Since there isn't yet a list of satellite-related research on:
http://www.isi.edu/nsnam/ns/ns-research.html
here's a list I know of to date/token bibliography of satellite
networking simulation work resulting from the ns satellite extensions.

(The satellite extensions were first included in ns 2.1b6a; use of the
satellite plot scripts at
http://www.ee.surrey.ac.uk/Personal/L.Wood/ns/sat-plot-scripts/ is
indicated with a [*]).

The ns satellite extensions are outlined in:
Tom Henderson and Randy Katz, "Network Simulation for LEO Satellite
Networks," 18th AIAA International Communications Satellite Systems
Conference (ICSSC), Oakland, CA, April 10-14, 2000. [*]

(and described in a chapter of the ns documentation which you
must have noticed) and were used to investigate geographic routing in:

Tom Henderson and Randy Katz, "On Distributed, Geographic-Based
Packet Routing for LEO Satellite Networks," Proceedings of IEEE
Globecom 2000, San Francisco, CA, Nov. 2000.

http://www.cs.berkeley.edu/~tomh/publications.html

This is presented in more detail in chapter 6 of:

Tom Henderson, "Networking over Next-Generation Satellite Systems",
PhD thesis, Dept of Electrical Engineering and Computer Science,
University of California at Berkeley, Fall 1999. [*]

http://www.cs.berkeley.edu/~tomh/thesis/

Some examination of TCP goodput across LEO satellite meshes was
carried out in:

Lloyd Wood, George Pavlou and Barry Evans, "Effects on TCP of routing
strategies in satellite constellations", Special issue on
Satellite-Based Internet Technology and Services, IEEE Communications
Magazine, vol. 39, no. 3, pp. 172-181, March 2001. [*]

(DV routing across a static mesh was used for the multipath 
comparison) and handover discrimination in the presence of diversity
was explored in:

Lloyd Wood, George Pavlou and Barry Evans, "Managing diversity with
handover to provide classes of service in satellite constellation
networks", in the proceedings of the AIAA International Communication
Satellite Systems Conference (ICSSC '01), vol. 3, session 35, no. 194,
Toulouse, France, 17-20 April 2001. [*]

Those are written up in more detail in:

Lloyd Wood, "Internetworking with satellite constellations", PhD
thesis, Centre for Communication Systems Research, University of
Surrey, February 2001. [*]

http://www.ee.surrey.ac.uk/Personal/L.Wood/publications/PhD-thesis/

There's also:

Merkourios Karaliopoulos, Rahim Tafazolli and Barry Evans, "TCP
Performance on Split Connection GEO Satellite Links", in the 
proceedings of the 19th AIAA International Communications Satellite
Systems Conference (ICSSC '01), Toulouse, France, 17-20 April 2001.[*]

where TCP splitting and terrestrial links were implemented with the ns
satellite extensions (no personal webpage). That builds on work
described in:

Merkourios Karaliopoulos, Rahim Tafazolli and Barry Evans, 
Enhancing TCP's performance over GEO satellite links with split-
connections and link level retransmissions, London Communications
Symposium, London, UK, 14-15 September 2000.

which uses ns and snoop, but not the satellite extensions.
