The goal of Quality of Service (QoS) routing algorithms is to find a feasible path satisfying a given set of constraints on parameters like delay, jitter and reliability and so on and one of the key issues in providing end-to-end QoS guarantees in packet networks is determining feasible path that satisfies a number of QoS constraints. We present our algorithm Optimized Multi-Constrained Routing (OMCR) for the computation of constrained paths for QoS routing in packet switched networks. OMCR applies distance vector to construct a shortest path for each destination with reference to a given optimization metric from which a set of feasible paths are derived at each node. OMCR is able to find feasible paths as well as optimize the utilization of network resources. OMCR operates with the hop-by-hop, connectionless routing model in Internet Protocol and does not create any loops while finding the feasible paths. © Medwell Journals, 2016.

Network connectivity is the critical issue in the internet of things. Due to the node mobility and randomly deployed nodes, the performance of the mobile ad hoc network may reduce the performance improvement. By using the proposed software-based heuristic clustered (SBHC) technique, can increase the performance of the mobile ad hoc network. This proposed SBHC technique can involve in three different stages such as clustering formation, software-based clustering, and heuristic clustered routing protocol. In clustering formation, cluster head will be selected based on the weighted clustering algorithm. Software-based clustering assigns the task scheduling and avoid the node failure. Heuristic clustering routing protocol is used to create the routing path between the cluster head, gateway and cluster members. This proposed SBHC technique, increases the network performance by using the quality of service parameters that was shown in the simulation results. © 2017 Springer Science+Business Media, LLC

Secured self organizing network is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. In delay tolerant network packets storage exists when there is any link breakage between the nodes in the network so delay is tolerable in this type of network during the data transmission. But this delay is not tolerable in wireless network for voice packet transmission. This evokes the use of wireless networks. In a network, different wireless network topologies are interoperating with each other so the communication across the network is called overlay network. This network is vulnerable to attacks due to mobile behaviour of nodes and frequent changes in topologies of the network. The attacks are wormhole attack and blackhole attack is analysed in this paper. They are critical threats to normal operation in wireless networks which results in the degradation of the network performance. The proposed recovery algorithm for wormhole and the isolation of blackhole will increase the performance of the network. The performance metrics such as throughput, packet delivery ratio, end–end delay and routing overhead of the network are evaluated. © 2017 Springer Science+Business Media New York

Pyrolysis of biomass is a means to industrially manufacture renewable oil and gas, in addition to biochar for soil amendment and long-term carbon fixation. In this work, bio oil derived from the flash pyrolysis of palmyra palm fruit bunch are analysed using gas chromatography mass spectroscopy technique. The pyrolysis oil fraction exhibits a wide variety of fatty acids, alkanes, alkenes, amides, aldehydes, terpenes, pyrrolidinines, phytol and phenols. In this work the gas chromatography–mass spectroscopy was developed and applied for the analysis of various chemicals present in the pyrolysis bio oil. More than 250 chemical compounds were identified. Most of these compounds have not been reported earlier. The increase in the number of identified chemical products is due to increased separations. The method described in this article is a suitable research tool for the determination of various chemical compounds from pyrolysis bio oil. © 2016, Sphinx Knowledge House. All rights reserved.

In wireless communication systems, mobility tracking deals with determining a mobile subscriber (MS) covering the area serviced by the wireless network. Tracking a mobile subscriber is governed by the two fundamental components called location updating (LU) and paging. This paper presents a novel hybrid method using a krill herd algorithm designed to optimize the location area (LA) within available spectrum such that total network cost, comprising location update (LU) cost and cost for paging, is minimized without compromise. Based on various mobility patterns of users and network architecture, the design of the LR area is formulated as a combinatorial optimization problem. Numerical results indicate that the proposed model provides a more accurate update boundary in real environment than that derived from a hexagonal cell configuration with a random walk movement pattern. The proposed model allows the network to maintain a better balance between the processing incurred due to location update and the radio bandwidth utilized for paging between call arrivals. © 2015 F.

Environmental and economic factors increasingly encourage higher utility of industrial by-products. The basic objective of this study was to identify alternative source for good quality aggregates which is depleting very fast due to fast pace of construction activities in India. EAF oxidizing slag as a by-product obtained during the process in steel making industry provides great opportunity to utilize it as an alternative to normally available coarse aggregates. The primary aim of this research was to evaluate the physical, mechanical, and durability properties of concrete made with EAF oxidizing slag in addition to supplementary cementing material fly ash. This study presents the experimental investigations carried out on concrete grades of M20 and M30 with three mixes: (i) Mix A, conventional concrete mix with no material substitution, (ii) Mix B, 30% replacement of cement with fly ash, and (iii) Mix C, 30% replacement of cement with fly ash and 50% replacement of coarse aggregate with EAF oxidizing slag. Tests were conducted to determine mechanical and durability properties up to the age of 90 days. The test results concluded that concrete made with EAF oxidizing slag and fly ash (Mix C) had greater strength and durability characteristics when compared to Mix A and Mix B. Based on the overall observations, it could be recommended that EAF oxidizing slag and fly ash could be effectively utilized as coarse aggregate replacement and cement replacement in all concrete applications. © 2015 Alan Sekaran et al.

Construction industry has accomplished extensive growth worldwide particularly in past few decades. For a construction project to be successful, safety of the structures as well as that of the personnel is of utmost importance. The safety issues are to be considered right from the design stage till the completion and handing over of the structure. Construction industry employs skilled and unskilled labourers subject to construction site accidents and health risks. A proper coordination between contractors, clients, and workforce is needed for safe work conditions which are very much lacking in Indian construction companies. Though labour safety laws are available, the numerous accidents taking place at construction sites are continuing. Management commitment towards health and safety of the workers is also lagging. A detailed literature study was carried out to understand the causes of accidents, preventive measures, and development of safe work environment. This paper presents the results of a questionnaire survey, which was distributed among various categories of construction workers in Kerala region. The paper examines and discusses in detail the total working hours, work shifts, nativity of the workers, number of accidents, and type of injuries taking place in small and large construction sites. © 2015 S.

The oil obtained by pyrolysis of waste plastics can be used as an alternate fuel for diesel engine without making any modification to the engine. The WPPO (waste plastic pyrolysis oil) mixed with 5% and 10% DEE (diethyl ether) were used as fuels for single cylinder water cooled, DI engine and its performance, emission and combustion characteristics were found. The experimental results indicated the reduction in smoke levels with that of baseline waste plastic pyrolysis oil. The BTE (brake thermal efficiency) increased when compared to pure plastic pyrolysis oil and diesel. The pollutants such as CO (carbon monoxide) and NOx (nitrous oxide) were reduced in the blend. It was observed that addition of oxygenates had improved the combustion process and reduced the emissions. The investigation revealed that blending of DEE with plastic oil increases the Cetane rating which is superior to neat diesel. © 2015 Elsevier Ltd.

This paper describes an experimental study of using polymer oil obtained from the plastic waste as a fuel in diesel engine. In this study, the effects of using polymer oil - ethanol fuel blends [PE10, PE20] on the engine performance, exhaust emissions and combustion characteristics have been experimentally investigated. In the present work, 10% ethanol and 90% polymer oil, called here as PE10 and 20% Ethanol and 80% polymer oil called here as PE20 were used in a single cylinder four stroke, water cooled diesel engine. The engine fuelled by the blends is comparable with that fuelled by diesel. The experimental result showed that the carbon monoxide, carbondioxide, Oxides of nitrogen and smoke were significantly reduced. Unburned hydrocarbon, brake specific fuel consumption and brake thermal efficiency were found to have increased with ethanol-polymer oil blends. © 2013 Praise Worthy Prize S.r.L-All rights reserved.
