Scalable Multicast Routing For Ad Hoc Networks, Manoj Pandey, Daniel Zappala
Scalable Multicast Routing For Ad Hoc Networks, Manoj Pandey, Daniel Zappala
Faculty Publications
Routing in a mobile ad hoc network is challenging because nodes can move at any time, invalidating a previously-discovered route. Multicast routing is even more challenging, because a source needs to maintain a route to potentially many group members simultaneously. Providing scalable solutions to this problem typically requires building a hierarchy or an overlay network to reduce the cost of route discovery and maintenance. In this paper, we show that a much simpler alternative is possible, by using source specific semantics and relying on the unicast routing protocol to find all routes. This separation of concerns enables the multicast routing …
