| Abstract: | In the very near future, we shall witness the coexistence of networks with heterogeneous
link layer technologies. Such networks will naturally overlap each other and
mobile users will need to frequently handoff among them for a number of reasons,
including the quest for higher speeds and/or lower cost. Handoffs between such
hybrid networks should be fast enough to support demanding applications, like multimedia
content delivery, but also secure enough since different network providers
are involved. This gets even more complicated considering that network providers
may not simultaneously be multimedia service providers as it is the case today. In
order to support security operations in a large scale the employment of an AAA protocol
is mandated; however, this adds more delay to the handoff process. This article
analyses and compares the prominent methods proposed so far that optimize the
secure handoff process in terms of delay and are suitable for uninterruptible secure
multimedia service delivery. |
