基于数据块优先级的无线多跳Mesh网络数据分发算法
Wireless multi-hop Mesh network data distribution algorithm based on data block priority
摘要
Abstract
The Mesh-Pull distribution scheme is mostly used to improve the wireless multi-hop Mesh network data distribu-tion algorithm,which leads to the poor transmission performance,and insufficient distribution delay of massive data. The wire-less multi-hop Mesh network data distribution algorithm based on data block priority was designed. On the basis of Mesh-Pull method,the optimal selection mechanism is defined by considering the interference effect of data throughput and time delay. The data block priority is introduced to determine the request sequence of the transmitting data block in network. The bandwidth and signal to noise ratio(SNR)of Mesh network are estimated to find out the optimal neighbor node. The simulation data shows that,in comparison with the Mesh-Pull data distribution algorithm,the improved algorithm has lower network delay and higher network throughput.关键词
