IEEE 802.15.3标准为高数据速率无线局域网定义了一个被广泛接受的MAC层协议。然而，在IEEE 802.15.3 MAC中没有规定资源分配方案。本文针对60ghz无线局域网提出了一种增强的IEEE 802.15.3 MAC。这种增强依赖于一种新的资源管理方案。该资源管理方案利用60 GHz技术的先进特性，如定向天线的使用，实现了60 GHz无线局域网中TDMA的空间复用。我们已经在OPNET中实现了我们的协议。基于该仿真平台，我们评估了使用我们的添加到IEEE 802.15.3 MAC的优势。我们表明，我们的增强MAC协议显着提高了基于60ghz的wwan的吞吐量和延迟特性。
The IEEE 802.15.3 standard defines a widely-accepted MAC layer protocol for high data rate WPANs. However, resource allocation schemes are not specified in the IEEE 802.15.3 MAC. In this paper, an enhanced IEEE 802.15.3 MAC is proposed for 60 GHz based WPANs. The enhancement relies on a novel resource management scheme. By exploiting the advanced features of the 60 GHz technology, e.g. the usage of direction antennas, our resource management scheme could realize spatial reuse TDMA in 60 GHz based WPANs. We have implemented our protocol in OPNET. Based on this simulation platform we have evaluated the advantages of using our additions to the IEEE 802.15.3 MAC. We show that our enhanced MAC protocol significantly improves the throughput and delay characteristics in 60 GHz based WPANs.
