Dynamic Team Formation on Team-Oriented Multicast Yiguo Wu and Siavosh Bahrami Tutor: Yunjung Yi Outline LANMAR Previous work: Dynamic team formation Our modified dynamic team formation protocol Preliminary results Discussion LANMAR MANET challenge: scalable routing Hierarchical Routing Protocol Assumption: “group affinity model” Benefit: scalable routing Limitation: assumes logical subnets known in advance Dynamic Team Formation Xiaoyan Hong ,Mario Gerla, Dynamic Group Discovery and Routing in Ad Hoc Networks, In Proceedings of Med-Hoc-Net 2002. No subnet assumption Two Phases: Phase 1) Initialization: traveling companion discovery, K-Hop clustering (connectivity, lowest ID, heuristics), and initial elections Phase 2) Maintenance: Hysteresis rule for stable landmark election Phase 1 stability issue? Stability Problem Confirmation Advertisement Protocol Algorithm Details:Routing Table Exchange Exchange local routing tables with direct neighbors periodically How frequently should we exchange local routing tables? Protocol Algorithm Details:Companion Identification Identify Companions Routing Table entry not “stale” Has been present in local routing table for at least time t (avoid roaming nodes) Protocol Algorithm Details:Election Elect Clusterhead Lowest ID Companion Pros: Stable Simple Fast Cons: Most likely not close to the minimum dominating set (optimal), i.e. many small clusters that may require further merging Note: in current implementation, every election is independent of the previous one raising stability issues (add maintenance heuristics?) Protocol Algorithm Details: Close Proximity Merge Small cluster problem - Clusters overlap each other Solution: Low Cost Merging - Observation: If landmarks can see each other directly, then their corresponding clusters overlap. - Action: Merge them ! Protocol Algorithm Details:Confirmation Advertise Confirmation Tentatively elected node can “respond” in 2 ways: If it is its own landmark, or has not
