摘要 为充分利用无线自组织网络节点所装备的多天线以提高网络性能,提出一种基于空分复用的无线自组织网络接入层协议MADB-MAC(multiple antennas dual backoff-media access control).通过在传输帧的竞争时隙交换多个据手信息,使网络中节点能够以空分复用的方式并行传输.建立网络性能跨层分析模型,考虑物理层检测错误传播的影响,对此协议进行分析.理论分析和数值计算结果表明MADB-MAC能够在不增加占用带宽的前提下有效提高网络吞吐率. To take full advantages of multiple antennas equipped by nodes in ad hoc networks,based on spatial multiplexing, an MAC protocol named multi-antenna dual backoff（MADB-MAC） is presented.Nodes can exchange hand-shake signals in contention slot of transmission frame to implement simultaneous transmission based on spatial multiplexing.Taking to a detailed consideration of detection error propagation in physical layer,a cross-layer analytical model is presented to analyze this protocol.Results of theoretical analysis and numerical computation show that MADB-MAC can improve network throughput remarkably.
