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)
With an increased emphasis on transportation safety requirements, Vehicular Ad-hoc Networks (VANETs) have emerged as the key underlying technology in the realization of Intelligent Transportation Systems (ITS). The IEEE-1609 set of standards for Wireless Access for Vehicular Environment (WAVE) specifies an architecture that includes new standards for(More)
This paper presents a novel scheme for self configured dynamic sensor networks based on zones, where the sensor nodes are location aware. Location about which the sensors provide the information is always more important than identification of sensors. It is vital to deliver this information to sink involving minimum packet processing at intermediate nodes(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)
—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)
