| description | Snapshot is a fundamental notion proposed for routing in mobile low earth
orbit (LEO) satellite networks which is characterized with predictable topology
dynamics. Its distribution has a great impact on the routing performance and
on-board storage. Originally, the snapshot distribution is invariable by using
the static snapshot partition method based on the mechanical steering antenna.
Utilizing nowadays advanced phased-array antenna technology, we proposed a
quasi-dynamic snapshot partition method based on the inter-satellite links
(ISLs) reassignment for the polar-orbit LEO satellite networks. By steering the
inter-satellite antennas when snapshot switches, we can reassign the ISLs and
add available ISLs for a better following snapshot. Results show that our
method can gain more stable routing performance by obtaining constant snapshot
duration, constant ISL number and lower end to end delay. Especially for
Iridium system, our method can gain not only longer merged snapshot duration,
half of the snapshot number, but also higher utilization ratio of inter-plane
ISLs. Potentially, our method could be very useful for the Iridium-next system. |
