Now-a-days the most of straight wired network systems are replaced by the wireless network systems. The authors know the main difference in between these two is the change from a fixed network location to mobile network location, i.e., an address is no longer a physical location and an address will reach the wireless station. The main advantage of wireless networks is flexibility, easy installation & quick maintenance. A wireless network can also support customers who move from one place to another (mobility). The wireless radio channel acts as a medium for reliable high-speed communication. It is not only liable to interference, noise and other channel obstructions and these obstructions depend on time (time-varying) in unpredictable ways due to user indiscriminate movement.
