Problems solved by technology

This improvement allows nodes that have not been elected as cluster heads for a long time to have the opportunity to become cluster heads, but doing so can easily cause instability in the proportion of cluster heads and affect energy balance

Abstract

The present invention provides a wireless sensor network clustering routing protocol based on natural energy. Prior to each clustering process, the prediction of energy supply which will arrives is performed; some of nodes with maximum residual energy and the most energy supply are selected as cluster heads to undertake more forwarding data tasks than other nodes; the proportion of the cluster heads in the total number of the nodes in a control network; and after the selection of the cluster heads is completed, other common nodes which are not cluster heads are joint for clustering, and the common nodes compare energy consumption cost of each cluster head forwarding data to a base station and then select the cluster head with minimum energy consumption for joint. The wireless sensor network clustering routing protocol based on the natural energy only need low storage cost to effectively establish route so as to improve the network survival time and satisfy communication demand between the wireless sensor nodes. The wireless sensor network clustering routing protocol based on the natural energy is low in cost, high in cost, high in energy efficiency, balanced in energy consumption, high in average energy level of network nodes, and wide in application range.

Description

technical field [0001] The invention relates to a wireless sensor network clustering routing protocol, in particular to a wireless sensor network clustering routing protocol based on natural energy. Background technique [0002] Wireless Sensor Network (WSN) consists of a large number of wireless sensor nodes deployed in the detection area. Nodes cooperatively perceive, collect and process object information in the network area. Energy saving and energy consumption balance have always been important topics in wireless sensor network research. The development of natural energy harvesting technology has allowed the installation of economical and practical energy harvesting devices on nodes, making it possible to extend the life of individual nodes and even the overall network indefinitely. [0003] Due to the resource constraints of nodes, route finding and keeping in WSN is a challenging problem. There are many studies proposing different routing protocols for VANETs. The...
