the proposed protocol in mobile ad hoc networks can prolong the network lifetime, decrease the end-to-end delay and improve the network throughput ratio.
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。
Therefore the existing protocol stack improved by cross-layer design will be helpful to promote the performances of the next generation wireless system.
