Internal network of smart home is constructed by Ad hoc network based on UWB technology. A viable solution is provided for the construction of network MAC protocol according to the category of network transmission services within smart home. For different business types, through the rational division of channels, different MAC protocol strategies are designed specifically, making protocol more focused and practical. This protocol is simulated and validated on NS2 for different and hybrid MAC protocols strategy. Experimental results show that the new designed MAC protocol improve the shortcomings of traditional low-speed wireless transmission and meet the speed requirements of digital multimedia transmission, and prove its rationality and effectiveness.%采用基于UWB技术的Ad hoc网络构造智能家居的内部网络,根据智能家居内网传输业务类别,为智能家居内网MAC协议的构造提供了一种可行的方案.针对不同的内网传输业务类型,通过合理的信道划分,具体设计了不同的MAC协议策略,使得协议更具有针对性和实用性.在NS2上对不同的MAC协议策略以及混合MAC协议策略进行了仿真与验证,实验结果表明,新设计的MAC协议改善了传统无线传输低速的缺点,满足了各类数码多媒体传输速度的要求,验证了协议的合理性和有效性.
