Vehicular Ad hoc Network (VANET) consists of group of moving vehicles acting as nodes, establishing its own dynamic topology for packets exchange. The vehicles or the nodes are usually travelling at high speeds, resulting into a frequently varying topology. In this paper, we present performance analysis of latest IEEE standard 802.11ac in comparison with previous MAC protocols like 802.11p and 802...
In today's world usage of location based services on mobile devices such as smartphones, tablet PCs and laptops has become progressively popular. Even though location based services are proved to be very useful and convenient, they may cause risk to the users' location privacy, because for the retrieval of useful information based on user's location, user has to send his/her present location and the...
Induction Machine (IM) is the most widely used electrical motors due to its reliability, low cost and robustness. Working on the IM is one of the good research areas where simulation of IM has been performed using various modeling tools like LabVIEW, MATLAB/Simulink. The simulation of IM has been done using IFOC (Indirect Field Oriented Control) and DTC (Direct Torque Control) algorithms which involves...
Gamma Ray Spectroscope (GRS) is a system to detect, measure, analyze and display the Gamma Ray Spectrum. It consists of 4k Multi Channel Analyzer (MCA), 1.5” × 1.5” Thallium activated Sodium Iodide(NaI(Ti)) scintillation detector and a PC based MCA software. MCA has all the required facilities to handle the scintillation detector and to convert the signals from detector into meaningful data. MCA software...
Web Applications today rely heavily on database for storage of information & processing of the same. In the same time plenty of threats & security attacks are being launched against web — applications that are aimed to inject commands and gain unauthorized access to the sensitive information from the back-end database. Plenty of attacks exploit vulnerabilities of web-based applications, with...
Mobile Ad Hoc Networks (MANETs) have several features, such as dynamic topologies, limited bandwidth usage, limited energy, etc… Vehicular ad hoc networks (VANETs) are a special case of mobile ad hoc networks. VANET communication can be formed between vehicles with vehicle to vehicle (V2V) communication or between Vehicle-to-Road Side Units (V2R). VANETs provides a promising network scenario for facilitating...
In wireless ad hoc networks such as Vehicular Ad Hoc Networks (VANET), limited coverage of WiFi and high mobility of the nodes generate frequent topology changes. Therefore Quality of Service (QoS) support becomes an essential aspect. In this work we have identified the need for QoS improvement in VANETs. Survey of related work depicts that, an efficient routing strategy plays a crucial role, to improve...
Spam is also known as junk mail or Unsolicited Commercial Email (UCE) which has become major problem for the sustainability of the internet and global commerce. Everyday millions of the spam mails are sent over internet to targeted population to advertise services, products and dangerous software etc. A number of spam detection algorithms have been proposed to classify emails on content based, but...
