Broadcasting Delay-Constrained Traffic Over Unreliable Wireless Links With Network Coding
There is increasing demand for using wireless networks for applications that generate packets with strict per-packet delay constraints. In addition to delay constraints, such applications also have various traffic patterns and require guarantees on throughputs of packets that are delivered within their delay constraints. Furthermore, a mechanism for serving delay-constrained traffic needs to specifically consider the unreliable nature of wireless links, which may differ from link to link. Also, as it is usually infeasible to gather feedback information from all clients after each transmission, broadcasting delay-constrained traffic requires addressing the challenge of the lack of feedback information.
