Vehicular Ad Hoc Network (VANET) is the subgroup of the Mobile Ad Hoc Network (MANET). VANET interconnects the nodes for transferring secure information between nodes, here vehicle acts as a node. VANET is used to provide safety and efficiency in transportation system. Many traffic signals are used to reduce accidents in the roads, but since it is not much effective. Hence VANET is used; it use...
Breast cancer (BC) is the most common malignant disease in women, with most patients dying from metastasis to distant organs, making discovery of novel metastasis biomarkers and therapeutic targets imperative. Extracellular matrix (ECM)-related adhesion proteins as well as tumor matrix stiffness are important determinants for metastasis. As traditional two-dimensional culture does not take into...

Computing real-time road condition is really tough and it is not achieved using GPS. However, a malicious node can create multiple virtual identities for transmitting fake messages using different forged positions. A malicious vehicle can disseminate false traffic information in order to force other vehicles and vehicular authorities to take incorrect decisions. To overcome these difficulties w...
In recent years, the development of the Intelligent Transportation System (ITS) has increased the popularity of vehicular ad hoc networks (VANET). A VANET is designed to enable vehicles to exchange information about traffic or vehicle conditions to help other vehicles avoid traffic accidents or traffic jams. To resist malicious attacks, all vehicles must be anonymous and their routings must be ...
Wireless access vehicle environment (WAVE) architecture of intelligent transportation system has been standardized in IEEE 802.11p standard and it is going to be widely deployed in many roadway environments in order to provide convenient services. However, the IEEE 802.11p contention-based medium access control protocol would significantly downgrade transmission efficiency between road side uni...
This paper addresses an unfairness problem that exists among vehicles of distinct velocities in IEEE 802.11p based vehicle-to-infrastructure (V2I) networks used for drive-thru Internet applications. The standard IEEE 802.11p does not take into account, the residence time of vehicles within the coverage of each road side unit (RSU), for granting channel access. Due to this, a vehicle moving with...
IEEE 802.11p is an approved amendment to the IEEE 802.11 standard to facilitate wireless access in vehicular environments (WAVE). In this article, we present an analytical model to evaluate the impact of vehicle mobility on the saturation throughput of IEEE 802.11p-based vehicle-to-infrastructure (V2I) networks. The throughput model is then used to investigate an unfairness problem that exists ...
