This paper introduces a combined geographic and a Media Access Control (MAC) protocol for mesh, ad-hoc and cognitive networks. For mesh and ad-hoc networks, this paper examines the end-to-end (source to destination) link performance characteristics when supporting multimedia traffic. This paper also explains the cognitive network concept prior to analyzing cognitive network related results. The performance...
NASA is planning manned exploration missions back to the Moon and on to Mars. Space-based applications, which are required to be energy efficient for these missions - may have to operate in environments with intermittent connectivity, long latencies, and possibly with relay nodes. This paper overviews protocol stacks from IEEE, IETF, and CCSDS appropriate for these missions
We present advanced technology developments in space networking achieved under the Interplanetary Network Directorate Information Technology Program. Progress has been made in three primary areas: (1) distributed on-board scheduling as it applies to communications; (2) middleware services; and (3) communications protocols. Demonstrations of these capabilities have been provided using a simulation...
