Protocol Safety
Opis:
Communication infrastructure of vehicles sub-assemblies has undergone three phases of development. The first phase was initiated by the need to reduce emission levels. The function of vehicle sub-assemblies health monitoring was introduced simultaneously. This phase took place in the 70s and 80s of the 20th century. The second phase was focused on the elimination of redundant sensors and implementation of new functions of the vehicle. This phase has been particularly noticeable since the beginning of the 21st century. At the moment, there are 2 directions of development. On the one hand, the works are being continued in the scope of autonomous movement of vehicle and, on the otherhand multimedia solutions are being introduced in order to make the time spent in a vehicle more attractive (multimedia, the Internet, …). The present study is focused on the mechanisms of protection applied in communication protocols used in vehicles. Furthermore, it contains the classification of communication methods, characteristics of the basic methods of protection incorporated in the described protocols and the practical cases of security breach. Therefore, it is possible to answer the question why it is possible for third persons to interfere into the communication network of a vehicle and to indicate potential methods of protection against the functioning disturbance in such communication networks.

Opis:
Routing Protocols are underlying principles in networks like internet, transport and mobile. Routing Protocols include a series of rules and algorithms that consider routing metric and select the best way for sending healthy data packets from origin to destination. Dynamic routing protocol compatible to topology has a changeable state. RIP and OSPF are dynamic routing protocol that we consider criteria like convergence and sending protocols traffic assessment RIP first version and OSPF second version. By the test we have done on OPNET stimulation we understood that the OSPF protocol was more efficient than RIP protocol.

Opis:
One of the most recent challenges in communication system and network system is the privacy and security of information and communication session. Blockchain is one of technologies that use in sensing application in different important environments such as healthcare. In healthcare the patient privacy should be protected use high security system. Key agreement protocol based on lattice ensure the authentication and high protection against different types of attack especially impersonation and man in the middle attack where the latticebased protocol is quantum-withstand protocol. Proposed improved framework using lattice based key agreement protocol for application of block chain, with security analysis of many literatures that proposed different protocols has been presented with comparative study. The resultant new framework based on lattice overcome the latency limitation of block chain in the old framework and lowered the computation cost that depend on Elliptic curve Diffie-Hellman. Also, it ensures high privacy and protection of patient’s information.

Opis:
Principles of good manners are associated with courtesy, politeness, tact, good behaviour standards, or savoir-vivre. They include a set of specific rules of conduct that are approved of by a given community. Because courtesy plays an important role in shaping interpersonal relations, the knowledge of etiquette by officers of the services subordinate to and supervised by the Minister of the Internal Affairs and Administration in Poland is the basis for functioning in day-to-day service. Unfortunately, the notions and principles of etiquette are often confused with the principles of an official ceremonial protocol in business pragmatics. This article features the basic principles which should be followed, and not only by every police officer. After all, ignorance of the rules of protocol may lead to our being ridiculed, along with the force which we represent, both in professional and private life.

Opis:
Mobile ad hoc networks have consisted of the nodes which are freely displaced. In other words, this network has dynamic topology. Routing protocols find route of forwarding data packets from the source node to the destination node. A routing protocol plays important role in finding the shortest time and the route path. In this paper, considering significance of the subject, attempt has been made to present a model using fuzzy logic approach to evaluate and compare two routing protocols i.e. AODV DSDV using effective factor of the number of nodes based on 2 outputs of delay and throughput rate (totally fuzzy system with four outputs) in order to select one of these two routing protocols properly under different conditions and based on need and goal. To show efficiency and truth of fuzzy system, two protocols have been evaluated completely equally using NS-2 simulator and attempt has been made to prove efficiency of the designed fuzzy system by comparing results of simulation of fuzzy system and NS-2 software.

Opis:
Steganography is a technique that allows hidden transfer of data using some media such as Image, Audio, Video, Network Protocol or a Document, without its existence getting noticed. Over the past few years, a lot of research has been done in the field of Image, Video and Audio Steganography but very little work has been done in Network Steganography. A Network Steganography technique hides data in a Network Data Unit, i.e., a Network Protocol Packet. In this paper we present an algorithm ARPNetSteg that implements Network Steganography using the Address resolution protocol. Our technique is a robust technique that can transfer 44 bits of covert data per ARP reply packet.

Opis:
Attempts were made to optimize variables affecting the yield of linseed oil biodiesel in a base catalyzed transesterification reaction. The variables studied were reaction temperature (40-70oC), catalyst (NaOH) concentration (0.1-1.5%) and reaction time (30-180 min). The conversion of linseed oil into methyl esters was confirmed through analytical methods like 1H NMR, gas chromatography (GC) and refractometer. The maximum biodiesel yield (97š1.045% w/w) was obtained at 0.5% catalyst concentration, 65oC temperature, 180 min reaction time and 6:1 molar ratio of methanol to oil. 1H NMR confirmed the practically obtained % conversion of triglycerides into methyl esters which was further evidenced by refractometer analyses. The refractive index of biodiesel samples was lower than pure linseed oil. GC analysis confirmed the presence of linolenic acid (C18:3) as the dominant fatty acid (68 wt. %) followed by oleic acid (C18:1), linoleic acid (C18:2) and stearic acid (C18:0) respectively. The physical properties of linseed oil biodiesel like specific gravity (0.90 g/cm3) and flash point (177oC) were higher than American Society for Testing and Materials standards (ASTM 6751) for biodiesel. However, kinematic viscosity (3.752 mm2/s) was in the range of ASTM standards.

Opis:
Vehicular Ad Hoc Networks (VANET) constitute a promising technology for Intelligent Transport Systems (ITS). VANET are highly dynamic in their nature because of the movements of vehicles, which are acting as nodes. The routing protocol must be designed for dealing with multiple limiting conditions, like link failures, handoffs, and long congestion periods, which is very challenging. The survey of different routing protocols in VANET provides a significant information for building smart ITS. Accordingly, the present survey is devoted to the existing distinct multipath routing protocols. This review article provides a detailed account on 50 research papers, presenting the different kinds of multipath routing protocols, namely proactive routing protocols, ad-hoc-based routing protocols, Greedy Perimeter Stateless Routing (GPSR), hybrid routing protocols, as well as geographic routing protocols. Besides the classification and cursory description, the present study addresses also several of the important parameters, like evaluation metrics, implementation tool, publication year, datasets utilized, Peak Signal to Noise Ratio (PSNR), and packet end-to-end delay with respect to various techniques considered. Eventually, the research gaps and issues of various multipath routing protocols are presented with the intention of pointing out directions for future research.

Opis:
International Society of Biomechanics has proposed a general reporting standard for joint kinematics based on anatomical reference frames. Nevertheless, the gait analysis protocols based on this standard are still poorly reported. The purpose of the current study is to propose and preliminarily assess the potential of an anatomically based ISB 6-DOF protocol, which combines the ISB reporting standard together with a marker cluster technique. The proposed technical marker set enables full description of the lower limb kinematics (including three-dimensional ankle-foot complex rotations) according to the current biomechanical recommendation. The marker set provides a clinically acceptable inter-trial repeatability and minimal equipment requirements.

Opis:
The heterogeneous mobile terminals coexist in the next generation wireless networks. The most common routing schemes for mobile ad hoc networks are designed for homogeneous wireless networks. The heterogeneous wireless network routing protocols are needed urgently in many important applications. This paper improves the routing scheme utilizing different capability of terminals and the Hybrid Grid Routing Protocol (HGRP) is proposed. The network is organized in the grid form, that is, the network deployment area is divided into square cells according to the location. Each cell contains one backbone node and several ordinary nodes. This proposed protocol consists of four parts: grid construction, local routing, global routing, and routing correction. Analysis and simulation results indicate that the proposed protocol has the advantages of lower routing cost, lower energy consumption, smaller delay and higher throughput, compared to AODV and ZRP.

Objectives: A protocol for training in cardiopulmonary resuscitation in football is proposed. The protocol aims to train professionals in the field of football, as well as assess whether their training has been effective. The final objective is that, if necessary, they are able to carry out an intervention prior to the arrival of specialized care. Methods: The protocol is aimed at professionals in the field of football, as coaches or assistants, among others. The protocol consists of three phases: 1) Initial evaluation. 2) Training 3) Final evaluation. To obtain a positive evaluation, the participants must obtain a positive evaluation in all the evaluation criteria. Findings: It is expected that the percentage of participants with a positive evaluation after the training is significantly higher (p <0.05) than the percentage of participants with a positive evaluation before training, a result that will confirm the effectiveness of the proposed protocol for training on cardiopulmonary resuscitation in football. Conclusions: This protocol could be extrapolated to other sports and situations outside the sports field, such as shopping centers or schools.

Opis:
Compared with traditional cellular networks, wireless ad hoc networks do not have trusted entities such as routers, since every node in the network is expected to participate in the routing function. Therefore, routing protocols need to be specifically designed for wireless ad hoc networks. In this work, we propose an authenticated routing protocol based on small world model (ARSW). With the idea originating from the small world theory, the operation of the protocol we proposed is simple and flexible. Our simulation results show the proposed ARSW not only increases packet delivery ratio, but also reduces packet delivery delay. In particularly, Using authentication theory, the proposed ARSW improves communication security.
