Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0043] The invention proposes a data packet error detection method based on a generated field. The invention mainly detects whether an error data packet is caused by a conflict scene, thereby avoiding the hidden terminal problem in the network and improving network transmission performance. The cause of the error packet can be judged by detecting a single error packet, and the error detection ha...

Abstract

The invention discloses a data packet error detection method and a data packet error detection apparatus based on a generation domain. The data packet error detection method comprises the following steps: inserting generation domain blocks in front and rear areas of a data packet before transmission to generate a front generation domain block and a rear generation domain block, wherein the insertion position of the generation domain block located in the front area is symmetrical to the insertion position of the generation domain block located in the rear area; receiving the data packet with the inserted generation domain blocks, and detecting the average error rate of the front generation domain block and the average error rate of the rear generation domain block; and determining a data packet error type according to the average error rates of the front and rear generation domain blocks, and a bit difference ratio of the average error rates of the front and rear generation domain blocks. In the transmitted data, by inserting the generation domain into the to-be-transmitted data, receiving the transmitted data, detecting the average error rates of the front and rear generation domain blocks and the bit difference ratio of the average error rates of the front and rear generation domain blocks, and determining the error type in the data transmission process according to the two factors, the judgment of the error type is achieved.

Description

technical field [0001] The present invention relates to the technical field of detection of data transmission errors in wireless sensor networks, and more specifically, to a generation field-based data packet error detection method and error detection device. Background technique [0002] Wireless sensor networks have applications in various fields such as military applications, environmental detection, health care, and smart cities. However, the performance of the network is easily affected by the transmission environment, resulting in packet transmission failure. The reasons for this phenomenon are mainly divided into two categories: non-collision errors at the physical layer and conflict errors at the media access control layer. Non-collision errors occur in non-collision scenarios, including path loss, multipath fading, shadow fading, and IEEE 802.11 interference. Error packets in these scenarios are sporadic and non-persistent. Conflict errors occur in conflict scenar...
