摘要
无线自组网的介质访问控制(MAC)协议是与物理层密切相关的,大多数MAC协议都要求物理层具备载波感知能力。但在一些以小型手持设备为终端的自组网应用系统中物理层无法提供载波感知。为此,在MACA和DCA-PC的基础上,提出了一种不需要载波感知的支持功率控制的自组网多信道MAC协议,通过调整发射功率实现节能,并在一定程度上支持实时传输。
The media access control (MAC) protocol of mobile Ad Hoc networks (MANETs) is closely-related with its physics layer, most MAC protocols request the capability of carrier sense in physical layer. But the physics layer of some small hand-hold equipments can not provide carrier sense. Based on MACA and DCA-PC, a multi-channel MAC protocol with radio power control for MANETs is put forward, which can economize energy by adjusting radio power, and real-time traffic delivery is supported.
