Study of Multicast Receivers Grouping Algorithm Based on Clustering
Zhang Jun-ya · Journal of Shenyang Jianzhu University · 2009
A multicast grouping algorithm based on cluster is proposed in order to save bandwidth,improve transmission efficiency and assure fairness among receivers with different receiving capability.The receivers with similar receiving capability are put into one group.This algorithm is compared with other receiver grouping algorithms under two evaluation criterias of multiple session fairness:max-min intra-session and social welfare fairness.On the premise of fairness,receivers in the same multicast session are divided into different groups with the specific transmission rates.The simulation results show that in case of not having too many groups,the performance of the multicast grouping algorithm based on cluster is between max-min intra-session and social welfare fairness algorithms.Multicast receiver grouping algorithm based on cluster can save bandwidth,improve transmission efficiency and assure fairness among receivers with different receiving capability.
