Abstract

A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions. Providing end-to-end data security in wireless sensor network (WSN) is a non-trivial task. In addition to the large number and severe resource constraint of sensor nodes, a particular challenge comes from potential insider attacks due to possible node compromise, since a WSN is usually deployed in unattended/hostile environments. Compromised node and denial of service are two key attacks in Wireless Sensor Network (WSN). Here, we study the data delivery mechanisms to overcome these attacks with high probability of circumventing black holes. Classic multipath routing approaches are vulnerable to such attacks, mainly due to their deterministic nature. Once the adversary acquires the routing algorithm, it can compute the same routes known to the source and make all information sent over these routes vulnerable to its attacks. In this paper, we develop mechanisms that generate randomized multipath routes. Under our designs, the routes taken by the “shares” of different packets change over time. So even if the routing algorithm becomes known to the adversary, the adversary still cannot pinpoint the routes traversed by each packet. Besides randomness, the generated routes are also highly dispersive and energy efficient, making them quite capable of circumventing black holes.

Abstract

This paper presents two criteria for evaluating the motoring operations of switched reluctance hub motor (SRM) drives for electric vehicles (EVs). They imply motoring torque and copper loss. To fulfil the best motoring operation, by using two weight factors and two base values, the developed optimization function selected as the correct balance between the maximum average torque and the maximum average torque per copper loss. The stator and rotor pole arc angles are selected as the optimized variables. Simulations results have demonstrated the proposed optimal design method. Therefore, this paper offers a valuable and feasible approach for implementing the best motoring operation of SR Hub Motor drives for EVs.

Abstract

Web applications consist of several different and interacting technologies. These interactions between different technologies can cause vast security problems. As organizations are taking their businesses online they make their systems accessible to the world. They might have a firewall in place and possibly even their web server is running an up-to-date version of its software but that is not enough to protect their resources. Web applications become integral part in our day today life. Recent studies proves that more than fifty percent of the cost of software development is expend towards for testing, even though the software web applications is not free from its critical issues. Vulnerabilities provides more critical outcome in web applications instead in various researches have been involved with major impact of vulnerabilities. Recently the web applications are tested with minimal parameters. The main objective of proposed work is to reduce the time consumption and high cost for software testing. And in this paper we also tell about other possible vulnerabilities and their control measures. Using static analysis the critical vulnerabilities are analyzed where the issues are arising in web applications. The critical vulnerabilities such as handling catch block, encrypted password, execution failure in exception handling and redirecting the values of parameter. Depends on the severity of the issues the vulnerabilities are classified with the solutions.

Keywords

Cross-Site Scripting (XSS), Empty Catch Block, Open Redirect SQL Injection, Storing Passwords in a Recoverable Format, Uncaught Exception.

Abstract

Mobile technologies are increasingly growing in developing countries like India Mobile healthcare provision in the home environment presents many challenges. Mobile Healthcare is a term used for the practice of medicine and public health supported by mobile devices. It is most commonly used in the reference to using mobile communication devices such as mobile phones, tablet & computer PDAs. Nowadays, mobile has become a prominent tool, not only in urban regions but also in remote and rural areas. Mobile healthcare, in the home environment presents many new challenges. A wireless sensor network with a large number of sensor nodes can be used as an effective tool for gathering data in mobile healthcare situations. The work includes a detailed study of mobile healthcare system in various aspects. Various algorithms and techniques, for effective healthcare are addressed in this paper. After analyzing, the survey is concluded with several promising directions for further research in mobile healthcare system.
