Method and system of determining and optimizing throughput of short distance wireless network

Abstract

The invention relates to a method and a system for confirming and optimizing the throughput rate of short range wireless network. The invention mainly obtains every time parameter of competing visit period according to the information transmission characteristic of the short range wireless network. Every time parameter is used for calculating and optimizing the throughput rate of network. The time parameter is confirmed based on non-persistent carrier wave interception multipoint access CSMA. So the invention uses non-persistent CSMA for analyzing short range wireless network (competing visit period), which simplifies the complex degree of the whole process of confirming network throughput rate and network optimization and analysis. So the throughput rate parameter of short range wireless network of normative network can be obtained with accuracy, which facilitates the optimization treatment to network performance. The performance of short range wireless network is effectively improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for determining and optimizing the throughput rate of a short-distance wireless network. Background technique [0002] At present, short-distance wireless networks include wireless communication networks such as WPAN (Wireless Personal Area Network) and WSN (Wireless Sensor Network). In order to provide communication solutions for short-distance wireless networks such as WPAN and WSN, the IEEE802.15. Access control) layer protocol, the transmission range specified by it is about 10 meters from the typical distance of WPAN. [0003] The main features of WPAN are low speed, low power consumption, low complexity and a large number of wireless nodes. Potential applications include sensors, remote-controlled toys, smart badges, remote controls, and home automation devices. The solution provided by IEEE802.15.4 has low energy consumption and complexity, so ...

[0013] Therefore, if the CSMA / CA mechanism of IEEE802.11 is adopted in short-distance wireless networks such as WPAN or WSN, it obviously does not consider the essential characteristics of CSMA / CA in short-distance wireless networks such as WPAN or WSN. There is a large error, that is, it cannot truly reflect the performance of CSMA / CA in short-distance wireless networks such as WPAN or WSN, which will further lead to the inability to optimize network access based on accurate network throughput, thereby making network access successful At the same time, it will also cause the problem of excessive power consumption of network equipment

Moreover, the calculation process of CCA success probability and throughput rate is too cumbersome
