On basis of minimizing nodes'additional energy loss,in order to reduce network delay and let the new coming nodes be responded in time,based on Distributed Energy-Aware Node Activation(DEANA)protocol,this paper puts forward Slot Distribution and Adjustment Based on DEANA(SDABD)protocol algorithm and improves expansibility and efficiency of clustered network.It adopts dual-channel technology to solve crosstalk interference,and broadcasts control signal on control channel to inhibit the other nodes sending messages.Simulation results show that on condition of transmitting large amounts of data.it can reduce network delay,response new nodes faster,and enhance network expansibility.
