Nowadays communication and data transmission among various heterogeneous networks is growing speedily and drastically. More number of heterogeneous networks are created and deployed by government as well as by private firms. Due to the distance, mobility, behavior of nodes in the networks and dynamic in nature, it is essential to provide security for all the networks separately or distributed. Various existing approaches discuss about the security issues and challenges for heterogeneous networks. In this paper a Leader Based Intrusion Detection System [LBIDS] is proposed to detect and prevent DOS as well as other attacks such as Sybil and Sinkhole in the networks by deploying the Leader Based Intrusion Detection System into access points in the networks. The proposed approach utilizes three core security challenges such as Authentication, positive incentive provision and preventing DOS. In addition to that it will do packet verification and IP verification for improving the efficiency in terms of detection and prevention against attacks in heterogeneous networks. The simulation of our proposed approach is carried out in NS2 software and the results were given. © 2015 IEEE.

Wireless sensor networks are highly indispensable for securing network protection. Highly critical attacks of various kinds have been documented in wireless sensor network till now by many researchers. The Sybil attack is a massive destructive attack against the sensor network where numerous genuine identities with forged identities are used for getting an illegal entry into a network. Discerning the Sybil attack, sinkhole, and wormhole attack while multicasting is a tremendous job in wireless sensor network. Basically a Sybil attack means a node which pretends its identity to other nodes. Communication to an illegal node results in data loss and becomes dangerous in the network. The existing method Random Password Comparison has only a scheme which just verifies the node identities by analyzing the neighbors. A survey was done on a Sybil attack with the objective of resolving this problem. The survey has proposed a combined CAM-PVM (compare and match-position verification method) with MAP (message authentication and passing) for detecting, eliminating, and eventually preventing the entry of Sybil nodes in the network. We propose a scheme of assuring security for wireless sensor network, to deal with attacks of these kinds in unicasting and multicasting. Copyright © 2015 U. S. R. K. Dhamodharan and R.

In this study, the effect of geometry on the performance of a tetrahedral solar still was experimentally investigated on Chennai climatic conditions. In this work, a solar still of area 0.95 m2 and a glass cover in a triangular form was designed and fabricated. Environmental parameter includes solar intensity, ambient temperatures, and wind speed. Operational parameters are feed water quantity and orientation. Tests were conducted in Hindustan Institute of Technology and Science, Kelambakkam, Chennai, India. The maximum distillate output found was 4.3 lm-2day-1. The results shows that the production of fresh water was increase up to 40% compared to that of other conventional solar stills.

In this paper, a new model portable solar still is designed, fabricated and tested in the summer conditions of Chennai climatic condition. The phase change material is used in order to divide a single slope portable solar still into evaporating and condensing chambers. The result shows that a maximum efficiency of 14% of the solar still with phase change material is achievable. The accumulated yield and obtained with PCM is 52% more efficient than accumulated yield obtained without PCM. The still continues to produce fresh water after the sunset. More than 34% of total water production is pertaining to this time. © 2015 Elsevier B.V.

Mobile Ad hoc networks have invaded some of the most traditional technologies due to the portability that comes handy with efficient communication using the 'temporary links' created between the nodes. One of the major issues face, however, is the link failure issue during the movement of nodes. In this study, we provide a solution to perform efficient multicasting in MANETs called Link Based Route Selection for Multicasting (LBRSM) with the link conditions considered as well. ϕ is a novel link factor proposed that aids in choosing the best next node to reach the destinations while multicasting. The efficiency of the proposed method is evaluated by the simulations in network simulator. To prove the efficiency, we compare the simulations results of LBRSM and LSMRP to show that the LBRSM is efficient. © Maxwell Scientific Organization, 2015.

CdS nanocrystals were synthesised by a simple and novel solvothermal method using a domestic microwave oven. X-ray diffraction measurements indicate that, for all the three molecular ratios (1:1, 1:2 and 1:3) of reactants considered, the crystallite size is controlled to less than 14 nm. UV visible absorption spectral measurements show an optical bandgap within the range of 2.62-2.77 eV. Energy dispersive X-ray absorption spectral, DC and AC (with a fixed frequency of 1 kHz) electrical (at various temperatures ranging from 40-110°C) measurements were also carried out on all the three samples prepared. The results obtained indicate that the electronic contribution plays a dominant role in charge transport process and polarisability. © 2011 Published by Elsevier Ltd.

A modified architecture for minimized power dissipation in the maximum a posteriori (MAP) decoder based on clock gating and toggle filtering is proposed in this paper. Log likelihood ratio (LLR) in the trellis structure of the MAP decoder consumes large power. To minimize the power dissipation, toggle-filtering technique is introduced in the LLR unit of MAP decoder and clock-gating approach is introduced in the state metric, branch metric and again in LLR blocks of the MAP decoder. Toggle filter is used to avoid early injection of signals from the state metric and branch metric units. Clock-gating approach is used to keep the idle block in the disabled state. A power dissipation of 53.64 % has been achieved when toggle-filtering technique is applied and 54.4 % when clock-gating technique is applied. Power dissipation of 64.07 % has been achieved for the combined effect of toggle-filtering and clock-gating technique. © 2015, Springer Science+Business Media New York.

Transportation safety is an important factor in the Intelligent Transportation System (ITS) applications. Vehicle accidents, road conditions and traffic conditions are the major issues in the transportation system. Around 1200 road crashes occur daily in India and around 350 people die daily due to road accidents. In this paper we are going to implement a solution to avoid the cited issues through a concept of Internet of Vehicles (IoV). The cited issues can be solved by exchanging the internal and external datas of a vehicle connected to a network. The vehicles connected in that network can transmit and receive its datas such as speed, position, direction and traffic between them. The Sharing of datas is done by using a cloud network, in which all the datas will be stored and transferred to vehicles. This allows us to make a safety transportation system. © International Science Press.

Pollution from different sources affects peoples around environment. This paper deals with a simple case study presenting a regression analysis for noise levels generated from different sources in Chennai, Tamil Nadu, India. Two sets of Leq noise levels were recorded from selected places at an intersection near National Highway 4 were (97.9dBA and 98.9dBA) and other district road near Avadi was (56dBA and 57.8dBA). The data set consists of around 2500 measurements measured on two days. Apart from collecting noise data we have collected some of the noise producing parameters like speed of vehicle, mode of vehicles and distance of measurements. The first set data is used for prediction of noise levels show a variance of ±1.18% dBA for the developed Leq model. The second set of data is used for validating the above model which shows an adoptability of around 95% on predicting noise levels. The developed model can be used in traffic stream to predict noise levels. © International Science Press.
