Call Blocking Probabilities in LEO Satellite Networks : The Single Orbit Case
نویسندگان
چکیده
We study the problem of carrying voice calls over a LEO satellite network, and we present an analytical model for computing call blocking probabilities for a single orbit of a satellite constellation. We have devised a method to solve the corresponding Markov process eÆciently for up to 5-satellite orbits. For orbits consisting of a larger number of satellites, we have developed an approximate decomposition algorithm to compute the call blocking probabilities by decomposing the system into smaller sub-systems, and iteratively solving each sub-system in isolation using the exact Markov process. Our approach can capture blocking due to hand-o s for both satellitexed and earthxed constellations. Numerical results demonstrate that our method is accurate for a wide range of traÆc patterns and for orbits with a number of satellites that is representative of commercial satellite systems.

متن کاملAn Analytical Model for Calculating Bounds on Call Blocking Probabilities in LEO Satellite Networks
We present an analytical model for calculating upper and lower bounds for call-blocking probabilities in a LEO satellite network that carries voice calls. The method is especially useful for large systems where calculation of call-blocking probabilities are too expensive. Our method calculates upper and lower bounds very easily and produces fairly accurate results.
متن کاملA Markov Model to Calculate New and Hand-off Call Blocking Probabilities in LEO Satellite Networks
We derive a Markov Model to calculate new call and hand-off call blocking probabilities in LEO satellite networks carrying voice calls. The model is used to define blocking conditions for new and hand-off calls. The satellite constellation is treated as a group of M/M/K/K queues effecting each other with a set of constraints.
متن کاملAn Effective Routing Algorithm for Low-earth Orbit Satellite Networks
A new routing algorithm for Low-earth orbit (LEO) satellite networks is designed in this study. For this reason genetic algorithms are used. A new objective function is obtained to find the suitable path according to the criteria of the delay and an aging factor. Also Call Blocking Probabilities (CBPs) are considered due to the dynamic nature of the satellite systems. This dynamic routing type ...
