WSN multi-hop routing algorithm based on non-uniform clustering

In order to prolong network life, improve network throughput and reduce energy consumption within the network of WSN, a multi-hop routing algorithm for WSN based on non-uniform clustering is proposed in this paper. This protocol effectively alleviates the problem that in the multi-hop data transmission network, the cluster head close to the base station bears too many tasks, and the energy consumption is high, which leads to the premature death of the node. The cluster heads within the direct communication radius in the network will communicate directly with the base station, and the other cluster heads will select the neighbor cluster heads with the least communication cost as relay nodes for multi-hop transmission. Finally, the simulation results show that the protocol can effectively alleviate the premature aging phenomenon in the multi-hop network, and the energy consumption of the nodes in the system is balanced, which meets the design requirements of the wireless sensor network routing protocol.
