Over the past decade a number of wireless communication networks have emerged for urban and indoor areas to complement the traditional cellular networks. The services provided by these networks are geographically selective. As a result, a wireless communication terminal needs to connect to multiple points of connection and perhaps multiple networks as it moves from one location to another. The process of supporting the change from one wireless point of connection to another is referred to as handover or handoff. The Internet Engineering Task Force's mobile Internet protocol is a widely accepted standard that uses mobile agents to support seamless handoffs, making it possible for mobile hosts to roam from subnet to subnet without changing IP addresses.
