Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047]The present invention comprehensively considers the impact of the remaining energy of the nodes and the average energy on the cluster head election mechanism, and gathers the candidate nodes of the cluster head nodes by judging whether the remaining energy of the nodes is higher than the average energy before each round of cluster head election It is controlled in the range of nodes with higher energy, and a weighting coefficient is introduced at the same time, which improves the chance of nodes with higher energy becoming cluster heads, stabilizes the number of cluster heads in each round, and significantly improves the stability and energy utilization of the network. Make the network obtain better data transmission capacity.

Abstract

The invention provides a clustering routing method of a micropower wireless sensor network based on energy difference. The method comprises following steps of initializing network nodes; determining position distribution of each network node; initializing energy; dividing a network region into multiple clusters, wherein each cluster comprises a cluster head node, and other nodes in the cluster are member nodes; selecting the cluster head node of each cluster in a circular election mode; after a round of cluster head node selection is finished, selecting the closest cluster head nodes by non-cluster head nodes; joining in the clusters, thus being the member nodes of the clusters; and carrying out stable data transmission by each network node through taking the cluster as a unit. According to the clustering routing method of the micropower wireless sensor network based on energy difference provided by the invention, the stable life cycle of the network can be prolonged; and the energy effectiveness problem of the micropower wireless sensor network is solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a micropower wireless sensor network clustering routing method based on energy difference, which can effectively solve the problem of energy availability of the micropower wireless sensor network. Background technique [0002] In order to adapt to the development trend of smart grid, various acquisition systems in this field must be able to actively collect, effectively share and monitor power consumption information in real time. In the future, the development of power grids will not only be limited to the collection of electricity consumption information, but will also move closer to intelligence in terms of information sharing, power procurement and sales. The selection and application of communication schemes are the most difficult points in the intelligent construction of the system, and even the key to success. Choose a safe and stable method to communicate ...
