Embodiment 1

[0034] The technical solution of the present invention is to adopt a wireless sensor network code distribution method based on umbrella-shaped multi-path non-interference multi-local transmission, including two phase strategies, which are umbrella multi-path establishment phase strategy and non-interference multi-local transmission Mechanism strategies such as figure 1 , which will be explained separately below.

[0035] 1. Umbrella multipath establishment phase strategy

[0036] 1. Umbrella multi-path establishment phase strategy, including: seed node selection, information interaction establishment path.

[0037] At this stage, the selection of seed nodes is carried out first, based on the principle: select a network edge node located at the opposite corner of the source node in the network as the first-level seed node, and the second-level and third-level seed nodes should be located at two adjacent corners of the source node. Selected from the edge nodes of the network a...

Abstract

The invention provides a wireless sensor network code distribution method based on multiple umbrella-shaped paths. The wireless sensor network code distribution method has the following advantages that 1, umbrella-shaped multi-routing paths are established, the space reuse rate is improved, rapid mirror image distribution at a follow-up stage is facilitated, and the distribution efficiency is improved; 2, a mirror image receiving range is widened in a 'multi-receiving and single-forwarding' pseudo-route transmission mode provided with a retransmission mechanism, and the reliability of the paths is ensured; 3, the local transmission relation which is not affected by hidden terminals is formed based on neighbor exploration and a competition subscription theory, message collision is avoided,and the code distribution time is effectively shortened.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, and more specifically, to a code distribution method for wireless sensor networks based on umbrella multipath. Background technique [0002] In a wireless sensor network, the deployment of nodes has the characteristics of a large number of nodes and widely dispersed spatial locations. Some application scenarios are relatively harsh. When the nodes are deployed and the user proposes new network function requirements, the software code image needs to be updated. The traditional The method of manual wired programming has the disadvantages of high labor costs and difficulty in meeting the needs. In this context, using wireless channels as a medium to distribute and upgrade code mirroring through single-hop and multi-hop methods, that is, a code distribution protocol that uses mirroring to update, can effectively solve the above problems. [0003] Traditional code distributio...
