Embodiment Construction

[0020] A roadway environment-based wireless sensor network clustering routing method, comprising the following steps:

[0021] set cluster head threshold , select the node with the generated random number X is the number of nodes that have been selected as cluster heads in the cycle, is the proportion of the cluster head node among all nodes, E c is the remaining energy of nodes in the network, E strat is the initial energy of nodes in the network, and δ is the root mean square value of roadway wall roughness;

[0022] Set the cluster radius of the cluster head , the cluster head broadcasts clustering information within the clustering radius, waiting for cluster members to join, where θ is the inclination angle of the roadway wall, θ∈(0°,90°), d max is the maximum distance from a node to a base station in the network, d min is the minimum distance from a node to a base station in the network, d i Indicates the distance from the cluster head to the base station, R c i...

Abstract

The invention relates to the field of wireless communication, in particular to a wireless sensor route protocol, and particularly to a wireless sensor network clustering route method based on roadway environment. The method includes selecting cluster heads through a cluster head threshold value; calculating cluster radius, and broadcasting cluster information according to the cluster radius by the cluster heads to wait for cluster members to join in; broadcasting individual information by the cluster members; forming two chainlets in the cluster according to greedy algorithm to transmit information to the cluster heads; and forming multiple hop transmission between the cluster heads to transmit data to a base station. With the improved cluster head selecting method, and energy factors and roadway influencing factors are added, the cluster head threshold value is changed, network energy consumption is equalized and stability is improved. The cluster radius of the cluster close to the base station is reduced, roadway inclined angle factors are added, and dead nodal points around the base station are reduced. Data between the cluster heads are transmitted by the aid of a multiple hop method, so that energy consumption is equalized and roadway environment can be extremely fitted.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a routing protocol of a wireless sensor, in particular to a roadway environment-based wireless sensor network clustering routing method. Background technique [0002] Wireless sensor networks (Wireless Sensor Networks, WSN) can carry out wireless communication without a fixed network structure. It has the characteristics of free networking and strong anti-damage performance. Therefore, it is more suitable for wireless communication in mine roadways. Routing protocols are the core content of wireless sensor networks. Information can be transmitted through routing protocols. Routing protocols play a vital role in the energy consumption and stability of the entire network. Currently, classic hierarchical routing protocols include: LEACH protocol, PEGASIS protocol, TEEN protocol, etc. Downhole channel attenuation also has a great impact on the stable transmission of information....
