System throughput improvement by optimizing timeout for wireless network coding and frame aggregation on CSMA/CA bidirectional two-hop relaying prototype.

This paper reports an outdoor experiment to optimize the timeout of wireless network coding (WNC) and frame aggregation (FA), which are implemented to carrier sense multiple access with collision avoidance (CSMA/CA)-based wireless two-hop relay prototype. The system throughput is improved. In the prototype, FA is implemented at the terminal nodes. Timeout function for WNC is available at the relay node and that for FA is available at the terminal nodes. Our outdoor experiment shows that optimizing the timeout values of WNC and FA can improve system throughput by 2.04-fold compared to the conventional relay without WNC or FA. © 2016 Institute of Electrical Engineers of Japan.
