How can D2D and IoT be integrated?

Integration of Device to Device communication in IoT

• Both D2D and IoT are themselves the best technologies that have potentially made positive impacts and changes in different fields.
• When these two technologies are combined, they provide massive developments that become essential for proper real-time implementation needs.
• For instance, let us consider vehicle-to-vehicle communication, which is made possible using device to device communication in IoT. For many instances, like the one in which vehicles try to change lanes or their speeds, a warning signal is sent to the vehicles nearby. As a result, possible accidents can be avoided.

In these methods, D2D communication is impacting internet of things applications in better ways. One of the huge constraints expected in the massive usage of wireless technology in smart system applications is the proper sharing of the licensed spectrum, which is limited. As a result, the performance of next-generation internet of things (IoT) devices can be limited and in-depth research over new communication methodologies can only solve such problems. What are the real-time implementation possibilities of D2D and IoT integrated systems?

• 3GPP – LTE mobile communication system using Qualcomm developed Flashlinq

How D2D is connected in IoT?

D2D technology forms the basis of communication established among devices in the internet of things and smart systems. For typical monitoring and controlling of various network components, they are connected among each other and to the internet using wired and wireless standards like wi-fi, Near Field Communication, 3G, 4G, and 5G networks.

• In device to a device communication network, individual health or related specific data are transmitted from the sensors to the end-users (smartphones), and it is then sent to the base station through the direct link
• In intelligent D2D communication, the following processes take place for the signal to reach from network devices to the tower
  • D2D relay search
  • Broadcasting pilot signals
  • Signal analysis by cellular devices
  • Cellular device response is analyzed using NB – IoT UE
  • Relay selection is formulated as a MAB problem using NB – IoT UE
  • MAB problem is solved by UCB and is then uploaded to BS/eNB

As a result, the Device to Device communication in IoT approach does away with the centralized control making it more efficient in traffic offloading and energy consumption. D2D communication in IoT has managed to drag the attention of students and researchers from top universities. We have helped out many researchers in overcoming the limitations of hardware and resource-related constraints. Consider the following methods used to connect IoT devices for D2D communication.

When you search for communication standards systematically by considering the above points, you will end up finding standards that meet one of the demands while others, like efficiency in consuming power, are foregone. So it becomes important for researchers to spend quality time choosing the best communication for their internet of things devices that can exhibit better performance and energy utilization. It is also crucial to stick to cost-effective approaches to bring out your project to meet the commercial demands. The following is a clear cut analysis of different and prominent communication protocols with their effect on power consumption

• ZigBee (WPAN) consumes medium power and has a standard range of 10 to 100 metres and maximum data rate of 250 kbps
