Abstract

The invention discloses a wireless network routing path planning method driven by node dynamic coverage. The method comprises the following steps: driving wireless execution nodes to move to a networkdesignated location through a driving device; taking the output of a location sensor as the feedback, and performing location updating on the wireless execution node in drifting under the driving ofthe driving device; forming a whole target region execution node non-uniform coverage model; dividing the wireless execution nodes into different clusters; judging whether the intra-cluster node relative geometrical distance and the residual energy are optimal, wherein the intra-cluster node execution node transmits data to the cluster head node, and the cluster head node transmits the data to a relay node along a neighbor cluster head node. The wireless network coverage rate and the network energy consumption are improved, and the data transmission performance of the sensing parameter in a monitoring region is improved.

Description

technical field [0001] The invention relates to a wireless network routing path planning method driven by node dynamic coverage, and belongs to the technical field of wireless network node coverage, routing path and network construction and maintenance. Background technique [0002] With the development of electronic technology, communication technology and networking technology, the wireless nodes have the characteristics of low cost, power consumption and small size, as well as the functions of perception and communication. In order to form a self-organizing network system in a wireless way, cooperation can be completed The tasks of parameter perception, data processing, and network communication in the monitoring area have made wireless sensor networks widely used in environmental monitoring, health monitoring, industrial monitoring, and security. Different from some monitoring networks that are connected in the form of wired, there are disadvantages such as difficult ins...
