摘　　要：针对传感器网络周期性数据收集的数据流特点,提出了基于自协商时隙分配机制的自协商分时MAC协议。该时隙分配机制无需集中式处理,具有自适应、分布式、本地化等特点。仿真结果表明,本协议的有效数据收集率及最大数据延时与增添ACK重传机制后的TAG协议相当,而能耗却仅为后者的1/30。On the analysis of data flow characteristics in periodical data gathering applications in wireless sensor networks, an auto-negotiation time division MAC protocol based on auto-negotiation slot allocation scheme was proposed. The slot allocation is carded out in the adaptive, distributed and localized manner. The simulation shows that power consumption in our protocol has been decreased to the one thirty of that in TAG protocol with extended ACK re-transmission scheme, while delivery ratio and maximum data latency suffer no deterioration.
