2. Software and hardware platforms We develop the PSMAC testbed on the Software Defined Radio (SDR) platform consisting of GNU Radio and USRP [12, 13]. SDR is a modern approach to wireless communications [15], which allows dynamic reconfiguration of waveforms by software. GNU Radio [12] is an open-source software development toolkit under the GNU General Public License (GPL). It provides signal processing runtimes and processing blocks to implement SDR on RF hardware and commodity processors. GNU Radio applications are usually written in Python scripts, which allows the quick reconfiguration of the protocols, while the compiled C++ codes are used for the signal processing components of physical layer for minimal processing time.

However, the normalized throughput saturates at about 40% when GR-Limited-1 is used in both Bernoulli and On-Off traffic cases, indicating congestion when the offered load exceeds 40%. On the other hand, the GR-PSMAC throughput keeps increasing even when the offered load is close to 100%. The maximum throughput of GR-PSMAC is about twice as high as that of GR-Limited-1.
When a DATA frame is enqueued at the source node, a time stamp will be stored at the source node. When a DATA frame is successfully received, the destination node will attach a time stamp in the ACK frame that records the time when the DATA frame was received, along with the list of sequence numbers. The MAC layer can directly monitor the outgoing queues and the event of frame receptions, which is free from the extra scheduling latency in the upper layers. , in the ACK frame) and stored time stamps.
