Embodiment Construction

[0052] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0053] Such as figure 1 As shown, the present invention provides a method for optimizing the topology density associated path selection of farmland wireless ad hoc networks, including the following specific steps:

[0054] Step S1: Calculate node energy to vote and determine the cluster head. Among them, the nodes enter the dormant state successively according to the order in which the network collection and uploading are completed.

[0055] Specifically, all nodes start the cluster head election at the same time, select the neighbor node with the highest remaining energy to vote according to the remaining energy of the node, each node weights the votes obtained by topological density, and finally the node with the most votes becomes the cluster head. Peripheral nodes select reachable cluster heads to join the cluster, and the process also includes an ...

Abstract

The invention relates to a farmland wireless self-organizing network topology density correlation path selecting and optimizing method. The method includes the steps that firstly, node energy is calculated, voting is carried out, and cluster heads are determined; secondly, nodes within a preset threshold value are received by the cluster heads and added, and clustering operation is carried out; thirdly, nodes corresponding to which clustering operation is not completed become intra-cluster sub-nodes according to a pre-established method; fourthly, energy advantage nodes are selected from the intra-cluster sub-nodes to serve as fake cluster heads; fifthly, reverse scattering and networking are carried out according to the cluster heads and the fake cluster heads; sixthly, environment information collecting and reporting are carried out on all nodes through a networking route; seventhly, whether a cluster head arrives at an energy approximating target or not is judged; eighthly, if a cluster head arrives at the energy approximating target, the next round is marked to carry out cluster head election, collection of the current round ends, and otherwise collection of the round ends. By means of the method, clustering efficiency is improved, cluster head selection frequency is lowered, and overall network energy efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a method for selecting and optimizing a farmland wireless ad hoc network topology density correlation path selection. Background technique [0002] The routing protocol is the core technology of the wireless ad hoc network network layer. The traditional wireless ad hoc network has proposed many protocols and improvement methods based on improving the quality of service (Quality of Service, QoS) and network fairness. The research focus of these protocols is mainly It is to reduce end-to-end delay, avoid channel congestion, improve network utilization, and reduce average energy consumption. [0003] Through literature search, it is found that the routing algorithms of ad hoc networks can be mainly divided into flat routing protocols and hierarchical routing protocols. Flood routing protocol is the most traditional planar routing protocol. The source node broadcast...
