摘要

针对传感器网络中三重隐终端问题

提出了一种基于自适应占空比的多信道MAC协议—MCR

MCR通过多信道预约机制高效地解决了该问题。在理论分析中

通过最小化节点平均信道切换次数的下界得出了节点的最优占空比。为验证MCR中多信道预约和自适应占空比机制的性能

进行了模拟和真实实验

实验结果表明

与其他MAC协议相比

随着信道数及网络负载的增加

MCR提高了网络吞吐量

降低了传输所消耗的能量。

Abstract

Aiming at triple hidden terminal problems in wireless sensor networks

an adaptive duty cycle based multi-channel MAC protocol was proposed

called MCR.MCR efficiently handled triple hidden terminal problems with multiple channel reservation.By minimizing the lower bound of average times of channel switching in MCR

the optimal duty cycle in theoretical analysis was obtained.To investigate values of multiple channel reservation and dynamic duty cycling in MCR

extensive simulation and real testbed experiments were conducted.The results show that compared with other protocols

when the number of channels is larger or loads are heavy

M-cube improves throughput and energy effi-ciency significantly.
