I. INTRODUCTION
Engineers and developers could soon find themselves swimming in an extended alphabet soup of technologies, protocols and specifications as activity in wireless networking picks up quite elegantly and promisingly. The dawning of the 21st century has seen unprecedented growth in the number of wireless users, applications, and access technologies. As networking and communication domains are turning out to be fertile breeding grounds, a compendium of novel and promising topologies, services and infrastructures is emerging to surmount all the weaknesses that have gripped the current wired as well as wireless communication ecosystem. The leading network types are
Body Area Network (BAN), Personal Area Network (PAN), Local Area Network (LAN), Metro Area Network (MAN), Wide Area Network (WAN)
