PROPOSED LIGHTWEIGHT PROTOCOL FOR IOT AUTHENTICATION
Get PDFThe Internet of Things (IoT) alludes to interestingly identifiable items (things) which can communicate with differentquestions through the worldwide framework of remote/wired Internet. The correspondence system among an expansive number of assetobliged gadgets that produce substantial volumes of information affects the security and protection of the included items. In thispaper, we propose a lightweight protocol for IoT authentication which based on two algorithms LA1 and RA1 which is used forauthentication and generating session key that is used for encryption
DESIGN AND IMPLEMENTATION SMART TRAFFIC LIGHT USING GSM AND IR
Get PDFThe increasing in the number of vehicles on streets has led to traffic congestion. In order to reduce the waiting timein cases of emergency, the idea of this work is suggested. This work is divided into two parts, the particular part and softwarepart. The first circular particular part is a model which consists of four lanes junction of a traffic light, it also has GSM system (Global System for Mobile Communications). The GSM and lamps of the traffic light are connected to Arduino UNO. TheArduino controls every signal which is coming from the inputs (GSM) to software and display to the outputs (lamps) Thesecond circular particular part is a model which consist same components the first circuit except replace the GSM withIR(infrared Remote).The goal from this work is to help us in the emergence cases, the opening and closing of the traffic light arecontrolled by using GSM system and IR, the time of each lane, is controlled that means reduce the crowding
DESIGN AND IMPLEMENT CHAT PROGRAM USING TCP/IP
Get PDFLAN Chat Messenger using TCP/IP offers reliability, security and zero cost communication among staff members of acompany. As well, this study offers file transfer. It helps to solve the communication problems that related to time and cost. The proposedprotocol facilitates information exchange among individuals by providing many communication options. It is a standaloneapplication using JAVA as the programming language and tested at LANs of our institute (college\u27s Labs networks)
A SUGGESTED SUPER SALSA STREAM CIPHER
Get PDFSalsa (20) cipher is speedier than AES cipher and its offered superior security. Salsa (8) and Salsa (12) are specifiedfor apps wherever the grade of security is less necessary than speed. The concept of this research is to suggest super salsakeystream utilizing various volumes matrices size (array (4, 4), array (4, 8), array (4, 16)) are used to increase the complexity ofkey stream and make it more reluctant to linear and differential attacks. Furthermore, in each iteration, the diffusion ofgenerated keystream will increase due the effect of changing the volume acting for one element of the array is not fixed. Thegenerated keys of the suggested Super SALSA keystream are depicted as simple operations and a high hardiness randomlykeystream by exceeding the five benchmark tests. Likewise, it\u27s presenting a situation of equilibrium between complexity andspeed for Salsa (8, 12 and 20)
PROPOSED APPROACH FOR IMPROVING RNA CRYPTO-KEY BASED ON POLYNOMIAL CONVOLUTION
Get PDFRandom Number Generators are fundamental toolsfor cryptography protocols and algorithms. The basic problems thatface any crypto key generator are randomness, correlations anddistribution of the state of key sequence. This paper proposed a newmethod to enhance RNA crypto key generation. It has beenimplemented by extending the crypto key by applying polynomialconvolution technique which extracts the mask filter from the sameRNA key sequence depending on the start and end codon properties.This will provide another high level of extension and generaterandom-strength crypto key. The proposal approach could passthrough the statistical measurements successfully and achieved highrate of randomness (approximated to 96%)
EFFICIENT ROUTING PROTOCOL ALGORITHM FOR WIRELESS SENSOR NETWORKS
Get PDFRecently, different applications of wireless sensor networks (WSNs) in the industry fields using different data transfer protocols has been developed. As the energy of sensor nodes is limited, prolonging network lifetime in WSNs considered a significant occurrence. To develop network permanence, researchers had considered energy consuming in routing protocols of WSNs by using modified Low Energy Adaptive Clustering Hierarchy. This article presents a developed effective transfer protocols for autonomic WSNs. An efficient routing scheme for wireless sensor network regarded as significant components of electronic devices is proposed. An optimal election probability of a node to be cluster head has being presented. In addition, this article uses a Voronoi diagram, which decomposes the nodes into zone around each node. This diagram used in management architecture for WSNs
A RADIAL BASIS NEURAL NETWORK CONTROLLER TO SOLVE CONGESTION IN WIRELESS SENSOR NETWORKS
Get PDFIn multihop networks, such as the Internet and the Mobile Ad-hoc Networks, routing is one of the most importantissues that has an important effect on the network’s performance. This work explores the possibility of using the shortest path routingin wireless sensor network . An ideal routing algorithm should combat to find an perfect path for data that transmitted within anexact time. First an overview of shortest path algorithm is given. Then a congestion estimation algorithm based on multilayerperceptron neural networks (MLP-NNs) with sigmoid activation function, (Radial Basis Neural Network Congestion Controller(RBNNCC) )as a controller at the memory space of the base station node. The trained network model was used to estimate trafficcongestion along the selected route. A comparison study between the network with and without controller in terms of: trafficreceived to the base station, execution time, data lost, and memory utilization . The result clearly shows the effectiveness of RadialBasis Neural Network Congestion Controller (RBNNCC) in traffic congestion prediction and control

CLINICAL DATA WAREHOUSE: A REVIEW
Get PDFClinical decisions are crucial because they are related to human lives. Thus, managers and decision makers inthe clinical environment seek new solutions that can support their decisions. A clinical data warehouse (CDW) is animportant solution that is used to achieve clinical stakeholders’ goals by merging heterogeneous data sources in a centralrepository and using this repository to find answers related to the strategic clinical domain, thereby supporting clinicaldecisions. CDW implementation faces numerous obstacles, starting with the data sources and ending with the tools thatview the clinical information. This paper presents a systematic overview of purpose of CDWs as well as the characteristics;requirements; data sources; extract, transform and load (ETL) process; security and privacy concerns; design approach;architecture; and challenges and difficulties related to implementing a successful CDW. PubMed and Google Scholarare used to find papers related to CDW. Among the total of 784 papers, only 42 are included in the literature review. Thesepapers are classified based on five perspectives, namely methodology, data, system, ETL tool and purpose, to findinsights related to aspects of CDW.
