Abstract: WSNs is a collection of sensor nodes with the capacity of recognizing, physical changes from the environment such as pressure, wind, air pollution, temperature, humidity, forest fire detection, vibration and many others wirelessly among themselves. Coverage of a sensor node is one of the factors that affect the strength and reliability of wireless sensor
Abstract: Sensor nodes are deployed in oreder to observe the surrounding environment for some phenomena of interest in wireless sensor networks. The problem with observing such environments is covering entire area which reflects how well a region is monitored. The random distribution of sensor nodes caused by none-uniform deployment leads to coverage holes in the
Abstract: Multifactor authentication (MFA) uses two or more forms of authentication to permit computer users to access an application using the electronic authentication method after successfully providing two or more factors.
