Handoff Study in Mobile Networks Using Mobile IP

Wireless LAN and mobile devices are becoming very popular because of its characteristics like connections without any physical cabling links. To make wireless devices working on built-in communication stack, it is important to consider Internet Protocol layer. For mobile networks IETF has proposed Mobile IP that provides facilities to roam between base stations while mobile devices moves between different cells transparently to application and higher level protocols. This paper provides the brief look on mobile IP architecture and then discusses the future research issues that should be resolved to increase the effectiveness of this protocol.
