Abstract The integration of mobilead‐hocnetworks (MANETs) with the Internet provides flexible and multi‐hop communication capability in hybrid wired and wireless networks. Existing architectures for integrating these networks use Mobile IP andad‐hocrouting protocols with fixed gateways. In this paper, we propose a mobility management scheme based on a mobile gateways (MGs) architecture. We designed a buffering mechanism for micro‐ and macro‐mobility management in hybrid networks. The performance of mobility management with optimized handover (MM‐OH), optimized handover with prediction (MM‐OHP) and forced handover (MM‐FH) are evaluated using simulation. Our simulation results show that a buffering mechanism coupled with the hybrid gateway discovery results in a higher packet delivery ratio for MM‐OH and MM‐OHP compared with the MM‐FH scheme. The MM‐OHP scheme has a lower number of handovers compared with the MM‐OH scheme. Moreover, the simulation experiments reveal that the speed of the MG has a relatively higher impact on performance than the speed of mobile nodes. Copyright © 2007 John Wiley & Sons, Ltd.
