简介：在里面无线多点传送，网络编码最近作为实质的改进吸引了注意到包重发计划。然而，发现最小化重发的最佳的网络代码的问题是难的解决或接近。这份报纸论述二个计划减少重发的数字为可靠高效地多点传送。一个人是用网络基于改进Vandermonde矩阵(VRNC)编码的重发，其它是用网络基于适应改进Vandermonde矩阵(AVRNC)编码的重发。用VRNC计划，发送者都选择包接收装置与改进Vandermonde失去了并且编码他们矩阵；当接收装置收到足够编码的重发包时，所有失去的包能被恢复。与AVRNC计划，发送者能在每重发包，然后改进Vandermonde矩阵发送以后从所有接收装置获得恢复信息能被更新，因此减少编码并且译码的复杂性。我们的建议计划能完成假定重发包的理论更低的界限无损失，并且就重发包损失而言接近理论更低的界限。模拟结果证明建议算法能高效地减少重发的数字，因此改善的传播效率。
