Abstract

The invention provides a clustering routing method based on a channel access heterogeneous wireless sensor network. Definition of the channel access heterogeneous wireless sensor network is given, nodes in a cluster use a CRT-UI protocol sequence communication manner, and different from a time division multiplexing communication method, the CRT-UI protocol sequence communication manner can be used to ensure all node data are sent successfully in fixed time delay on the premises that node time is not synchronized strictly. Under the condition that the nodes in the cluster use the CRT-UI protocol sequence communication manner, the number of optimal cluster heads and the optimal probability that a node serves as the cluster head are calculated according energy consumption in each round of the network. According to the invention, the energy consumption in each round of the network is minimal, the stable period of the network is prolonged, and the network throughput is improved.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a clustering routing method for accessing heterogeneous wireless sensor networks based on channels. Background technique [0002] With the increasing rise of the Internet of Things, wireless sensor networks are widely used in military, environmental monitoring, smart home, urban transportation, space exploration and warehouse management and other fields. As a research hotspot in today's information field, wireless sensor networks involve many disciplines, and there are many key technologies to be discovered and researched. Among them, network topology control is of special significance. A good network topology structure automatically formed through topology control can greatly improve routing protocols. and the efficiency of the MAC protocol. [0003] The LEACH algorithm is a classic hierarchical clustering routing algorithm in the homogeneous wireless sensor ne...
