Mobility between dissimilar networks is one of the trends in network design with the availability of multi-mode terminals moving towards fourth generation telecommunication systems. Overlaid networks provide support to such multi-mode terminals in an efficient and scalable way. Handoff support for multi-mode terminals under overlay networks involves dynamic resource reservations to guarantee smooth handoff. Wireless overlay networks present new problems in achieving efficient resource reservation for handoff support. Signaling protocols to support handoff between such heterogeneous standards might take a long time to evolve and can be insufficient. Such signaling might not be elaborate to facilitate efficient resource reservations to support inter-technology handoff. In this paper, we suggest the use of mobile agents that travel through the Internet backbone across system boundaries to establish a communication channel between heterogeneous wireless systems and specifically help in usage context gathering at the boundary of overlaid wireless networks for achieving efficient resource reservations.
