Design and Implement Adaptive Tree Topology Mechanism For Wi-Fi Wireless Network

摘要: As the demand for Internet of Things increases, wireless network protocols applied to Large-Scale (LS-IoT) is future development direction. Although 5G technology a recent trend, its signal coverage and cost will be key issues. However, Wi-Fi have many protocol-related modules that are quite mature relatively inexpensive. And it has advantages low latency high transmission efficiency. We implement Adaptive Tree Topology Algorithm in tree system data collection make appropriate design corrections overcome influence environmental factors. In implementation testing, was found multiple problems caused by First, interference environment cause packet loss system. Cause routing mechanism collapse. Second, strength weakened due obstacles. addition, previously designed hop selection may unstable paths increase probability disconnection. Third, affects update routing-related packets, which causes node gateway out sync. order above-mentioned influence, we Resend Queue retransmission effectively solve loss, improve time interval reduce collision frequent retransmissions when high. addition mechanism, as another metric ensure establishment chain with smaller hopping stable signal. The maintenance real gather provide more eliminate errors. Furthermore, our algorithm on CC3220MODA. After offer three objective function this Confirm feasibility paper, setting functions suggestions parameters
