A Cross-Layer Approach to Reducing Packet Delay in Polling-Based Multiuser Systems

We consider a system where users are polled for transmission by a central server, and the link layer of each user employs automatic repeat request (ARQ) to ensure error-free delivery of packets. We present a cross-layer approach for reducing average packet delay (queuing delay plus service time). It is known that forward error correction (FEC) schemes can… CONTINUE READING
