Novel Branching-Router-Based Multicast Routing Protocol with Mobility Support

Abstract

To cope with challenging problems faced by traditional multicast routing protocols, many branching-router (BR)-based multicast routing schemes with desirable features have been proposed. However, the current BR-based methods still lack efficient multicast management and suffer from a long join latency, leading to a disappointing mobility performance. In this paper, we propose a novel BR-based multicast architecture with a corresponding multicast routing protocol supporting multicast receiver mobility. In the proposed multicast architecture, a new management entity called multicast controller (MC) is used to handle most of the multicast management-related tasks, while other routers in the network construct a multicast tree according to the proposed Branching-Routerbased Multicast routing protocol with Mobility support (BRMM). Besides, the fast handover of multicast service can be supported by BRMM through the pre-establishment of temporary multicast paths. Through extensive simulation and analysis, we show that BRMM outperforms existing protocols and has many other attractive features.

Distributed Constraint Optimization Problems and Applications: A Survey

“…Choudhury, Dey, Dutta, and Choudhury (2014) presented a DCOP model for this problem where agents correspond to network entities, variables correspond to services, and their values are either 1, if the associated agent is willing to provide/forward the service, or 0, otherwise. Clients' service requests are mapped to servers' service offers, accounting for the delays that occur when traversing between intermediate nodes using a routing multicast protocol (Yan, Lee, Shen, & Qiao, 2013). Moreover, in order to provide a service, all requested QoS requirements need to be satisfied.…”
