Mobile Ad Hoc Network (MANET) is collection of multi-hop wireless mobile nodes that communicate with each other without centralized administration or fixed infrastructure or permanent topology. Routing protocols developed for wired networks are inadequate as they not only assume mostly permanent topology but also having high overheads. This problem leads to several routing algorithms/proposals specifically for ad hoc networks. However, some of these proposals are optimized variants of protocols designed for wired networks. This paper focused on various On Demand Routing protocols known as reactive protocols such as DSR, AODV, TORA, ABR, DYMO, LMR, LAR, SSA CBRP, RDMAR, MSR, AOMDV, ARA and their comparison with advantages and disadvantages.

In this paper, Smart Card based Online Health Care System with low cost Audio and Video Facilities have been discussed. For providing a good quality of treatment to the patients in the hospital, it is required to automate and integrate the hospitals of country via internet. After registration, patient will get a smart card with 10 digits unique registration number/ PatientID with personal information in the hospital. All the doctor prescriptions, test reports (blood, urine etc), images (MRI, CT-Scan, ECG etc.) will be stored in the databases of the hospital server (local server) as per the PatientID. All the local servers of hospitals are connected with one centralized server and time to time all the patient data from the local hospital server will be transferred to main centralized server. Patient information, doctor information and hospital information etc. can be retrieved from any hospital of any patient as per the PatientID. There may be a situation where patient is present in a rural hospital where sufficient expert doctors are not available. In such situations, doctor present in the remote hospital may need to contact an expert to take his advice for better treatment of the patient. In this work, a Graphical User Interface for low cost Videoconferencing System for Online Health Care System is also discussed, specifically to support consultations among remotely placed Patients, rural health workers and specialists in the urban cities and provide a secure access to remote patient records. A low-cost web-based Videoconferencing System using Open Source Technologies such as Red5 etc. has been developed. We have used live video/audio, text chat and video recording/archiving tools and features for the same. Online Health Care System application has been developed as front end in DOT NET [4] and back end in SQL Server. SQL Server tuning & other features are implemented for fast retrieval of patient data while designing the application of Health Care System.

This research focused on the impacts of information and communication technology in facilitating the education of students with visual impairment. This work reviews the existence of information and communication technology (ICT) in educating the students with visual impairment in Federal College of Education (Sp.), Oyo, Oyo State, Nigeria, and to investigate further, the impact of ICT on academic performance of students with visually impaired. Fifty (50) students with visual impairment at the Federal College of Education (Sp.), Oyo, State, Nigeria were randomly selected and questionnaires were administered to them. Data were extracted from the questionnaires and analyzed. The results showed that students with visual impairment greatly benefited from integration of ICT with visually impaired education. Integration of ICT with visually impaired education significantly enhanced the academic performance of students with visual impairment. Government should support education of students with visually impaired so that they can have independent and meaningful lives and to put a stop to roaming about the streets begging for survival.

Due to public location and permanent availability multiple people depends on the automated teller machine (ATM). Due to that they can easily fall victim to manipulation. Frauds and security attacks based on observation by person or via various cameras also get increased. So, new methods for authentication mechanisms get developed to reduce the ATM security problems related to personal identification numbers (PIN). The user’s mobile phones play a central role in the trust establishment. Shift PIN entry away from possibly insecure ATMs PIN pad towards the user’s mobile phones & then transmit it securely for authentication. Dual tone modulated frequency (DTMF) plays a major role in this technique.

This paper discusses the potential of using technologies in the diagnosis, study and intervention treatments of autism. The first part of paper introduces background information on autism spectrum disorder. The second part deals with review of literature survey. The third part summarizes our proposed research work on the connected topic. The fourth part concludes our work as whole.

Program Slicing is a method for automatically decomposing programs by analyzing their data flow and control flow. Slicing reduces the program to a minimal form called “slice” which still produces that behavior. Program slice singles out all statements that may have affected the value of a given variable at a specific program point. Slicing is useful in program debugging, program maintenance and other applications that involve understanding program behavior. This paper is a review paper on program slicing.

Data worldwide is growing 40 percent per year, a rate of growth that is daunting for any organization. Big Data Analytics is becoming an increasingly important part of every aspect, batch processing system like Hadoop had evolved for excellent offline data processing platform for Big Data. There are many use cases across various domains which require real-time / near real-time response on Big Data for faster decision making. This paper describes beyond batch processing system towards Real-Time and Streaming.

Due to the wide acceptability of the industry for cloud computing, variety of applications are designed targeting to cloud platform which makes efficient load balancing a major bottleneck for the above. To improve the efficiency of the cloud platform, a judicial distribution of workload among the available resources needs to be ensured. To share the workload in an effective way, a proper load balancing strategy is important. This strategy comprises of information policy, triggering policy, resource type policy and selection policy. Since cloud applications are running in a distributed scenario, through this paper, researcher suggests a selection policy for load balancer in a distributed environment.

This paper untangle the idea of software security and applying sound practices to the phases of software development life cycle that design and develop software and subject all phases to risk analysis and testing. It focuses on importance of secure software and unveils why and how attackers target software. It brings into light some of the exploitable software defects and certain methods to make software less vulnerable to attacks. It also presents the idea of software testing and its goal with the perspective of considering security as an important requirement to test.

In Classical Hypothesis testing volumes of data is to be collected and then the conclusions are drawn, which may need more time. But, Sequential Analysis of Statistical science could be adopted in order to decide upon the reliability / unreliability of the developed software very quickly. The procedure adopted for this is, Sequential Probability Ratio Test (SPRT). It is designed for continuous monitoring. The likelihood based SPRT proposed by Wald is very general and it can be used for many different probability distributions. In the present paper we propose the performance of SPRT on 5 data sets of ungrouped using delayed S-shaped model and analyzed the results. The parameters are estimated using Maximum Likelihood Estimation method.
