Abstract: The development and proliferation of wireless networks has contributed to the evolution of our daily lives. Mobile users can move between heterogeneous networks, using terminals with multiple access interfaces. Thus, the most important issue in such environment is the Always Best Connected (ABC) concept allowing the best connectivity to applications anywhere at anytime. To answer ABC requirement, various vertical handover decision strategies have been proposed using advanced tools and proven concepts. In this paper, two architectures interconnecting a UMTS network and another Wimax have been presented. Each architecture uses a protocol for mobility management, namely MIP and SIP. To evaluate the two procedures, we are given two indicators, the signaling cost and the vertical handover delay. To evaluate our scenarios, we have established a specified signaling messages flow diagram specific to each scenario, one based on the MIP and the other based on the SIP. Then, we have given expressions for each of the two indicators mentioned above that we have implemented in MATLAB. The results show that, generally, the scenario based on MIP has lower signaling cost and delay than the scenario based on SIP.
