An adaptive CAC algorithm based on fair utility for low earth orbit satellite networks

Abstract

A novel adaptive call admission control algorithm for multimedia low orbit satellite networks was proposed. Based on real-time call dropping probability of destination cell, the algorithm is able to reserve bandwidth for handoff calls combining probability threshold method and fair utility allocation scheme. Simulation results show that the proposed algorithm presents satisfactory new call blocking probability and greatly reduces handoff call dropping probability, while guarantees the high bandwidth utilization.
