Research On Wireless Sensor Fusion Networking Based On Narrowband Internet Of Things

Wireless sensor network(Wireless Sensor Networks,referred to as WSN)is a wireless network connected by a set of sensors with wireless transceiver function in the form of multi-hop autonomous.NB-IOT(Narrow Band Internet of Things)exists in 4G/LTE,and it is a very critical application.It has the following advantages: low traffic,strong stability,longer time of wireless communication,use lower cost to achieve higher coverage area.Integrating the new NB-IOT technology into the wireless sensor network and combining the advantages of the two,the wireless sensor network based on the wireless sensor network is established,which has a broad application prospect in the fields of national defense and military,medical treatment,intelligent transportation,commercial application and so on.This study first studies the two technologies of WSN and NB-IOT separately,and then combines them to study the related technologies based on the networking structure and integration of WSN and NB-IOT.Then,the coverage method of node redeployment in traditional wireless sensor networks is described.for a series of problems caused by traditional methods,such as poor node connectivity and low coverage caused by no local search of subgroup nodes,based on this,a node redeployment method based on leapfrog algorithm in wireless sensor networks is proposed,which introduces leapfrog algorithm and combines subgroup local search and global information exchange.It is also proposed to initialize the wireless sensor network node,combine the global information exchange with the subgroup,determine the detectable area of the wireless sensor,and use the calculus method to solve the irregular area to get the optimal network node,so that the wireless sensor network node can be redeployed.To sum up,theoretical analysis and practical simulation show that this research method has better node connectivity,higher coverage and node energy,and has higher application value.It is further proved that the construction of wireless sensor network based on wireless sensor network has certain advantages and feasibility in its technical requirements.
