Research And Implementation Of Long-distance Multi-hop Network Based On RT-Thread

In recent years,with the rapid development of the power Internet of Things,wireless sensor networks have developed more broadly on this basis.It is an important means for the development of the power Internet of Things.It requires the development of a new wireless sensor network protocol stack.One of the keys to determining whether a wireless sensor network can work efficiently is the reliability and feasibility of the wireless sensor network protocol stack.Most of the protocols are for star networks and mesh networks.The proposed network is not applicable to the linear long-distance multi-hop network in the power Internet of Things.This paper makes related research around the linear topology network,and conducts research on the two aspects of multi-hop transmission and low power consumption protocol.Firstly,in view of the shortcomings of the protocols applicable to star networks and mesh networks,the existing protocol stack is used as the underlying protocol to reconstruct a new protocol stack suitable for linear long-distance wireless sensor multi-hop networks,and a four-layer protocol architecture Protocol stack.The feasibility and reliability of this protocol stack are analyzed through testing,and the improved time synchronization algorithm suitable for linear networks is compared with the traditional time synchronization algorithm.The test results show that the improved time synchronization algorithm is more suitable for multi-hop networks.Secondly,the node deployment strategy is studied,simulated the deployment strategy and the non-deployment strategy algorithm are selected.The test and analysis of the node minimum density non-uniform deployment strategy are more suitable for multi-hop networks,and the life of the network under the node minimum density non-uniform deployment strategy is summarized.The period is approximately times the relationship of uniform deployment,which provides a basis for the study of multi-hop networks suitable for linear long-distance wireless sensors.Thirdly,in order to verify the feasibility of the new protocol stack,this project simulate the power sensing system environment from the perspective of practical applications.It adapts MATLAB simulation and field measurement to analyze and obtain a multi-hop network route,which is suitable for long-distance transmission of this protocol stack depth.Finally,the proposed protocol stack is applied to the wireless sensor nodes designed in this paper through transplantation.Through hardware debugging,the expected effect of the experiment is achieved.Moreover,the results obtained verify that the protocol developed in this paper is reasonable and effective,which extends network transmission to a certain extent.While weighing the network energy consumption,the distance extends the network life cycle to a certain extent.
