Preventing Phishing Attacks Using One Time Password and User Machine Identification
Recent improvements in wireless communications and acoustic technology have enabled the use of sensor networks in underwater surface. Underwater Sensor Networks is an emerging field which requires research in the field of routing and channel access. Applications using offshore exploration, assisted navigation, Oceanographic data collection and tactical surveillance applications use Underwater Sensor Networks. Some applications such as disaster prevention require minimum delay in data gathering. And also care must be taken to make sure that the energy expenditure of an underwater sensor node is minimal because replenishment of a sensor node is not cost-effective.
