    Introduction Wireless networks have grown in popularity. This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in 'Metcalf's law.' Metcalf's law states that if you 'connect any number, 'n,' of machines - whether computers, phones or even cars - and you get 'n' squared potential value.'[1] The incredible growth of the Internet seems to validate Metcalf's law. It then seems
