A bundle of problems

Abstract

Highly elliptical orbits can be used to provide targeted satellite coverage of locations at high latitudes. We review the history of use of these orbits for communication. How elliptical orbits can be used for broadband communication is outlined. We propose an addition of known elliptical orbits to the new equatorial O3b satellite constellation, extending O3b to cover high latitudes and the Earth's poles. We simulate the O3b constellation and compare this to recent measurement of the first real Internet traffic across the newly deployed O3b network.

Architectures for the future networks and the next generation Internet: A survey

“…Such a notion of reliability is relevant in the DTN context as against the end-to-end principle since the source node may not be connected long enough to ensure end-to-end reliability. Recently, there have been criticisms of the bundle protocol about its efficacy in disrupted and error prone networks and can be referred to at [184]. Several other features of the bundle protocol may be obtained in detail from the relevant RFC's [158,24,35,149,19].…”

Security analysis for Delay/Disruption Tolerant satellite and sensor networks

“…Also, the access control process will have impact on the flow process (routing) of DTN bundles but yet, there is not identified mechanism for flow characteristic enhancement in DTN. Therefore it is still an active research field [9]. …”

Security analysis of DTN architecture and Bundle Protocol Specification for space-based networks

“…For network-centric operations involving diverse organizations, it may not be possible from a security standpoint to accept time reference data from nodes operated by a different organization, even though data communications with that organization are deemed acceptable [7].…”

“…Bundle protocol implementations that support these more dangerous operations will need to exercise extreme care [7]. "…”
