Abstract: Band-type wireless sensor networks have special topology structure and meet the needs of many important areas. In order to address the issue of the energy consumption unbalance in band-type wireless sensor networks, this paper analyzes the topology structure and energy consumption model of band-type wireless sensor networks in multi-hop communication, on the basis of band-type network clustering, this paper proposes a non-uniform node deployment strategy that quantifies the number of nodes in different clusters in a band-type wireless sensor network and designs the corresponding routing protocol. The simulation results show that the non-uniform node deployment strategy can alleviate the energy hole problem in the band-type network, in addition, the network energy consumption tends to be balanced and the life cycle of the whole network is extended.
