摘要: 对用于多点传送的DAP-NAD-CJ(周期性跳跃的确定性适应优先网络访问延迟)算法做了改进。新的算法指定在参差不齐的无线信道空位和网络基站之间进行多点传送,以便多点传送的来源信号能尽可能快地进入通道。模拟试验表明,修改后的算法在单一的优先权和多重优先权的网络上都优于DAP-NAD-CJ算法。

Abstract: DAP-NAD-CJ (Deterministic Adaptable Priority Net Access Delay with Cycle Jump) algorithm for multicast application is improved. The new algorithm specifies the multicast betueen uneven wireless channel space and network base station, so that the multicast source signal to enter the channel as soon as possible. The simulation shows the modified algorithm in single and multiple priority network is better than the DAP-NAD-CJ algorithm.
