A Distributed QoS Multicast Routing Algorithm Based on Ant Algorithm for LEO Satellite Networks

摘要

Multicast provides an efficient way to distributemultimedia information to different destinationssimultaneously. To enhance the multicasting performance, anew Distributed QoS Multicast routing algorithm based onAnt algorithm is proposed for IP LEO satellite networks. Bysimulation, we compare the performance of our multicastrouting algorithms with Shortest-Path Tree algorithm andRectilinear Steiner Trees algorithm, the results show that ourscheme can meet the delay-constraint, avoid link congestion,realize load-balancing, and achieve the minimal network cost.
