In order that we can freely investigate multi-input multi-output (MIMO) systems of any antenna diversity, a 3-D mix-diversity MIMO channel model is presented, and based on which a special algorithm, to which a Kronecker approximation method is applied, is raised to calculate correlation coefficients between any pair of sub-channels in various antenna diversity MIMO systems.
Mobile IP and NEMO (network mobility) provide continuous connectivity to the Internet to a node or a mobile network when moving from one access router to another. Because of link switching delay and IP protocol operation, packets destined to mobile nodes or mobile networks can be delayed or lost during the handover period. This paper proposes solutions to improve the performance of handover in the context of Mobile IPv6 and NEMO. We introduce a new control entity for both MIPv6 and NEMO to manage the traffic between access routers and mobile nodes or mobile routers, to provide low-latency and low packet loss for real-time services during the handover.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
