Performance
Scientific paper
The Planetary Satellite Network consists of the satellites orbiting the planets to provide communication relay and navigation services to the surface elements, which are often spread out to form an Ad hoc network. However, the current TCP/IP layered protocols have very poor performance in the Planetary Satellite Network, which is characterized by extremely high propagation delays, link errors, asymmetrical bandwidth and blackouts. In this paper, a novel cross-layer protocol design that supports adaptability and optimization across multiple layers of the protocol stack is presented to solve the performance problem of the Planetary Satellite Network. This cross-layer feedback design on a Planetary Satellite device aims to optimize overall network performance by increasing local interaction among protocols, decreasing remote communications, and consequently saving network bandwidth, improving the QoS performance.
