Stability Control in Polygon Based Topology Formation and Information Gathering in Satellite Based Wireless Sensor Network

The Space today has considerable surge in distributed network of small satellites to meet the imperative demand of both commercial and scientific applications (Selva and Krejci in Acta Astronaut 74:50–68, 2012). As the complexity of the design and launch of large satellites is high , the need of distributed networking is gaining lot of interest in space domain as well. Thus single large satellite is replaced by many, small satellite that collaboratively work to perform the same functionality of single large satellite forming Space Based Wireless Sensor Network (SBWSN). The SBWSN are dynamically decoupled network as each satellite, orbits in its own path and the positioned with considerable distance between them. Stability of network with respect to formation flying to accomplish the task by collaboration is quite essential. In this paper, we develop the stability criteria in small satellite network using graph theory, covariant derivatives and linear algebra to ensure distributed processing and communication, required to accomplish the mission task.
