The Internet of Vehicles (IoV) is a technology that combines the Internet of Things and an intelligent transportation system (ITS), and it is being studied to provide driver convenience and reduce traffic accidents. Autonomous vehicles use advanced driver assistance systems sensors such as cameras, riders, and radar to recognize the road environment. In addition, autonomous vehicles use a high definition map (HDmap) to search a driving route, and use vehicle to everything (V2X) communication technology to acquire external information to drive safely. However, HD-maps and V2X communication have a lot of influence on the external environment. To solve this problem, a scheme for applying a wireless sensor network (WSN) to an ITS has been proposed. WSNs can detect wild animals, so building infrastructure in wild animal haunting areas can prevent road kills caused by autonomous vehicles. However, the sensor node of a WSN is deployed outside and has the disadvantage of being vulnerable to security because it uses wireless communication. If a black hole attack is attempted on the WSN used for the IoV, the message may not be delivered and damage from a car accident may occur. To solve this problem, the IoV must be efficiently authenticated using public keys, and WSN must detect and respond to attacks to deliver accurate information. The proposed scheme prevents accidents by detecting a black hole attack through base station and initializing the damaged node by performing secondary verification through the IoV. The proposed scheme evaluates the performance by simulation using discrete event system specifications. The proposed scheme shows a detection rate of 70% when a black hole attack is attempted with 87.0414% probability through the experimental results. Keywords— Discrete Event System Specification; Internet of Vehicle; Network Security; Wireless Sensor Network

Wireless sensor networks (WSNs) self-organize clusters via communication between multiple sensor nodes that are deployed across a large field and an open environment. Therefore, nodes can be easily compromised, and attackers can launch false report injection attacks through compromised nodes. Several security protocols based on a message authentication code (MAC), such as the Probability Voting based Filtering Scheme, have been proposed to prevent application-layer attacks. MAC-based protocols remain vulnerable to high-level attacks where all MACs have false event values. We propose a temporal logic-based security model that allows the base station to defend against false report attacks by executing report authenticity detection using a temporal logic

Currently, three-dimensional (3D) printing is being widely used for rapid pro-totyping and Just in Time manufacturing. Many commercial 3D printers use fused filament fabrication (FFF), a printing technique where a solid thermo-plastic filament is melted and extruded onto sequential two-dimensional layers to produce a 3D object. In FFF printing, thermal stresses between layers due to inhomogeneous thermal conduction during cycles of heating and cooling create distortions, known as warpage. Process variables, especially infill density and infill pattern, cause thermal properties to become anisotropic because of thermal conduction through plastic and natural convection in air gaps. In order to identify the effect of these process variables on thermal warpage, Polylactic Acid (PLA) discs with varying infill densities and patterns were printed and the spatiotemporal temperature distribution was modeled. Trajectory similarity analysis using the Dynamic Time Warping algorithm as well as a temperature gradient analysis with statistical tests were conducted. Based on the analysis of the data, this study recommends that 30% infill density and trihexagonal infill pattern be used in FFF printing with PLA to mitigate the warpage. Keywords—Warpage; fused filament fabrication; infill; temperature distribution; thermal stress; dynamic time warping

Soil improvement is a major factor considered when dealing with weak soils for engineering purposes. This report presents the various tests conducted on fiber-reinforced soil with varying fiber content and different aspect ratios. Strips of wastewater sachets were used as a reinforcement material to perform the strength test on the soil. Several Compaction and California Bearing Ratio (CBR) tests were conducted on randomly reinforced soil by alternating the aspect ratio or sizes of plastic strips. The aspect ratios used were 15x10 mm, 15x20 mm and 15x30 mm. The CBR value obtained for the unreinforced soil was 6.85%. The CBR values obtained for the reinforced soil with the plastic fiber of sizes, 15x10 mm, 15x20 mm, and 15x30 mm were 9.31%, 16.91%, and 17.57% respectively. The CBR test results showed that the reinforcement benefit increased with an increase in aspect ratio. Hence, appropriately cut strips of wastewater sachets with optimum sizes would prove useful for soil improvement if mixed with locally available soils in an appropriate quantity. The proposed technique is recommended for embankment/road construction, industrial yards among others.

– Identifier Locator Network Protocol (ILNP) is one of the prominent solutions to enhance Internet architecture and overrun current challenges. It is a Host-based Identifier/ Locator Split Architecture scheme that operates based on address rewriting. In order to perform address rewriting, each ILNP host uses a network layer logical cache to store state information related to the communicated hosts called Identifier Locator Communication Cache (ILCC). As ILCC plays a fundamental role in every ILNP packet transmission and reception, it must adopt an effective policy to ensure high network stack performance. In this paper, we discuss ILNP caching and its role in performing ILNP operations. As ILNP caching operate at the network layer, we survey the gain from this caching with different transport layer protocols scenarios. After that, we propose a novel approach to implement ILNP caching policy using three-way handshake mechanism between communicated peers. The proposed approach is evaluated after being implemented in Linux OS kernel, and its performance is compared with other implementation. The obtained results show that our policy keeps network stack execution time at average values and enhances host immunity against denial of service attacks that may target network layer sessions.
