In this paper a novel cross layer mobility management scheme for IEEE 802.16e standard is proposed using cellular IP (CIP) and fast mobile IPv6 (FMIPv6). The research focuses on the use of CIP for intra domain and FMIPv6 for inter domain mobility management. A cross layer design is considered to enable smooth integration of link layer triggers and their use for the benefit of network layer. The network model used is a hierarchical one, which allows integration of CIP and FMIPv6 into the IEEE 802.16e, mobile-WiMAX, network.
