摘要： 为了在尽量减少节点额外能耗的基础上实现对新加入节点的及时响应和减小网络延时，基于分布式能量感知节点活动协议提出SDABD算法，对分簇网络的可扩展性及实时性进行改进。采用双信道技术解决串音干扰问题，通过在控制信道上广播控制信号抑制其他节点发送信息。仿真结果证明，在大量数据传输时该算法可明显降低网络延时，更快地响应新加入节点，增强网络的扩展性。

Abstract: 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.

Key words: Wireless Sensor Network(WSN), Slot Distribution and Adjustment Based on DEANA(SDABD) algorithm, clustered network, network real-time performance, network expansibility
