    Digital and Analog Comparison

    Technology is constantly changing in communications. The analog signal was used for several years and was limited in number and did not have the ability to handle the amount of data interchange used today, because of the size requirements. Analog signals are still used today, but are more complex and are in most circumstances converted to a digital signal. This paper will compare the different types of analog and digital technology we used and are currently using today.…

    Routing in Wireless Sensor Networks

    A Wireless Sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional, also enabling control of sensors activity.…
