Abstract

The invention discloses a cluster routing method based on hexagonal centroid-based cluster head election and dynamic time slot allocation in the technical field of wireless sensor networks, comprising the following steps: S1: establish a network model; S2: establish an energy consumption model; S3: cluster Head candidate node set; S4: Set the node sequence value; S5: Elect cluster head; S6: Based on variable-length time slot allocation, reduce node energy consumption from the perspectives of cluster head election and time slot allocation. According to the hexagonal grid, the nodes that are close to the hexagonal centroid are preferentially selected as cluster heads. The cluster head then allocates time slots according to the state of the node in the previous round of time frames to improve the utilization of time slots. Simulation data show that the proposed HSDR routing balances the energy consumption and extends the network lifetime.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a cluster routing method based on hexagonal centroid cluster head election and dynamic time slot allocation. Background technique [0002] Wireless Sensor Networks (WSNs) have been widely used in environmental detection, rehabilitation medicine and other applications. Nodes in WSNs have the ability to sense data and transmit data. The sensing node senses the data first, and then transmits the data to the base station. Since nodes within WSNs are tiny devices, they are generally powered only by batteries. Even if the node power is exhausted, it is inconvenient to replace the battery or charge it. Therefore, reducing node energy consumption and improving energy utilization has become a research hotspot of WSNs. [0003] Transferring data consumes most of a node's energy. Therefore, transmitting data efficiently is an effective way to reduce the energy consumpt...
