Wireless networks and mobile computing technologiesare having a profound impact on IP-based networks, astheir basic protocols were designed without assuming mobilityof the network nodes. More recently, protocols likeMobile IP have been designed to handle global mobility,and micro-mobility protocols have been proposed for themanagement of intra-domain mobility. However, these protocolsdo not address important issues required for seamlessmobility, such as candidate access router discovery,target access router determination, and context transfer. Inthis paper, we identify the problems related to seamless mobility,underline design considerations to be observed whendesigning seamless mobility solutions, and propose an architecturethat can be used as a framework for the implementationof these solutions.
