5G Network

The fifth-generation (5G) network assimilates terahertz bandwidth and machine type communication (MTC) for swift and reliable data transfer and information exchange. It incorporates sophisticated cloud, Internet of Things (IoT), and other software-defined architectures for providing scalable service support. However, due to the heterogeneous integration of devices and architectures, secure infrastructures needto become mandatory. In this article, a Blockchain-based Versatile Security Framework (BVSF) is introduced to provide robust and adaptable authentication and access control in the 5G environment. The proposed framework allocates blocks for user equipment (UE) authentication and resource access control in a parallel manner. The verification of security level between resources, infrastructures, and UEs aids in extending or attenuating blockchain services. Based on the different security level assessments, the UE requests are precisely mapped or reallocated to the resources, improving the response rate and the framework adaptability.

Research on the provision of heterogeneous services in the field of intelligent transport is of great interest in the rapidly changing infrastructure of road transport. In particular, the availability of such services has increased through the use of wireless technologies and communication tools. The current development of Information Communication Technologies (ICT) and the integration of intelligent transport platforms and service systems make it possible to significantly improve road safety and reduce the likelihood of road accidents. However, the delivery of mobile-smart services requires the development of a rather sophisticated infrastructure to support multicast services. The purpose of this scientific article is to analyze the data transmission capabilities for heterogeneous services while ensuring road safety. The paper deals with the tasks of evaluating the possibilities of integrating such mobile services into the infrastructure of motor vehicles. Measuring bandwidth by enabling multicast services on the base of Ad-hoc wireless networks becomes an important task. The demonstrated results illustrate the capabilities of wireless networks by simulating these services in a transport service generating environment. The paper demonstrates that high-quality heterogeneous services require new wireless network interaction protocols, such as a session initiation protocol (SIP), GPRS functionality, routing protocols, and channel access to provide a large number of supportive service components.

Emergency Scenarios

In Mobile Ad-hoc Networks (MANETs) the major issue between nodes for data transfer is link quality. The majority of the MANET routing protocols try to maintain the link quality between nodes but still need improvement. This paper focuses on link quality between nodes in an ad hoc network in emergency scenarios through the design of the Energy Priority and Link Aware Ad-hoc On Demand Distance Vector (EPLAODV) routing protocol. EPLAODV improves the link quality between nodes through SNR. For performance analysis, the NS2.35 network simulator was used. Simulation time and traffic load were the major simulation parameters. From the simulation results, it is observed that EPLAODV performs better than AODV.

The increased adoption of social media has presented security and law enforcement authorities with significant new challenges. For example, the Swedish Security Service (SÄPO) asserts that a large proportion of radicalization takes place in open fora online. Still, approaches to contain social media-driven challenges to security, particularly in democratic societies, remain little explored. Nonetheless, this type of knowledge may become relevant in European countries in the near future: Amongst other factors, the challenging economic situation has resulted in increased public discontent leading to emergence or manifestation of groups that seek to challenge the existing policies by almost any means. Use of social media multiplies the number of vectors that need law enforcement attention. First, a high level of social media adaption allows groups to reach and attract a wider audience. Unlike previously, many groups today consist of a large but very loosely connected network. This lack of cohesion can present a challenge for authorities, to identify emerging key actors and assess threat levels. Second, a high level of mobile web penetration has allowed groups to ad-hoc organize, amend plans and redirect physical activities. Third, the tool social media is as not exclusive to potential perpetrators of unlawful action, but is as well available to law enforcement authorities. Yet, efficient utilization of social media requires a deep understanding of its nature and a well-crafted, comprehensive approach. Acknowledging the broad functionality of social media, as well as its current status in the society, this article describes a model process for security authorities and law enforcement work with social media in general and security services work in particular. The process is cyclic and largely modular. It provides a set of goals and tasks for each stage of a potential event, rather than fixed activities. This allows authorities to adapt the process to individual legal frameworks and organization setups. The approach behind the process is holistic where social media is regarded as both source and destination of information. Ultimately, the process aims at efficiently and effectively mitigating the risk of virtual and physical violence.

To transmit and receive data over any network successfully, a protocol is required to manage the flow. High-level Data Link Control (HDLC) protocol is defined in Layer 2 of OSI model and is one of the most commonly used Layer 2 protocol. HDLC supports both full-duplex and half-duplex data transfer. In addition, it offers error control and flow control. Currently on the market there are many dedicated HDLC chips, but these chips are neither of control complexity nor of limited number of channels. This paper presents a new method for implementing a multi-channel HDLC protocol controller using Altera FPGA and VHDL as the target technology. Implementing a multi-channel HDLC protocol controller in FPGA offers the flexibility, upgradability and customization benefits of programmable logic and also reduces the total cost of every project which involves HDLC protocol controllers.

Better Than

Simulation environment of the mobile Ad Hoc network is built by applying NS2 simulation software. The simulation data indicates that AODV routing protocol is better than DSDV in throughput, fairness and stability. In the underwater network environment where the nodes are in Low-Speed movement, the data transfer rate of AODV routing protocol is higher than AOMDV. To a certain extent, AODV is more suitable for application in underwater environments.

Game Theoretic Approach

Ad-hoc networks are attractive, since they can provide a high level of connectivity without the need of a fixed infrastructure. Nodes that are not within the same transmission range communicate through multi-hops, where intermediate nodes act as relays. Mutual cooperation of all the participating nodes is necessary for proper operation of MANET. However, nodes in MANET being battery-constrained, they tend to behave selfishly while forwarding packets. In this paper, we have investigated the security of MANET AODV routing protocol by identifying the impact of selfish nodes on it. It was observed that due to the presence of selfish nodes, packet loss in the network increases and the performance of MANET degrades significantly. Finally a game theoretic approach is used to mitigate the selfishness attack. All the nodes in MANET should cooperate among themselves to thwart the selfish behavior of attacker nodes.
