Heterogenous cluster routing method of wireless sensor network based on energy collection

Abstract

The invention discloses a heterogenous cluster routing method of a wireless sensor network based on energy collection. The method comprises the steps that a round concept is adopted; when each round begins, a sensor node in the network elects cluster head nodes in the optimal quantity according to types and thresholds T(s) of the nodes, and determines cluster interior nodes; after network clustering, the cluster head nodes collect and fuse data information acquired by a cluster interior member, and select an optimal routing path according to a routing selection criterion; the path sends fused data to a Sink node; the Sink node analyzes and processes the collected data, and broadcasts to inform all nodes in the network with operating parameters of a network in a next round; the current round is accomplished; and the next round begins. The method is fully matched with the characteristic of the wireless sensor network based on the energy collection, is suitable for the wireless sensor network based on the energy collection, can effectively increase data throughout of the network, and reduces energy consumption of the network.

Description

technical field [0001] The invention relates to a wireless sensor network heterogeneous clustering routing method based on energy collection. Background technique [0002] Wireless sensor network is a new type of sensor network, which is composed of a large number of miniature sensor nodes with perception, computing and communication capabilities. Due to the characteristics of wide coverage area and self-organization, wireless sensor networks have important scientific research value and broad application prospects. An important factor limiting the application of wireless sensor networks is the energy consumption of the network. Traditional wireless sensor networks are powered by batteries, with a short working cycle and cannot be reused. Although with the development of technology, in order to extend the working cycle of the network, based on energy Collected wireless sensor networks have begun to appear and become a reality, but the energy collected by energy harvesting te...

An important factor that limits the application of wireless sensor networks is the energy consumption of the network. Traditional wireless sensor networks are powered by batteries, with a short working cycle and cannot be reused. Although with the development of technology, in order to extend the working cycle of the network, based on energy Collected wireless sensor networks have begun to appear and become a reality, but the energy collected by energy harvesting technology is very limited, only at the milliwatt level. If routing technology is not used, it is still beyond the means. It is particularly important to study the routing protocols of wireless sensor networks, especially the routing protocols of wireless sensor networks based on energy harvesting.
