As the scale of small satellite network is not large and the transmission cost is high, it is necessary to optimize the routing problem. We apply the traditional time-expanded graph to model the data acquisition of small satellite network so that we can formulate the data acquisition into a multi-commodity concurrent flow optimization problem (MCFP) aiming at maximizing the throughput. We use a...

In this paper, we propose a verification method for risk management system of the electric power grid (RMS-EPG) using satellite communication network. The RMS-EPG with satellite communication network should be verified with various contingencies for its design and maintenance. For the verification of RMS-PG, the proposed system composed of the satellite communication simulator and the Power flo...

the use of satellite data in an estimation of air temperature (ta) near the earth’s surface has turned into an effective way for a large area of high spatial and temporal resolution. throughout the present study, artificial neural network (ann) as well as m5 model tree were employed to estimate ta in khuzestan province (south west of iran), using satellite remotely sensed land surface temperatu...

Recent development of technologies and methodologies on distributed spacecraft systems enable the small satellite network systems by supporting integrated navigation, communications and control tasks. The distributed sensing data can be communicated and processed autonomously among the network systems. Due to the size, density and dynamic factors of small satellite networks, the traditional net...

In this paper, a distributed multicast routing scheme is introduced for multi-layered satellite IP networks, which include GEO, MEO, and LEO layers. This scheme aims to minimize the total cost of multicast trees in the satellite network. Multicast trees are constructed and maintained in the dynamic satellite network topology in a distributed manner. Simulation results are provided to evaluate t...

An approach is presented for improving the spatial estimation of leaf area index (LAI) of a heterogeneous forest by integrating the Physiological Principles Predicting Growth (3-PG) model output with the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery. LAI was chosen as the variable of interest because leaf area is the exchange surface between the photosynthetically acti...

To accomplish network layer integration of terrestrial and satellite IP networks, special exterior gateway protocols are needed. In this work, a new exterior gateway protocol calledBorder Gateway Protocol Satellite version (BGP-S) is introduced that enables automated discovery of paths that go through the satellite network. This protocol is designed to work in only one terrestrial gateway in ev...

Satellite network, especially low earth orbit (LEO) satellite network, which has advantages of global coverage and short round-trip time (RTT), has played an increasingly important role in the future generation of global communication network. Due to fast velocity, frequent handover and time-varying topology, designing effective routing algorithm for LEO satellite network has always been challe...

ROUTING AND NETWORK MOBILITY MANAGEMENT IN NEXT GENERATION SATELLITE NETWORKS Satellite networks are an attractive option to provide broadband telecommunication services to globally scattered users, due to their extensive geographic coverage, high bandwidth availability, inherent broadcast capabilities, etc. Satellites rotating in geostationary orbit (GEO) are very well suited for broadcast ser...
