Abstract: Based on the analysis of the algorithms of fixed random neighbor selection, a new variable random neighbor selection algorithm adaptable to hybrid P2P in live multimedia streaming networks was presented. The new algorithm measured fitness degree of node with its capacity factor. Different types of nodes have different maximum neighbors. Simulations show that the new algorithm can reduce the transmission delay and improve the performance of network system.
