ns2中跨层对网路性能优化较复杂，这个代码提供了一个沙盒，可以支持再多个层次间进行跨层设计。,ns2 in cross-layer performance optimization of the network more complex, the code provides a sandbox, you can support the re-between the various levels cross-layer design.

Ad hoc网络中基于dsr路由协议改进的路由算法FETdsr,实现了在路由层跨层感知MAC层拥塞状况，从而选择拥塞较轻的路径。-Routing protocol for ad hoc networks based on dsr in NS2 simulation. Achieved in the routing layer cross-layer aware MAC layer congestion status, and thus choose less congested path

ns2定时器包的取消,跨层访问,NS2添加协议-NS2 cross layer,cancel packet,timer user
