摘要
为了进一步提高自组网设备的灵敏度和隐蔽性,针对一种低速超短波自组网MAC层协议进行了研究。该协议根据拓扑结构的改变,采用"动态预约和随机竞争"的分配策略,提高了传输效率。应用OPNET对该协议进行了仿真,仿真结果表明,所提出的低速自组网波形协议可以容纳较大的网络规模,具有较小的开销、较短的组网时间以及传输时延。
In order to improve the sensitivity and concealment of MANET,some research on VHF MANET is conducted,and a low speed transmission MAC protocol is proposed.This protocol adopts the scheduling strategy of“dynamic reservation and random competition”to adapt to the change of topology,which achieves a high transmission efficiency.Using OPNET,the proposed protocol is simulated,and the result shows that a larger network size,a lower overhead,a shorter net-forming time and a shorter transmission delay can be achieved by this protocol.
