Abstract
Fundamental methods used in space research and exploration are continuously changing and developing, depending on the major scientific target of the community. Currently, we use space probes and expensive rovers to discover and analyze the surface of solar system bodies. However, these rovers could be replaced with thousands of cheaper sensors which are organized into a sensor network. In order to monitor the surface and the atmosphere of a solar system body, positioning accuracy and energy efficiency are key determining factors in such a network. In this article, a mobile sensor network capable of measuring and forwarding data on the surface of a distant planet is investigated, and several problems of spatial positioning are addressed.
Highlights
Sensor-based networks offer advantages compared to the currently used methods in space research
Extended basic positioning algorithm (EBPA): We extended the previously described Basic position algorithm without optimization (BPA) with heuristic optimization
The Positioning algorithm based on hop number (PAHN) algorithm generates less error and the error of the EBPA is between these two values with 3.2 meter
Summary
Sensor-based networks offer advantages compared to the currently used methods in space research. The NASA and European Space Agency (ESA) tests different sensor-based solutions like Seamless IP Diversity based Generalized Mobility Architecture (SIGMA) or Disruption Tolerant Networking tools [1,2]. Deploying sensors on the surface of distant planets will allow remote monitoring of non- accessible areas in preparation for human or robotic missions. For such kind of network, the mobility of sensing devices is an important element, due to the potential valuable scientific results gained from different sites, as opposed to static landers. It is possible that in the future, thousands of cheap sensors will be placed on the surface of distant solar planet
