Abstract
Device to Device (D2D) communications appear like an emergency solution for the Public Safety Network (PSN) when the LTE cell range is limited. D2D networks can use the unlicensed frequency bands, as this makes their transmissions cheaper and easier to deploy. Therefore, the development of this technology must deal with the security challenge. On the one hand, it is important to know how to design a secure D2D solution within the small cells, and on the other hand, the new scheme needs to deal with the problem of radio resources limit, since it will be used during emergency situations. This paper develops a new algorithm, named Generalized Secure Network Coding-based Data splitting algorithm (G-SNCDS), to ensure a secure data transmission for Public Safety D2D communications over LTE Heterogeneous Networks (HetNets) and 5G networks, without using additional radio resources. Our approach consists of performing Network Coding (NC) data packets transmissions based on a new Data Splitting (DS) technique, which we developed, based on a constructed butterfly effect that uses a new Butterfly network algorithm that we propose. Our solution enhances the security without affecting the level of Quality of Service (QoS). Thus, it is more suitable when network resources are limited. The simulation results show that our approach provides a secure D2D communication without increasing the overhead in the network.
Highlights
Disaster management is certainly an important issue that attracts public attention
We show the results of the Generalized Secure Network Coding-based Data splitting algorithm (G-solution combined with DS mechanism (SNCDS)) algorithm implementation carried out in Matlab. e aim of our experiments is to illustrate that our scheme enhances the security level in the mesh network without adding significant additional control traffic. ree kinds of attacks are implemented, namely, the confidentiality attack, the integrity attack, and the availability one
D2D technology is an attractive solution to enhance the performance of Public Safety communications over LTE Heterogeneous networks and 5G networks, when the Public Safety access to the shared commercial radio bands over LTE cannot overcome the lack of PS resources during crisis
Summary
Disaster management is certainly an important issue that attracts public attention. During a crisis, any information is vital to save lives. at’s why the Public Safety Networks (PSNs) are deployed. At’s why the Public Safety Networks (PSNs) are deployed. It facilitates the first responders’ communications through exclusive frequencies. Erefore, sometimes, the nodes within the disaster area are unreachable, and sometimes the resources are limited. Both of these situations can affect seriously the efficiency and the reliability of the disaster management process. Us, the Device-to-Device (D2D) [1, 2] communication, deployed in LTE Heterogeneous Networks (HetNets) [3] and 5G networks using the unlicensed frequencies have become more relevant to the Public Safety (PS) data transmission, because of its availability and the lower cost of radio resources that it uses, for its easy deployment within the unreachable areas Both of these situations can affect seriously the efficiency and the reliability of the disaster management process. us, the Device-to-Device (D2D) [1, 2] communication, deployed in LTE Heterogeneous Networks (HetNets) [3] and 5G networks using the unlicensed frequencies have become more relevant to the Public Safety (PS) data transmission, because of its availability and the lower cost of radio resources that it uses, for its easy deployment within the unreachable areas
