There are mainly two type of networks, wired and wireless. The wireless network is much vulnerable to security attacks as compared to wired network. In wireless networks there are both active and passive attacks are possible. The man-in-middle, session hijacking is the most common active attack today life. The session hijacking attack can be generally ...

Basic characteristic of wireless networks that makes it vulnerable to attacks is its broadcast nature. Attacks are of various types that effect confidentiality and integrity of wireless network and in this paper, the authors are discussing about Jamming attacks. Jamming can stop or disrupt wireless transmission. It is interference, noise or collision at the receiver ...

In this paper, the authors are emphasizing on developing this project that will help the lecturers to take attendance easily, securely and is less error prone. For this, they are implementing software “Mobile Phone Based Attendance System (MPBAS)” based on Android Technology. They are inspired to work on MPBAS from the existing system E-Beat. MPBAS ...

Rectangular horn is one of the simplest and most widely used microwave antennas. In this paper, an electromagnetic simulator, WIPL-D is used to analyze and optimize the dimensions of the horn antenna which is based on the method of moment’s solution for computations. The standard horn antenna at 10 GHz is modeled and the radiation ...

Wireless Sensor Networks (WSNs) are comprised of thousands of sensor nodes, with restricted energy, that co-operate to accomplish a sensing task. Various routing Protocols are designed for transmission in WSNs. In this paper, the authors proposed a hybrid routing protocol: Zonal-Stable Election Protocol (Z-SEP) for heterogeneous WSNs. In this protocol, some nodes transmit data directly ...

If your AD is secure, everything is secure. Active Directory user accounts are crucial to security because they are the basis for authentication and initial access to the network, systems, and applications. And maintaining AD in a clean, organized, and secure state is a challenge for organizations. But what if you could reduce costs while ...

Opening your notebook to find a drained battery and applications such as email in the same state you left them days ago can be a real hassle and a waste of vital time especially when you’re on the go and a power outlet and reliable Internet connection aren’t available. The Dell Latitude E6430 uses new ...

Advancements in technologies, semiconductor industry and communications resulted in construction of wireless sensors. Wireless sensors are self-managing and sensing devices having the capability to communicate with each other and sink node wirelessly. The sink node can then take decision according to the application they are being used for; upon the reception of messages from node. ...

In this paper, the authors present an efficient Artificial Neural Network (ANN)-based model to estimate both azimuth and elevation arrival angles of a signal source. To achieve this goal, the ANN model is constructed using measurement data obtained by a rectangular antenna array in the space-frequency domain. Unlike classical super-resolution algorithms such as 2D music, ...

The aim of this paper is to present an implementation of a functional IEEE 802.15.7 real-time testbed based on the Software Defined Radio (SDR) concept. This implementation is built with low cost Commercial Off-The-Shelf (COTS) analog devices and the use of Universal Software Radio Peripheral version 2 (USRP2) equipment combined with a generic object-oriented framework ...

Cloud computing are Internet-based services to increase the use and delivery models, usually involving the Internet to provide easy to dynamically scalable and often virtualized resources. To solve these problems, the proposed web data mining method based on cloud computing: the massive data mining tasks decomposed into parallel processing on multiple servers. Web fuzzy clustering ...

In LTE systems, the downlink scheduler is an essential component for efficient radio resource utilization; hence, in the context of LTE simulation, the availability of good down-link scheduler models is very important. At the time this work started, the LTE module of the ns-3 simulator only supported two types of scheduler, namely Round Robin and ...

Most of the industrial processes are multivariable in nature. Greenhouse system is considered which the important application is in agricultural process. Greenhouse is to improve the environmental conditions in which plants are grown. In this paper, the authors have proposed identification of greenhouse system using input and output data sets to estimate the best model ...

The introduction of wireless communication has allowed many people around the world to live their lives and conduct business in ways that was never before possible. Millions of cellular subscribers have become accustomed to always having mobile Phones with them wherever they go. Now, businesses want to be able to connect to the office when ...

The existing synchronization solutions of mobile database are not independent from the database server because they use database dependent information such as metadata or use specific functions of database server such as trigger and time stamp. These constraints are critical weak point in cloud environment because various applications are running in various devices and servers ...
