摘要 Adhoc网是一种没有有线基础设施支持的移动网络,网络中的节点均由移动传感器主机构成,可以被广泛应用于不便预先敷设网络设施的场合。分析了Adhoc网络物理层与媒体接入控制层的联合优化问题,并在不同的环境下,对不同类型的天线与媒体接入控制协议进行了联合仿真,结果表明采用定向天线后的增益和能耗性能都有所改善。 Ad hoc network is a kind of mobile network without cable infrastructure. The nodes of the network consist of mobile sensors or hosts. It has been widely used in the fields of military communication and data collection from disaster areas. The paper analyzed the combined optimization of the physical layer and medium access control layer of Ad hoc network. The simulation results from the different combinations of antenna and MAC protocols are given under different environments. It shows from the results that the performances of gain and energy consumption are improved with the directional antenna.
