Sensors are tiny devices and senses different types of inforamation. The sensing range of each sensor is limited due to its energy holding capability. Active participation of sensors in data transmission to base station minimizes the overall energy consumption and also reduces the overall systems cost. In this regard division of the total sensor field wiht uniform grids is the best solution. Leveling...
In Cognitive Radio technology, spectrum sensing is a fundamental component. Secondary users may utilize the frequency bands of primary users when these bands are not being used. To support this spectrum reuse functionality, secondary users are required to sense the radio frequency environment. Eigenvalue ratio based spectrum sensing is one among the best achievable solutions. In this paper, we have...
