In one implementation mode, if the distance between each sensor node in the cluster and the cluster head does not exceed the set communication distance threshold dσDirectly communicating with the cluster head; if the distance between the cluster head and the cluster head exceeds the set communication distance threshold value dσThe sensor node selects a neighbor node closer to the cluster head relative to the sensor node for communication, and specifically comprises the following steps:
(1) the sensor node selects the neighbor nodes meeting the following path conditions as the candidate next hop nodes in the neighbor nodes closer to the cluster head relative to the sensor node, and the neighbor nodes are classified into the candidate next hop node set:
in the formula, OiCorresponding cluster head, d (j, O), representing sensor node ii) Represents the jth neighbor node to O in the neighbor nodes of the sensor node i closer to the cluster head relative to the neighbor nodesiD (k, O)i) Represents the k-th neighbor node to O in the neighbor nodes of the sensor node i closer to the cluster head relative to the sensor node iiDistance of (m)iThe number of neighbor nodes of the sensor node i which are closer to the cluster head relative to the sensor node i;
(2) and the sensor node selects the neighbor node with the maximum current residual energy from the candidate next hop node set for communication.
Wherein, other sensor nodes in the communication range of the sensor node i are called as neighbor nodes of the sensor node i.
In the communication routing mechanism, whether the sensor node is in direct communication with the cluster head or not is determined through the distance, so that the sensing information collected by the sensor node can be reliably and stably sent to the cluster head. The path conditions are innovatively set, so that when the sensor node with the distance to the cluster head exceeding the set communication distance threshold selects the next hop, the sensor node can avoid selecting the next hop far away from the cluster head, the transmission delay of the sensing information can be effectively reduced, and the occurrence rate of the phenomenon of sensing information packet loss caused by data stream interference during multi-hop transmission is reduced.
In one implementation, the distance between the cluster head and the sink node does not exceed the preset lower distance limit dWhen the cluster head is in communication with the sink node, the cluster head directly communicates with the sink node; the distance between the cluster head and the sink node exceeds a preset lower distance limit dThe cluster head sends the sensing information to the sink node in a multi-hop routing mode, wherein the cluster head selects the neighbor cluster head with the largest weight value as the next hop from the neighbor cluster heads closer to the sink node;

in the formula, QabThe cluster head weight is the weight of a neighbor cluster head which is closer to a sink node from the b th cluster head of the cluster head a, d (b, sink) is the distance from the neighbor cluster head which is closer to the sink node from the b th cluster head to the sink node, d (a, sink) is the distance from the cluster head a to the sink node, sink represents the sink node, d (a, b) is the distance from the cluster head a to the neighbor cluster head which is closer to the sink node from the b th cluster head; lambda [ alpha ]1、λ2Is the set weight coefficient.
In the routing mechanism, when the distance between the cluster head and the sink node exceeds a preset distance lower limit, the cluster head selects a neighbor cluster head with the largest weight as a next hop, so that the reliability of sensing information transmission is improved, the total length of a sensing information transmission path can be shortened as much as possible, and the cost of sensing information transmission is saved.
