1Measurement precision
If the CSMA/CA mechanism of IEEE802.11 is used to determine network throughput in short-range wireless networks, then a throughput calculation method is available, but the throughput parameters are inaccurate due to differences in power consumption, RTS/CTS usage, and slotted/unslotted CSMA/CA mechanisms
Solution Approach 1:
The patent changes the parameters of the CSMA/CA mechanism to match the specific characteristics of short-range wireless networks (IEEE 802.15.4). It adjusts the backoff period calculation, contention slot duration, and clear channel assessment probability to reflect the actual network conditions, including lower transmission rates and different power consumption patterns, thereby achieving accurate throughput parameters without requiring complex analysis processes
Solution Approach 2:
Instead of adapting IEEE 802.11 methods to short-range networks, the patent inverts the approach by developing a throughput calculation method specifically tailored to short-range network characteristics. It inverts the standard CSMA/CA parameter values and relationships to suit the lower data rates and different operational modes of WPAN/WSN environments
2Productivity
If network optimization is performed based on inaccurate throughput parameters from IEEE802.11 CSMA/CA, then network access can be adjusted, but the network performance cannot be effectively optimized and power consumption increases
Solution Approach 1:
The patent implements a feedback mechanism where devices monitor clear channel assessment outcomes and adjust their backoff periods and transmission strategies based on observed network conditions. This feedback loop enables dynamic optimization of network access, improving throughput while reducing power consumption by avoiding unnecessary transmissions during congested periods
Solution Approach 2:
The patent makes the CSMA/CA parameters dynamic rather than static. Devices continuously adjust their contention behavior based on real-time network conditions, including changing backoff window sizes and transmission probabilities. This dynamic adaptation allows the network to optimize throughput and minimize power consumption under varying load conditions

These time parameters are determined based on a non-persistent Carrier Sense Multiple Access CSMA mechanism. Therefore, the present invention employs a non-persistent CSMA mechanism to analyze the CAP of a short range wireless network and thus simplifies complexity in determining the network throughput and the analysis process of network optimization. As such, accurate throughput parameters of the standard network of the short range wireless network may be obtained, the network performance may be optimized and the performance of the short range wireless network is improved.
