Our work focuses on signaling processes, during handoff between and networks. Particularly, the MAC layer technologies of and are examined in great detail. The SIP-based handoff procedure consists of the following sub-procedures: (i) Mobile Host (MH) initialization at MAC layer, (ii) Acquisition of a new IP address using Dynamic Host Configuration Protocol (DHCP) in a newly connected network, (iii) SIP terminal mobility management process for both pre-call mobility and mid-call mobility. Our analytical results and experimental results show the signaling delay and overhead of handoff between and heterogeneous networks.
