Problems solved by technology

From this, it can be seen that if the terminal nodes in the network perform direct forwarding, a large amount of transmission time and energy consumption are required. This loss increases exponentially with the number of forwarding times.
And because the actual effective data is short, most of the data is occupied by the header of the message protocol
And in severe cases, it may cause high load occupation of the network channel, making it difficult to send due to preemption

Abstract

The invention belongs to the technical field of wireless networks, and particularly relates to a data fusion method. The data fusion method comprises the steps of A, receiving MAC packages of terminal nodes, B, respectively reading header length information of the MAC packages and length information of local temporary register data queues for data fusion processing, C, extracting MAC layer data in the MAC packages, adding the MAC layer data to the local temporary register data queues, D, creating a new MAC package, assigning the data in a current local temporary register to the MAC layer data of the MAC package for encapsulation, sending the new MAC package, and emptying the data in the local temporary register. According to the method, further provided is a data fusion device. According to the data fusion method and the data fusion device, routing nodes can reduce times of forwarding, quantity of data transmission of a single package is increased, and forwarding loads of network channels are reduced.

Description

technical field [0001] The present application relates to the technical field of wireless networks, in particular to a method and device for data fusion in wireless sensor networks. Background technique [0002] Wireless sensor networks are widely used in low-level data collection due to their low power consumption and low cost. As a distributed system, data information is collected, aggregated and transmitted through underlying sensors and other related equipment, and there are many nodes. There may be a large number of nodes sending data at the same time. It has the characteristics of high concurrency and large data volume. However, due to the small amount of data collected by each sensor, the amount of data per sensor in actual transmission is actually very small. [0003] For the data transmission characteristics of high concurrency, high data volume, and small data blocks in wireless sensor networks, a large number of people around the world are investing time and en...
