摘要

MACA-P是一种基于RTS/CTS的MAC协议，可在多跳自组织无线网络中实现同步传输。提供这种低成本的多跳和高性能无线接入网络是普及计算的重要实现因素。MACA-P是对802.11 DCF的一组增强，当两个相邻节点同时是接收器或发射器，但接收器和发射器不是邻居时，MACA-P允许在许多情况下并行传输。与802.11一样，MACA-P在数据传输之前包含一个基于争用的保留阶段。然而，数据传输被一个控制相位间隔延迟，这允许多个发送方和接收方对同步他们的数据传输，从而避免冲突，提高系统吞吐量。

MACA-P: a MAC for concurrent transmissions in multi-hop wireless networks

This paper presents the initial design and performance study of MACA-P, a RTS/CTS based MAC protocol that enables simultaneous transmissions in multihop ad-hoc wireless networks. Providing such low-cost multihop and high performance wireless access networks is an important enabler of pervasive computing. MACA-P is a set of enhancements to the 802.11 DCF that allows parallel transmissions in many situations when two neighboring nodes are either both receivers or both transmitters, but a receiver and a transmitter are not neighbors. Like 802.11, MACA-P contains a contention-based reservation phase prior to data transmission. However, the data transmission is delayed by a control phase interval, which allows multiple sender-receiver pairs to synchronize their data transfers, thereby avoiding collisions and improving system throughput.
