【Abstract】 We propose a distributed fair cost delay constrained multicast algorit hm that finds a multicast tree between one source node and multiple destination nodes in communication networks. The algorithm can find the multicast tree which satisfies the delay constraint and allocates cost fairly among all destination nodes with optimal tree cost. At the same time, we propose a approximate algor ithm, which keeps the fairness of cost allocation among all destination nodes an d decreases the amount of message exchanging between nodes.更多还原
