fields like algorithms‚ automata theory and artificial intelligence. However‚ I have been specifically attracted to the field of computer networks and would like to specialize in it. The logic in it is truly uncomplicated and yet water-tight. My first brush with practical execution occurred as early as in the 3rd semester‚ while making an autonomous robot with sensors programmed through the computer parallel port. However‚ it did not work as intended. After gaining considerable knowledge and experience

economic analysis of wireless communications by evaluating the two available alternatives. First is related to licensing and spectrum property and second to wireless communications‚ in order to evaluate the tradeoffs between property rights in spectrum and open wireless networks. It also explains that open wireless networks are likely to be better at optimizing the ability of users to communicate without wires than could spectrum property based systems. The open wireless network approach shifts
