Embodiment

[0076] A method for WSNs clustering multi-hop routing protocol based on improved particle swarm optimization, comprising the steps:

[0077] (1) Network initialization: Number N sensor nodes sequentially, and randomly and unevenly distribute them in the plane monitoring area and stay fixed to form a WSNs. The energy of all sensor nodes in WSNs is limited, but the initial energy of all nodes is the same, processing The ability and communication ability are equal, the energy of the base station is not limited, and it is located outside the WSNs. During the network initialization process, all surviving nodes send their own energy information, location and serial number information to the base station, and the base station receives and saves the information of each node. The calculation process of each round of cluster head election and clustering, forwarding node election and multi-hop transmission path selection is completed by the base station;

[0078] (2) Cluster head electio...

Description

technical field [0001] The invention relates to wireless sensor network routing protocol technology, in particular to a WSNs clustering multi-hop routing protocol method based on improved particle swarm algorithm. Background technique [0002] Wireless Sensor Networks (WSNs for short) realize the three functions of data collection, processing and transmission, which together with communication technology and computer technology constitute the three pillars of information technology. WSNs have broad application prospects in environmental monitoring, military, homeland security, traffic control, medical health, community security, forest fire prevention, and target positioning. [0003] In WSNs, the energy of sensor nodes is provided by their own micro-batteries, and their use time is limited by the energy of the nodes, and the power of the nodes is limited, and the communication radius and sensing ability are limited. The energy consumption of sensor nodes mainly includes co...
