中文摘要：
为解决Adhoc网络缺乏媒质接入控制（MAC）层的协调机制，低优先级数据流对高优先级的数据流存在很大影响的问题，提出了一种基于模糊逻辑的MAC协议．该协议在MAC层通过模糊逻辑协调各个相关数据流调整其初始退避窗口大小，从而保证高优先级数据流能在较高背景负荷下，维持较高端到端吞吐量和较低端到端接入时延．通过仿真证明，在网络背景负荷超过20％后，该协议能更好地保护高优先级数据流端到端时延和吞吐量．
英文摘要：
In Ad hoc networks, the low priority flows have significant influence on high priority flows because the cooperative mechanism does not exist in medium access control （MAC） layer. To resolve the problem, a new MAC protocol based on fuzzy logic is proposed. It can protect the high priority flows maintain high end-to-end throughput and low delay under heavy background loads, through cooperating relative flows using fuzzy logic mechanism in MAC layer. The new protocol can better protect the end-to-end delay and throughput of high priority data flows when the networks＇ background load is over 20 % in simulation.
