  3. What is a Mobile Ad Hoc Network (MANET)? According to Internet Engineering Task Force (IETF), a MANET is an autonomous collection of mobile users that communicate over relatively lower-bandwidth wireless links.

  4. Focus Today, I will focus on one critical issue in MANETs, that is, “Multicast Routing”.

  5. Design-Challenges of a MANET The development of routing protocols with the key features: • Robustness • Simplicity • Energy conserving

  6. Expected advantages from multicast routing • Providing efficient bandwidth • Reducing communication cost • Efficient delivery of data • Supporting dynamic topology

  7. Technical constraints for multicast routing • Minimizing network load • Providing basic support for reliable transmission • Designing optimal routes • Providing robustness, efficiency, and adaptability

  8. Classification Globally, there are two main categories of multicast routing protocols: • Tree-based protocols, and • Mesh-based protocols

  9. Examples of tree-based protocols • Multicast Ad hoc On-Demand Distance Vector (MAODV) routing protocol • Associativity-based Multicast (ABAM) routing protocol

  10. Multicast Ad hoc On-Demand Distance Vector (MAODV) • Extends AODV to offer multicast capabilities • Builds shared multicast trees on-demand to connect group members • Capable of unicast, broadcast, and multicast

  11. Associativity-based Multicast (ABAM) • Constructed in an attempt to reduce communication overhead and end-to-end delay

  12. An example of mesh-based protocols • On-Demand Multicast Routing Protocol (ODMRP)

  13. How ODMRP works? • ODMRP is based on a mesh structure for connecting multicast members using the concept of forwarding group nodes. • When a data packet reaches a multicast receiver, the receiver creates a Join-Table and broadcasts it to the neighbors.

  14. How ODMRP works? (cont.) • Each group member propagates the Join-Table until it reaches the multicast source via the shortest path. • This process constructs and updates the routes from the source to the receiver, creating a mesh of nodes.
