带边信息的变带宽直接组播时延最小化

Delay Minimization in Varying-Bandwidth Direct Multicast with Side Information

Son Hoang Dau, Zheng Dong, Chau Yuen, Terence H. Chan

摘要:

我们研究的延迟最小化的直接组播通信方案中,一个基站希望发送一组原始数据包的客户端。每个客户端在其缓存中已经有原始数据包的子集,并请求所有剩余的数据包。基站通过向客户端广播信息来直接与客户端通信。假设工作站和不同客户端之间的带宽不同。我们提出了一种方法,以尽量减少基站满足所有客户端的请求所需的总延迟。

英文摘要:

We study the delay minimization in a direct multicast communication scheme where a base station wishes to transmit a set of original packets to a group of clients. Each of the clients already has in its cache a subset of the original packets, and requests for all the remaining packets. The base station communicates directly with the clients by broadcasting information to them. Assume that bandwidths vary between the station and different clients. We propose a method to minimize the total delay required for the base station to satisfy requests from all clients.
