In today's world high speed network plays a very important role for different applications. A peer-to-peer network satisfies the condition of high speed communication between nodes within the network. For efficient communication between nodes within the network multicarrier modulation technique needs to be employed. To achieve multicarrier modulation technique WPM (Wavelet Packet Modulation) is one...
Vehicular ad-hoc networks (VANET) have gained importance in recent years due to urbanization and technical advancements. Vehicle to vehicle (V to V) and Vehicle to infrastructure (V to I) are important types of VANET which have been exploited to their optimum use for the comfort and safety of the people on roads and off roads. With the several other features of VANET which are already being implemented...
Performance of Cognitive Radio (CR) is affected by the estimation of availability of vacant channels based on traffic distribution observation of licensed users. Telecom traffic prediction at a particular instant depends on thorough knowledge of day of the week, hour of the day and instant of the hour. Distributed cooperative spectrum sensing is infrastructure based in which the sensor nodes themselves...
Wavelet Packet Modulation is an useful technique of multicarrier modulation that provides high bandwidth, efficiency and flexibility. This paper inquire, simulation of IEEE802.16 in MATLAB software using wavelet packet modulation in WIMAX. The results show that BER performance of WPM system is better than OFDM which uses cyclic prefix and consequently has higher SNR. The study is simulated over an...
This paper present an idea about the wireless adhoc network which is used in vehicle to vehicle Anti-Collision design system for determining collision course between two or more number of vehicles. This system is giving an idea to generate node information that can be used for finding location awareness between the vehicles. Searching of other vehicles in the moving area is of primary importance to...
The rise and scale of vehicles today makes traffic management a steady problem. Various method such as toll based control systems with electronic smart card recognition, advance warning of traffic status to the control system, and fixed time traffic control signal system are some of the techniques can be used to improve the traffic woes of passengers. However a problem is still remains due to incomplete...
The vehicular communication protocols in the context of Vehicular Ad-Hoc Network (VANET) are typically based on simulation models, because the practical experiments are not feasible. One of the main challenges in the Vehicular Ad-Hoc Network domain is the Realistic Simulation of Inter-Vehicle Communication (IVC) protocols. For providing meaningful evaluation result of IVC protocols, an exact modelling...
In recent years there has been a growing interest in the field of vehicular networks, primarily due to the advancement in technology and need for safety and entertainment applications. The current generation of vehicles has embedded computers, GPS receivers, and number of sensors, where as the next generation of these vehicles will potentially have short-range wireless network interface. The target...
The innovation in wireless technology is to support in the areas of Intelligent Transport System (ITS). Wireless technology can be used in Vehicle-to-Vehicle and vehicle-to-infrastructure in transport applications. ZigBee is the key protocol for sensor network applications because of the long battery life, low-cost for installation, eases maintenance and small footprint. ZigBee enables mesh networking...
