Abstract: Aiming at the deficiency of low energy adaptive clustering hierarchy (LEACH) protocol, we proposed an improved routing protocol based on clustering mechanism for dynamic grid transmission and data fusion. The improved protocol established a hierarchical clustering routing structure, used the dynamic grid theory to control the data volume transmission, and applied data filtering algorithm for data fusion. Results of simulation experiments indicate that the improved protocol can effectively reduce the energy consumption of network and extend the lifecycle of network.
