Descripción
"The concept of multiple satellite missions is becoming attractive because of their potential to perform coordinated measurements of remote space with greater temporal and spatial resolution, which can be classified as a sensor network or generally as Cyber-Physical System (CPS). Multi-satellite missions require a reliable and cohesive network between the small satellites. This paper represents our initial work on developing an inter-satellite communication link (ISL) that takes into account the symbiotic behavior amongst the system of satellites. The Open Systems Interconnection model (OSI) will be used as a framework for ISL. The data link, in particular the Multiple Access Control (MAC) layer, will be our primary focus. This paper discusses the communication design issues of PNSats within a sensor network construct. A hybrid combination of Time Division Multiple Access (TDMA)/Code Division Multiple Access (CDMA) scheme for a cluster of satellites is proposed. It consist of a TDMA-centric and a CDMA-centric approach which will address the problem of multiple access in heterogenous small satellite networks, where agents have different data transmission rates. This method can also extend the application of small satellite networks in terms of scalability. We will validate through simulations that the CDMA-centric achieves high throughput with minimum delay."
