Sparse mode multicast as a mobility solution for internet campus networks

Research output: Chapter in Book/Report/Conference proceedingConference paper


his paper presents a model for merging IP multicast and Mobile IP principles in order to create Multicast for Mobility Protocol (MMP) which provides fast handoffs and location independent addressing for mobile hosts in foreign networks. MMP uses Core Base Trees (CBT) protocol, a sparse mode multicast routing protocol, as the main mechanism for handling packet transmission to mobile hosts in foreign networks. The main objective is to minimise network incurred delays during handoffs which mostly occur during updates of either mobility agents on home networks or sources of packets. The selection of a sparse mode multicast protocol for creating multicast trees for a virtual multicast group of a mobile host is proven in this paper a valid choice compared to standard Mobile IP mechanisms due to the efficient, fast and local route updates during movements between points of attachments.
