What shared tree should we build? G=(V, E) is undirected graph. A positive, real cost assigned to each edge in E. Given a subset of nodes S in V, the Steiner tree is the minimum cost tree that …

This heuristic combines Dijkstra’s algorithm for calculating the the minimum spanning tree and Dijkstra’s algorithm for calculating the minimum depth tree algorithms.

Minimum Cost Tree Routing Algorithm Goal: minimize the overall cost of the multicast tree Minimum Spanning Tree: Minimum cost tree which spans all nodes (Prim-Dijkstra’s algorithm: add nearest members one by one to the tree) Example: Minimum Steiner Tree: Minimum cost tree which spans at least all the group members

For example, the KMB (Kou, Markowsky, and Berman) algorithm. generates multicast trees with an average cost of 5% more than the ideal SMT (see [10]). The KMB algorithm builds. a heuristic SMT based on the minimum spanning tree algorithm, which requires a centralized approach. This implies. updated to reflect the latest receiver connectivity.

Nov 29, 2021 · This paper proposes a multicast tree construction algorithm, which considers receiving devices and network capability as base parameters to construct the multicast path.

For the same multicast example as in Fig. 3, Fig. 4a shows a source-specific multicast tree which employs unidirectional links3 (with source = CA1), while Fig. 4b shows a group-shared mul-ticast tree.

To solve the problem, a current approach for efficiently supporting a multicast session in a network consists of establishing a multicast tree that covers the source and all terminal nodes.

The energy-aware Multicast tree can be constructed using a genetic algorithm (GA) [26], in order to provide reliable transmission over wireless networks.

An example of the solution tree of a multicast connection with one source and two destinations is given in Fig. 2. As the number of leaves in each level grows exponentially, it is very...

and solving the Steiner tree problem. We start with a quick review of the Steiner tree problem and the echniques available for its solution. We then discuss algorithms for multicast routing that can be considered as extensions of
