Multi-Geocast is source node transmits message to all the nodes of multiple regions in wireless sensor networks.The existing Multi-Geocast algorithms in WSN can not do the balance of energy consumption and latency.Though Single Fermat-chain algorithms can reduce energy consumption,but the average transmission delay is great.A Low-cost and Low-latency multi-Fermat chain multi-Geocast Algorithm(LLA)was proposed,which greatly reduced transmission delay while maintaining low energy consumption.In this paper,first,mesh and cluster head selection algorithm was proposed,and then Fermat chain combining triangle and quadrilateral Fermat Point was establishd to improve the success establishment rate of Fermat chain.Finally,we simulated the LLA algorithm and existing algorithm.The results show that LLA is better than existing algorithms in energy consumption and average latency.
