SUBJECT: 500-Word Summary of Article About 5G technology
The following is a 500-word summary of a peer-reviewed article about D2D communication in 5G. Following the increased number of devices, we require a faster, extensive, and reliable network. 5G network can satisfy the demand. D2D communication will be an excellent solution for providing a better network service. D2D communication is used for the “physical proximity” of communication devices. In D2D communication, devices will skip the indirect connection between the device to the Base Station and directly connect with another device. According to the authors, “D2D functionality supports high baud rates and reduces latency between devices, making it particularly important in meeting the standards set for 5G network deployment.” [1, p.987]
The authors list four possibilities to explain the difference between traditional wireless communication and D2D communication in a two-layer 5G cellular network. The main feature of D2D communication makes it different from traditional communication: avoid the Base Station or Access Point if two devices are close enough. The devices must establish a connection with Base Station at first to make a connection with others. The second part is devices also controlled by Base Station, but they directly connect because of D2D communication. The third part of the image means devices require much more relays to transfer source to destination if the connection without inclusion the Base Station. The Fourth image shows two devices still direct connecting without Base Station.
D2D communication has more advantages besides the higher security and reduction of costs. It has better coverage, great data transmission speed, reliable communication, using the same radio frequency to transfer more data than others, higher energy efficiency, heterogenous linkage, and low latency. Also, D2D networks can be used in M2M communication in IoT for responses in real-time and support low latency. Also, D2D communication can contribute to IoT in smart cities as its efficient usage of the radio source and small energy cost. Further, between the vehicle-to-vehicle data transmission of data sharing, D2D communication can be used for the V2V communication.
On the essential functions of D2D application, users may find each other for using a social application and transmission data or services on HD video recording device set high requirements for the base network and the spectrum resources. D2D enables in reducing the transmission pressure of the network.
D2D is necessary to enhance the regular security system prepared for every threat. Currently, D2D security is created by many cryptographic algorithms such as Diffie-Hellman and River Shamir Adleman. The paper’s authors identify the potential security vulnerabilities and classify the attacks, such as Impersonation and IP Spoofing, which may create a severe security threat.
D2D communication is a new wireless technology that can reduce the network’s load and become a new social networking tool. In addition, D2D is one of the critical technologies in 5G network, which enables it to support low latency, fast transmission speed, wide-coverage, and low energy consumption.
