Blockchain technology is widely known because it is the underlying technology used by the bitcoin. It became more popular because it also can be used as backbone for various applications in finance, media, security and others. One of the main concerns for this technology is how secure the information that the users distributed over the network. This paper studies and highlights the important security issues concerned and discusses the solutions that proposed by the researchers and theoretical solution proposed to address some of the issues. However, this approach needs to be investigated further if it is to be implemented later in the near future. This paper can give direction for future researchers who are interested of this area.

Internet of Things enabled Intra-Vehicular Network (IVN) refers to the network where large number of sensors are connected with each other for sharing the vehicles status information in order to develop a smart vehicular system. The number of sensor nodes in the vehicle has increased significantly due to the increasing vehicular applications. The phenomenon of congestion poses a problem in the IVN where the traffic load and number of sensors are increased. This problem can be resolved by mitigating the limitation of the existing Media Access Control (MAC) protocols. In this paper, we address this issue and proposed a MAC strategy for solving this problem in this network. Furthermore, we discuss the design of IVN scenario and the performance is evaluated in terms of end-to-end delay. The simulation results reveal the effectiveness of our proposal.

Due to rapid population growth, the demand for food is also elevating, which inspires farmers to embrace precision agriculture to increase production by exploiting predictive analytics on relevant real-time data. The exactitude of a prediction is vital to decide the next course of actions to be taken to compensate current demands, which again relies on a competent data acquisition technique. The Media Access Control (MAC) protocols have significant contribution in designing data acquisition technique. In this paper, we propose a new Store-and-Delivery base MAC (SD-MAC) protocol for Air-Ground Collaborative Wireless Networks (AGCWNs) to acquire data efficiently from the sensing devices which are deployed in the agricultural field. Our proposed protocol takes into consideration of the factors of network architecture and transforms them into advantages to attain higher throughput. The performance of the proposed protocol is evaluated using simulations and involving another such protocol, where the proposed protocol outperforms the other protocol.

Wireless networks play a vital role in shaping today’s network infrastructure. Although in the past, the use of wireless communications was limited to the last-mile connectivity of the network, their convenience and adaptability has led to a variety of innovative wireless technologies that are now arriving at the scene. These include mobile technologies, 4G (LTE, WiMAX), 3G (UMTS, HSPA), Bluetooth, wireless sensor network (WSN), radio frequency identification (RFID), nearfield communication (NFC), mobile ad hoc network (MANET), vehicular ad hoc network (VANET), wireless mesh network (WMN), wireless body area networks (WBAN), and Wi-Fi. An amalgamation of these different technologies will dramatically enhance the usefulness of small-sized Internet-capable devices and potentially would offer a world of truly ubiquitous computing.

Due to recent advancements and appealing applications, the purchase rate of smart devices is increasing at a higher rate. Parallely, the security related threats and attacks are also increasing at a greater ratio on these devices. As a result, a considerable number of attacks have been noted in the recent past. To resist these attacks, many password-based authentication schemes are proposed. However, most of these schemes are not screen size independent; whereas, smart devices come in different sizes. Specifically, they are not suitable for miniature smart devices due to the small screen size and/or lack of full sized keyboards. In this paper, we propose a new screen size independent password-based authentication scheme, which also offers an affordable defense against shoulder surfing, brute force, and smudge attacks. In the proposed scheme, the Press Touch (PT)—a.k.a., Force Touch in Apple’s MacBook, Apple Watch, ZTE’s Axon 7 phone; 3D Touch in iPhone 6 and 7; and so on—is transformed into a new type of code, named Press Touch Code (PTC). We design and implement three variants of it, namely mono-PTC, multi-PTC, and multi-PTC with Grid, on the Android Operating System. An in-lab experiment and a comprehensive survey have been conducted on 105 participants to demonstrate the effectiveness of the proposed scheme.

Since fairness deals with the quality of distributing the jobs and creates an ambience that is free from any discrimination, any distribution management problem must take fairness issue into consideration. Again, since the Vehicle Routing Problem (VRP) is also a distribution management problem, any VRP solving algorithm must consider the fairness when solutions are explored. However, most of the proposed VRP solving algorithms do not take this issue into consideration. In this paper, we raise this issue with sufficient evidences. In this course of action, following contributions are made in this paper: i) fairness issue is raised analytically, and to support this, an extensive simulation campaign is performed, ii) the VRP is discussed through a practical application, namely Garbage Collection Problem (GCP), and later it is mathematically formulated, iii) a Genetic Algorithm (GA) is employed to explore feasible solutions for the given application (i.e., GCP), and iv) some future research directives are noted, which will help the researchers to extend this work.
