Abstract:

According to the feature of mobile Internet over wireless link, a new handover scheme for mobile wireless IP networks is presented based on the idea of cross-layer design. The proposed scheme will forward the packets to the mobile host in the network layer with multicast protocol and employ the trigger information from the link layer in order to construct the multicast tree. The numerical analysis discloses that the proposed scheme can shorten more handover delay and reduce the packets loss ratio more efficiently than Mobile IP protocol and Hierarchical Mobile IP protocol. The signaling cost during the handover also decreases obviously in the proposed scheme so that plenty of radio resource is saved.

Key words: mobile IP, handover, link layer trigger, multicast, cross-layer design
