摘要:

为有效收集多reader环境下传感器节点的信息,提出了一种高效率的数据收集协议-MRCIC。MRCIC通过前次信息收集的时槽位置来分配本次tag回复信息的时槽位置,缩短了检测区域范围内tag的时间。针对于reader冲突导致的无法检测到多reader相交区域内tag问题,MRCIC采用没有相交区域的其多个reader同时发送询问信息他reader睡眠的方法来收集相交区域范围内tag信息,提高了信息收集的准确率。理论分析与实验结果表明,MRCIC比AMDCU、ALOHA、BT和PIC延迟更短,准确率更高。

Abstract:

In order to collect the information of sensor nodes in multi-reader environment, the MRCIC information col-lection protocol was proposed. MRCIC information collection protocol uses the previous time slot position to assign the slot position where tags replied, and save the execution time of identifying the interrogated tags efficiently. Because of reader collisions problem, the intersecting regions tags couldn't be detected. Hence, in order to detecting them, MRCIC adopts the method that readers which did not have intersecting regions transmit interrogation information simultaneously and other readers sleep, to collect the intersecting regions tags' information. It improves the accuracy of lection. Theoretical analysis and experimental results show that MRCIC gets shorter delay than AMDCU、ALOHAinformation、BTcol-and PIC, and it can reach the significantly accuracy rate.
