In this research, WiMAX and WiFi on Vehicular Ad-hoc Networks (VANET) is examined which are used to evaluate the best service provider technology for VANET. In VANET the nodes are moving very fast and change their network infrastructure rapidly, which have very short time to communicate with each other. Both WiMAX and WiFi is be used as per their features(More)
Testing is one of the critical processes in software development life cycle. It plays key role in the success of software product by improving its quality. Web-based applications are emerging and evolving rapidly; their importance and complexity is also increasing. Heterogeneous and diverse nature of distributed components, applications; along with their(More)
Software Testing is an important area of research in the field of software engineering because it is the deciding factor for successful project release and directly proportion to software quality and reliability. A lot of research has been already done in this field, likely to be leveraged in future as software has become integral part of each and every(More)
In recent years, wireless sensor networks (WSNs) featured an exponential growth, which has revolutionised the field of telecommunication. A wireless sensor network consists of a group of tiny battery powered sensor nodes capable of reading, processing and reporting the data to the Base station (sink).One of the major issues faced by sensor nodes is the(More)
Early detection of breast cancer increases the survival rate and increases the treatment options. One of the most powerful techniques for early detection of breast cancer is based on digital mammogram. A system can be developed for assisting the analysis of digital mammograms using log-Gabor wavelet statistical features. The proposed system involves three(More)
Mobile ad hoc networks (MANETs), due their inherent resource constraints and other limitations has prompted the researchers to device energy and bandwidth efficient transmission techniques and protocols. This objective has confronted scientists with the conflicting requirements of energy efficiency and latency. Most of the well known energy efficient(More)
Future mobile communication demands high mobility of user. An effect of this movement is that mobile users change its base station (BS) at much higher rate. Hence, handover is one of the most important aspects of mobility management for any cellular mobile technology. We have developed an analytical model for finding the handover rate in a cellular network.(More)
—We consider layered decode-forward (DF) cooperation in a relay-aided wireless multicast network. Splitting the source-message into two equal layers, we provide unequal power allocation to the individual layers through a simple mapping operation on a QAM constellation. The layering process thus allows the destinations to partially recover the message from(More)
