XSTP performance analysis over nanosatellite networks

Résumé

Traditional satellites are extremely expensive to design, build, launch and operate. Consequently, both the aerospace companies and the research community have started directing their attention to missions involving many, small, inexpensive satellites, working in formation flying to achieve the same performance as a large, expensive, single satellite.There are many challenges to be resolved before the ambitious objectives of efficient communications within nanosatellite constellations can be achieved, including design of specific protocols that take into consideration the limited onboard resources, limited communications opportunities, limited bandwidth, high-speed node mobility, the types of errors founded in LEO nanosatellite environment, scalability, timing and synchronization issues. All these challenges require us to revise communication protocol design, network management, and to consider novel routing mechanisms to accomplish "more with less". Moreover, one of the most significant challenges of future nanosatellite network telecommunications will be provide some type of service guarantees for different types of traffic. This will be a particular challenge for streaming video applications, which often require a significant amount of reserved bandwidth to be useful.
