Efficient and Reliable Link Control Method Based on Complex Channel Service Model
Towards the development trend of wireless communication network applications,there are the issues of high fault tol-erance probability,large real-time variations,and narrow-bandwidth in wireless links,which results in link reliability difficult.,an efficient and reliable link control method basing on complex channel service model is proposed.Firstly,the characteristic of wireless channel service model is analyzed.Secondly,a tightly coupled and efficient adaptive control mechanism based on wireless channel service model is presented,and an adaptive feedback control process in wireless link is designed.Then,the key parameter calculation methods such as group length and maximum number of retransmissions are provided with the frame structure.Simulation shows that with the transmission success rate of 85％to 99％for the minimum group length at the physical level,the best data group length is 2 to 9 times the minimum group length,and the maximum number of retransmissions reduces from 9 to 4.Simulation verification shows that when the length of the packet is 10 to 100 times the minimum group length,compared with the no link control status,the trans-mission success rate is upgraded from l％～90％to over 99.99％,and the average throughput is increased by more than twice.
