摘　　要：文中分析了在AdHoc网络中采用定向天线时的层间优化和仿真问题。利用ns-2仿真环境对全向天线、切换波束天线和导引波束天线与DSR路由协议和AODV路由协议的不同组合进行了联合仿真,结果表明采用定向天线后的增益和能耗性能都有所改善。该结果为AdHoc网络在不同测量应用环境下选择最佳的天线与协议组合提供了依据。The cross-layer optimization and simulation problem of Ad Hoc network with directional antenna is analyzed in this paper. The simulations of different matched among directional, switched and steered beam antenna combined with the DSR and AODV routing protocols are produced in ns2, which shows that the gain and energy consumption performances are improved with directional antenna. The results can be used as the reference of selecting optimal combination of antenna and protocol for Ad Hoc network under different measurement field.
