Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] The wireless sensor network data transmission method based on feedback information and multi-path routing of the present invention has low algorithm complexity, high security and low resource consumption.

[0016] The wireless sensor network data transmission method based on feedback information and multi-path routing mainly includes safe path construction based on feedback information, multi-path routing and multi-path data transmission. In the safety path construction based on feedback information, the "tracking-feedback" mechanism is mainly used to support safe data collection. Based on the assumption that if a data packet in a wireless sensor network reaches the sink node successfully from the source node, then the path from the source node to the sink node is potentially safe for subsequent data transmission. In terms of multi-path routing, the multi-path routi...

Abstract

The invention discloses a feedback information and multi-path routing based wireless sensor network data transmission method which comprises a feedback information based safety routing structure, multi-path routing establishment and multi-path routing transmission application. According to the feedback information and multi-path routing based wireless sensor network data transmission method, in the multi-path routing aspect, the multi-path routing protocol of on-demand routing is mainly adopted, and multiple maximum disjoint routing paths are established, and therefore network congestion is prevented, and available wireless sensor network resources are effectively initialized. Through the feedback information based safety routing structure, feedback paths can be obtained from Sink node for an originating node of data transmission. When the originating node receives enough feedback paths from the Sink node, the paths can be utilized for multi-path data transmission with combination of multi-path routing.

Description

technical field [0001] The invention relates to a data transmission method of a wireless sensor network, in particular to a data transmission method of a wireless sensor network based on feedback information and multipath routing. Background technique [0002] The unattended nature of wireless sensor networks makes the entire network vulnerable to hostile attacks; on the other hand, nodes in wireless sensor networks are also prone to failure due to limited resources. Nodes that are captured by hostiles or malfunctioning nodes in the network are collectively referred to as abnormal nodes. Abnormal nodes will become "black holes" for data transmission in the network. The security of data transmission is the key to ensure the normal operation of wireless sensor networks. Therefore, how to detect and deal with abnormal nodes is an important issue in the field of wireless sensor network security. Security techniques for wireless sensor networks can be divided into two categori...
