  1. Multicast Routing in WMNs COSC 6590 Fall 2007

  2. Approaches • Minimum cost trees (MCTs) • Shortest path trees (SPTs) • Recent work: • Ruiz et al. redefines tree cost • Chou et al. proposes double path routing for more reliable delivery • Xu & Nguyen compares the performance of MCTs and SPTs in WMNs • Some others

  3. Projects Project 1 • Implement either the SDM or MDM algorithm by Chou et al. in QualNet. • Compare the performance of SDM/MDM with that of the SPT algorithm (double path routing vs single path routing). Project 2 • Implement a simple core-based tree (SCBT) protocol in QualNet. • Similar to PIM-DM but we use SPT, not DVMRP, to build a tree rooted at the core • Compare the performance of SCBT with that of the SPT algorithm (core-based trees vs share-based trees). Note • The SPT code will be given for comparison.
