Mobile Ad-hoc Network (MANET) is a group of mobile nodes with changing topological network structures. The mobility of nodes affects the energy level of these nodes which further affects the different QoS parameters of MANET like average delay, Packet delivery ratio, Average throughput etc. At the same time, malicious nods might execute an attack by flooding the network with wrong data or by forestalling different nodes from getting a complete network topology map which further affects QoS parameters. The proactive protocols like OLSR, TORA, AODV etc. are not designed to address these network and security issues at the same time. In this paper, a new hybrid approach is proposed to ensure secure video streaming over MANET that can optimize delay and energy utilization in OLSR, by considering the mobility of nodes as well as to improve the security by dealing with different malicious node attacks like wormhole, black hole and packet replication, that can be achieved with encryption techniques like AES, digital signature etc. [ABSTRACT FROM AUTHOR]

As a computer programmer, a smart contract encapsulates the contractual features of the parties' transactions through code. Some blockchain technology platforms, such as Hyperledger Fabric, IBM Blockchain and Ethereum, currently allow smart contracts. Smart contracts on these platforms are kept on the blockchain and are not under the control of any party involved. They can't be tampered with after they've been digitally signed and placed on the blockchain. The use of smart contracts in blockchains is critical. It is the authors' primary goal with this research to provide an alternative to standard contracts by allowing users to modify data stored in the chain. Methodology for designing smart contracts is presented in this article, along with an example of how it has used modifications to the data stored in the chain. In this article, we present a methodology for the design of smart contracts and we also illustrate its application with a case study. [ABSTRACT FROM AUTHOR]

Blockchain technology is current and renowned economic technology that totally transforms the business connections. Its equipment is dispersed as a proceeding of statistics contains complete particulars of the statement approved exposed and dispersed in the middle of the nodes instant in the system. With the express enlargement of communication technologies, the Internet of Things (IoT)is receiving out of its formative years, into full development, and tends to be residential in an explosively speedway, by more and more data transmit and process. All the proceedings approved, exposed in the organization are established by compromise mechanism and the information formerly stored cannot be distorted. Blockchain expertise is the essential technology in the wake of Bit coin, which is a well-liked digital crypto currency. Cloud compute is a carry out off with a set of connections of secluded server hosted on the internet to hoard, deal with, and progression figures, relatively than a general server or a special computer.' In this framework, blockchain provide novel solution to take in hand challenge in cloud of effects in terms of devolution, statistics solitude along with system safety, although Cloud of Things offers suppleness and scalability functionalities to get better the competence of blockchain operation. So, a work of fiction example of blockchain and Cloud of Things addition, called BCoT, has been extensively regarded as a capable enabler for a broad range of request scenario. In this paper, we analyse as state-of-the-art evaluation on the blockchain assimilation to make available general reader with an impression of the blockchain in a range of aspect, together with back drop information, enthusiasm, and included architecture.

Internet of Things (IoT) connects many physical devices to many individuals from earth to space. This new concept covers almost all applications such as smart cities, industries, autonomous systems, and underground setups. This article summarizes the application of IoT-driven wireless nodes and IoT decision support platform in underground mining areas where location estimation of the miners is a critical task for the mining administrators. The underground mining accident is one of the most critical environmental disasters where life risk of the miners is a very crucial factor to be addressed. There are very few research work reported to find real-time location of the miner without any Global Positioning System (GPS) and mobile signals. This work demonstrates an efficient local positioning mechanism where low-cost and high battery capacity WiFi nodes are used to find the location of the miner during crude environmental conditions. The whole local positioning system works on the basis of Receiver Signal Strength Indicator (RSSI) value of the miner nodes. This article also demonstrates the useful technique to increase the battery life more than one year. Apart from all the above technological uses, it has been proposed that the localization algorithm can be used as potential technological key for local positioning in underground mines.

Agriculture is a basic and most important profession of any country as it balances the food requirement and also the essential raw materials of industry. In the similar sense, the adaptation of implementing smart technology in agriculture practices needs to be focused on better land productivity. The fertilizer and manure should be precisely applied during agriculture practice throughout the countryside with the use of digital technologies. This motivates us to develop a reactive web application which will accurately predict the required soil N-P-K (Nitrogen- Phosphorus-Potassium) content by utilizing one time soil testing results of available soil N-P-K contents as per the yield target. This predictive model is designed by considering standard experimental data sets from Indian Council for Agriculture Research (ICAR), India. The prediction model is designed using Random Forest (RF) algorithm which is capable of handling large dataset. The predicted N-P-K content are shown in a reactive R Shiny user interface to notify required N-P-K values for the necessary action by the farmer. The complete web based prediction model is efficiently conveying the required N-P-K content information of the particular farm location to the farmer as well as the agriculture specialists.

In the early days of the web, content was designed and hosted by a single person, group, or organization. No longer are WebPages increasingly composed of content from myriad unrelated "third-party" websites in the business of advertising, analytics, social networking, and more. We provide a description of the limitations, requirements, and security models specific to Web client authentication. We propose a set of hints for designing a secure client authentication scheme. Using these hints, we present the design and analysis of a simple authentication scheme secure against forgeries by the interrogative adversary. [ABSTRACT FROM AUTHOR]

Rapid advance of computer technologies in data processing, collection, and storage has provided unparalleled opportunities to expand capabilities in production, services, communications, and research. However, immense quantities of high-dimensional data renew the challenges to the state-of-the-art data mining techniques. Artificial Bee Colony (ABC) is a popular meta-heuristic search algorithm used in solving numerous combinatorial optimization problems. Feature Selection (FS) helps to speed up the process of classification by extracting the relevant and useful information from the dataset. FS is seen as an optimization problem because selecting the appropriate feature subset is very important. Classifier Ensemble is the best solution for the pitfall of accuracy lag in a single classifier. We first briefly introduce the concept of data mining and key components of feature selection. This paper proposed a hybrid approach for the feature selection by using artificial bee colony and particular swarm optimization. The proposed technique is simulated using the WEKA and results show the better performance of the proposed technique. [ABSTRACT FROM AUTHOR]
