摘要:

介质访问控制协议在很大程度上决定了无线自组网的性能。本文在介绍CTMAC协议的基础上对该协议的并发规则进行了证明,并从理论上讨论了CTMAC协议的开销。通过模拟并 与IEEE802.11和MACA-P比较表明,CTMAC协议可以有效地提高网络吞吐量。

关键词: 无线自组网 CTMAC 吞吐量

Abstract:

In wireless ad hoe networks, the performance of the media access control (MAC) protocol has significant impact on the overall network performance. B  ased on the introduction of the proposed CTMAC protocol, we prove the concurrent control rules and compute the cost of CTAMC by a theoretical analysis. Compared with IEEE 802. 11 and MACA-P, our simulation results show that CTMAC can improve the throughput of network effectively.
