Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings.

[0055] refer to Figure 1 to Figure 7 , a wireless sensor network Gaussian cluster routing control method, comprising the following steps:

[0056] A1. Randomly deploy sensor nodes in the monitoring area, such as figure 2 shown;

[0057] A2. The base station sends routing commands to each node in the monitoring area;

[0058] A3. After receiving the command, the surviving node determines the distance D from the base station tosink , and mark it as a node, and send the package_node information package to the base station;

[0059] A4. The base station determines the number of surviving nodes N all , Energy E residual , distance D tosink and other information, and calculate the total energy E all . due to N all >0, the base station determines the value of the parameter σ according to the scale S of the monitoring area and the cluster radius R;

[0060] A5. The...

Abstract

The invention relates to a Guassian-declustered routing control method for a wireless sensor network. According to the routing control method, a mean value is determined according to the optimal distance between cluster header nodes; standard difference is determined according to the network size and the cluster quantity; and a probability threshold function is determined according to the residual energy of nodes and the average energy of target nodes in a probability band; in the cluster selection process, the distance between the target nodes and known cluster headers is used as a parameter for generating a probability threshold; and in the stage of cluster generation, the nodes select closest cluster headers as final cluster headers. The Guassian-declustered routing control method for a wireless sensor network, disclosed by the invention, has the advantages of achieving more uniform cluster header distribution, reducing the cluster header energy consumption, realizing the uniform entire energy distribution of a network and slowing the network dead speed.
