摘要: 提出一种改进的GAF算法,将GAF的正四边形网格改变为正六边形方式,加上分层群组控管机制,来达到更好的省电效果.基于MATLAB进行了GAF及改进GAF算法的性能分析,分别进行了高速及低速环境下两个算法的性能分析,结果显示,提出的GAF改进算法在网络生存时间、平均数据传输延迟、数据包发送率等方面均优于GAF算法.Abstract: An improved GAF which changes the perfect square network into regular hexagon as well as hierarchical group control mechanisms achieves a better purpose of saving electricity.The analysis of GAF and improved GAF algorithm on the basis of MATLAB in high-speed environment and low-speed environment shows that the improved GAF precedes GAF in network lifetime,average data transmission delay and packet delivery rate.
