Abstract: SECURE LONG RANGE DEVICE TO DEVICE COMMUNICATION METHOD FOR IOT 
DEVICE USING LOW POWER WISE AREA NETWORKS (LPWAN) 
Abstract 
At the end of 2022, nearly, more than 70 billion devices are connected for performing 
secured transaction between device to device while they are connected by Internet of 
Things (loT) platform. It induces required secured data communication established two 
device users for their need includes net-banking, online shopping, and easy money 
transferring app etc. For all above activities a flexible, secured, and long range with low 
power network is required which will be enhanced the characteristic of multi-disciplinary 
applications. It is referred as Low Power Wide Area Networks (LPWAN). It is famous radio 
communication technology consume low power and provide high data rate for long distance 
coverage. It is primary characteristic requirement for secured device to device 
communication and need D2D traffic management, energy efficiency, extended range 
coverage, security framework, and interconnecting. However, in the real time scenario 
LPWAN faces issues like network management, device traffic control strategy energy 
efficient device deployed network security and software integrity. There are several 
architectural options available for interconnecting device namely Sigfox, NBoT, LoRaWAN, 
Narrowband loT (NB-loT), and long-term evolution (LTE)-M among others in terms of loT 
factors. In this research work focus on designing a flexible of structure selection based on 
the requirement of specific application and provides an efficient solution to device secured 
connectivity, extended battery lifetime and coverage. It takes the advantage of structure 
latency and QoS in terms of service and security. It is ensuring that the modified LPWAN 
technologies increase success factors and withstand for various application tested at 
different real time scenario. Especially, today's business market is expanded lot and 
provides huge space for young business mind to earn money as well as improve technical 
skill set in the aspects of loT platform. Such technology helps lot to acquire benefit and 
provide exponential growth of marketing industries by improving customer connection.  
Thereby, it will help the business industry to make the product and increasing selling 
strategy for long period effectively based on the LPWAN technology. It also impacts on 
features like scalability, security, immutability and auditing, data flows, tractability and 
interoperability.
